Industrial fans, in substantial terms, have taken on an almost capital importance in everyday life. In the hottest seasons, the heat increases considerably every year and tools of this kind are essential resources in all respects for the well-being of workers and
of the company itself. From a technical point of view they stand out for their technical characteristics and design conformity. Here, then, is an overview about it.

How a fan is made and when it is suitable by law

Industrial fans, whatever they are axial or centrifugal, as well as all electronic products, must comply with precise European regulations in order to be considered safe and suitable to be placed on the market. The rule that regulates, in this sense, the installation and extraction methods is called UNI ISO 13349. What makes a fan perfectly suitable from a practical perspective is the type of installation towards which it can tend. There are exactly four on a functional level: free suction and delivery, free suction with pipe delivery, pipe suction and free delivery, pipe suction and delivery. The function of the guards to be considered becomes fundamental when using type A installation. It allows essential elements such as suction and delivery to be kept away from accidental impacts and pressures. Type B includes guards on both the suction and delivery fronts.

Scale fixing which is also common to type C assembly (with pipe suction). Only type D is characterized by the total absence of guards positioned on the fan's delivery and intake. At this point the assembly, valid for all types of ventilation, makes use of an anti-vibration joint capable of providing greater stability to the instrument, avoiding wear and structural vibrations.

In order for legal suitability to also be guaranteed in terms of safety, a series of conditions must be respected against anomalies and improper manoeuvres. For example, never remove safety devices or shelters yourself unless expressly specified in the instruction manuals. The use of the fan in circumstances and contexts other than those indicated in the compliance directives is prohibited. Just as it is not advisable in the slightest, if not strictly prohibited, to act independently on defects and malfunctions that may compromise its stability.

Better to follow a very precise and sequential process from a procedural point of view. In the event that an operator has the necessary skills to be able to act in this sense, he must, at the same time, possess personal protective equipment. Small precautions, but they can save lives on both fronts.

Fans for potentially explosive environments

The fans produced by MZ Aspiratori, of which we are resellers, comply with the 94/9/EC directive and designed according to the EN14986 standard which indicates fans intended for potentially explosive atmospheres.

The Atex certified fans have been designed and built for use in areas classified as 1/21 and 2/22 and are suitable for conveying flammable and combustible substances, in compliance with the indications of the ATEX Directive 2014/34/EU. There ATEX directive and CE marking require compliance with the machinery directive, for which the Atex fan, at a regulatory level, must be considered as a partly completed machine and therefore completely protected, since it is integrated into more complex systems. Even if the safety of the systems is guaranteed, the protections must still be left with the fan and also in anticipation of a possible change of intended use of the same.

Tutti i ventilatori standard MZ Aspiratori conformi alla direttiva ATEX, sono stati esaminati dalla commissione del TÜV NORD ed hanno ricevuto la relativa certificazione.

In the ever-expanding industrial sector there are various products for domestic, professional and various entertainment uses, which implement increasingly cutting-edge technology with growing functionality. In this case we will focus on a type of fan that is unknown to most people and which for this very reason we will explore in detail. It's about the Plug Fans, which you can find in our section special products. We will take a closer look at what it is, so what Plug Fans are, why they are useful, how to choose them carefully and in the best version and model. A comprehensive review about ventilation tools which would otherwise be unknown and which instead deserve attention in the industrial field. A focus that highlights the pros, cons, purposes of use and methods of ordering and purchasing one of the best products currently available in the immense field of ventilation and entrepreneurial aspiration.

What are Plug Fans

Let's start from a first point of analysis of Plug Fans, i.e. what they are and how they are characterized in their structure. These are industrially produced elements truly exceptional, often implemented within limited systems to expand their ventilation potential. In fact, often industrial ones, like i centrifugal fans and axial, and they are large in size and cannot be installed properly. So the Plug Fans come to the rescue, fans of smaller sizes, but like their larger version they are able to perfectly satisfy any ventilation need and ventilation of spaces such as ovens, plenums, cabins and so on. The absence of the snail in their construction allows for easy use of these fans which therefore become essential especially in those narrow and closed spaces.

Why plug fans are useful

We therefore come to the crux of the issue related to these industrial fans: that is, why they are so useful. The answer is soon given, Plug Fans represent an ideal alternative in those cases where the significantly reduced dimensions of the spaces of installation do not allow the application of normal industrial fans. The smaller size and flow rate of Plug Fans comes into play as a mini version of traditional ventilation systems. This aspect has a significant impact on the choice made by those responsible in using this ventilation option compared to larger models. This is for the same performance, as these fans have the same impellers as the standard types; the only flaw if we want to find it in the Plug Fans is given by the difference in performance level of this instrument as it is often conditioned by the systems in which it is integrated. But leaving this aside, we must recognize this ventilation model as an authentic flagship of the industry, which can be purchased specifically on the Meridiana Aspiratori website.

How to choose Plug Fans

Choosing a Plug Fan might seem like an age-old practice to carry out, especially if you are familiar with this industrial element for the first time. These reduced version ventilation systems require in-depth knowledge to ensure that they can be useful for the cause and purpose of preference. Therefore, know well in which spaces to install them, and the systems in which to integrate them to make them run at their best in terms of performance. That said, the factors on the basis of which a correct choice must be made are roughly two: power and structural materials. The first aspect concerns the ventilation capacity and therefore satisfies the basic criterion for which a similar product is purchased. The second aspect, the structural one, has the guarantee of longevity over time in the construction materials. A decidedly important feature to avoid having to resort to maintenance too many times which does not always solve a given ongoing problem.

Why order them from Meridiana Aspiratori

We have therefore gradually traced the intrinsic characteristics of Plug Fans, which play a leading role in the industrial sector, especially in those spaces with small dimensions where traditional standard fans find installation and application difficult. We have seen the functions and implementation systems of these fans, therefore ovens, cabins and plenums, which optimal contexts and locations to incorporate these indispensable ventilation elements. Furthermore, the absence of the scroll and the same impellers as the superior models allow the performance conditions to be set without having to suffer too much during the processing phase compared to traditional versions. Ultimately it is necessary to remember how There are many types of fans available on our site, as well as accessories. as the main sales site for these industrial products which we always tend to innovate. In fact, on our website you can consult the catalog of fans in detail, including plug-in fans. Regardless of the product involved, the site mentioned provides a 360-degree descriptive overview with useful information for the final purchasing decision. For example, if you search for a industrial fan, Here the dedicated section appears in the web interface with the possibility of going deeper with the specific characterization and understanding what is the best choice to make for your company. In short, Meridiana Aspiratori represents the answer to the question of why to choose that particular type of fans (but also other suction or ventilation elements) through the aforementioned portal. Complete information, excellent assortment, and constant updating on the latest models on the market, as absolute certainties of quality.

In the continuously developing and expanding industrial sector, adequate use of the means of making the air healthy both for the products produced and for the employees at work appears increasingly indispensable. Preserving certain environmental conditions is essential in order to develop, especially in the chemical field and related contexts, adequate final products. So produce yes, but also protect the health of those who find themselves having to carry out their tasks in closed environments on a daily basis and where it is therefore necessary to guarantee a certain degree of healthy air. In this case elements such as industrial fans come into play air extractors, also present for large volumes. Cylindrical air circulators, in particular, which can be of various types. So let's focus our attention on them and find out more about the models and choice of the best ones currently on the market.

Types of air circulators

As announced in the introduction, there are various types of industrial fans, also known as circulators or air extractors. Essential elements in companies, especially those in contact with chemical products, to make the environment in which they operate healthy. That is both to protect the health of employees and to maintain stable conditions for production purposes. Just think of the pharmacological and similar fields to understand how fundamental all this is for the purpose of production. There are therefore various models of air circulators: from cylindrical to axial, through to models that can be fixed to the external industrial roof and so on. In short, a wide range of tools that can be used for installation inside or outside an industry and make it capable of cleaning the air and making it circulate properly to preserve workers' health and environmental production conditions.

Intended use of air circulators

Obviously when we talk about types of air circulators everything must be contextualized and also related to the relative intended use of the same. In fact, depending on the environment to be "cleaned" or "cooled", a specific model or ventilation, recirculation system etc. is chosen. For example there are i industrial car parks, or even chemical companies, not to mention fire-fighting structures, where each of the aforementioned requires a specific type of circulator. Space-saving axles, to name one model, are more suitable for car parks; those with ducts or rings are more suitable for installation in industrial warehouses and therefore relating to the production sector.

Resistance and longevity over time

Two of the most popular features dei ventilatori industriali e quindi anche dei circolatori d’aria sono sicuramente la resistenza dei materiali costitutivi, e la durata nel tempo, in particolare della serie ACF che abbiamo a disposizione sul our site. In fact, these tools, which are so useful for cooling or cleaning environmental production air, have their home advantage precisely in temporal resilience. This allows them to have little need for maintenance other than annually for routine checks. An aspect of no small importance for those who have the task of monitoring and, if necessary, replacing the aforementioned company elements.

Guide to choosing the best air circulator models

After having reviewed all the various information regarding air circulators and more generally industrial fans, we now come to the main topic: that is, the guide to choosing the best models currently available on the market. First of all, it is necessary to distinguish the material to be removed through purification: therefore whether it is micro dust, oily mists, dust from dry processing, dust from flammable materials or from the production of precious metals. Each of the mentioned processes involves a different pollutant that must be cleaned through the use of air circulators. The cylindrical ones represent the best weapon against these pollutants which make the working environment harmful both for the employees and for the final yield of the product. Once the nature of the air pathogen is understood, we move on to the selection of ventilation and recirculation models. In this sense, there are three main models ranging from 18 to 26''. The latter are equipped with an aerodynamic aluminum fan to significantly reduce noise. Therefore not only functionality but also minimal noise emissions which do not impact the ideal processing conditions. Extremely simple both to install and maintain, these circulators are also made with galvanized or stainless steel bodies for maximum resistance to corrosion.

The industrial sector is full of tools that are fundamental within the production chains and manufacturing processes. Many of these are unknown to most, being of purely technical relevance to employees and professionals. But actually understand what these are crucial elements of the industrial chain, and how they operate, is essential not only for information purposes but also to understand how much development, technical and mechanical skills there are behind the large area of ​​industry. In this case in this circumstance we will focus our attention on industrial engines, extractors and the various types of both of these key tools in the sector in question.

Types that you can find in the catalog of our products on the site.

Types of industrial motors

Let's start this in-depth study on the industrial sector and in particular on industrial motors, starting from the types currently used. First of all we need to do a first distinction between alternating current and direct current electric motors. Then from here there would be a second distinction to make between those previously mentioned and the step-by-step ones.

AC motors

Starting from alternating current motors also known as alternators, these are powered and operated by a non-constant current flow. They base them on a structure that hinges its essence on two elements: the stator and the rotor. The first constitutes the base, the fixed part, while the second is a sort of rotating metal superstructure. These two elements, coming into contact with each other through the intermediation of a magnetic field, power the motor. The aforementioned type of industrial motor is usually used for the operation of industrial washing machines, sewing machines and various types of household appliances.

DC motors

Despite the previous typology, this one involves direct current, therefore a constant flow and not an alternating process. There is one for this type of machine difference between brushed and brushless motor. The substantial difference is in the installation of the windings: in the case of brush motors it is on the rotor; in the brushless ones instead on the stator. The presence or absence of these copper fins then affects the power supply of this type of motor precisely because there is contact between the fins. While in the case of alternating current motors the field of application was that of household appliances, washing machines, sewing machines and so on, in the case of continuous cycle motors we move to the automotive, healthcare-medical, automatic vending and video surveillance sectors.

Stepper motors

The third and final type of industrial motor is that concerning stepper motors, which can be unipolar or bipolar. In the first case the power supply in the windings proceeds in the same direction, in fact the same one; in the second, however, it is directed in both directions. The degree of angle then distinguishes various models of this type of motor: from those with permanent magnets with a 90% angle to those with a round angle. The field of application here is robotics, servomechanisms or even telescopes: in short, all those instruments that require extreme rotation speed and angular movement for their function.

Operation of industrial electric motors

We have already partly touched on this issue in the distinction between the different types of industrial engines, with those with continuous and alternating cycles. In fact, in this regard we have highlighted the different power supplies available to the two motors, which in turn differ from the stepper motors. In short, depending on the variation in energy, the final product also varies and consequently its functioning. It sometimes involves the magnetic field, sometimes the brushes or even the angle rotation. A plurality of mechanisms where each has its own specificity and refers to a different field of application. In the case of alternating current motors, the voltage can even reach thousands of volts and, thanks to the use of the stator and rotor, it generates this energy armature. In continuous cycle motors, however, as mentioned, it is the brushes (copper blades) that play an important role, since through their contact they manage the flow of the rotor and stator (hence the brushless motors). Finally, the step-by-steps that focus on the electrical impulses of the windings. It is the latter that convey the energy induced into the motor and diversify its range of action: which is distinguished by rotation angles and axis displacement.

Operation of industrial extractors

Ultimately we focus our attention on industrial air extractors, equally important to the engines analyzed above. In fact, these machines allow the exchange of air within industries, which, especially when in contact with chemical agents, require a certain status of environmental conditions. In order to preserve not only the environmental conditions for the processing of chemical products and similar, but also the health of employees, extractors therefore play a central role. They are based on huge fans which suck air from the affected environment to convey it towards the outside. Depending on the power of the engine that powers them, these machines are able to move an increasingly greater quantity of cubic meters of air. Operating through the principle of natural conversionTherefore, the air extractor is able to remove fumes, dust and chemical agents from the environment, making it healthy and improving the conditions of use. There are various types: from wall-mounted to those mounted on the roofs of industrial warehouses. The former are more for interiors, and are placed in the crucial areas of accumulation of fumes and toxic substances of an industry. The latter, however, are positioned outside, also due to their large dimensions, and improve the air flow while preserving their working conditions. In fact, they are not subject to corrosion from external agents or particular maintenance due to their cutting-edge coatings and materials. The best extractors are those that manage to carry out the task of air exchange while maintaining a certain thermal comfort. So a double feature that allows us to quickly understand which are the best models to focus on.

The industrial sector is a world made up of various elements that, when combined, ensure the development of a product. There are many productive fields, from food to mechanics, from metal processing to the processing of materials that make up objects functional for everyday life. However, regardless of the final result, the production chain revolves around tools among which we also find the extraction tower. torrino di estrazioneLet's see what it is and how this component represents a necessary element in certain companies. So, characterization and purpose of what in many cases is much more than a mere extractor.

What is an extraction tower

After making a necessary introduction to the topic, let's first examine the meaning of the term in question: the extraction tower. This term refers to a system used in industries for the low-pressure suction of certain volumes of air. This component is often noticed at first glance but many are unaware that it is defined in this way. To put it simply and less technically, the extraction tower is nothing more than that mushroom-shaped object that is usually connected to flues or more or less complex suction systems. It is placed on the roof of a structure to convey a certain volume of low-pressure air from the inside to the outside. Therefore, as anticipated in the introductory phase, it is a very useful element, especially when talking about chemical companies or those in contact with similar materials. Here, air filtration is fundamental both for preserving the environmental working conditions and for the protection of workers, and not just for the final product. This discussion helps us understand how this industrial component, often ignored, is actually crucial for maintaining certain environmental conditions inside a workplace. Just like its placement, the extraction tower is at the pinnacle of functionality, not just in material installation. It is the extreme point of a production chain that would otherwise be unable to fulfill its task.

Composition of the extraction tower

Having understood what the extraction tower is and particularly the context of its application, let's now shift our focus to its composition. Alvanized steel and glass in back resin are the two main components of the aforementioned object. These materials are used to make the dome and the part immediately below it functional for protection against atmospheric agents. Inside, there is a motor of varying power that drives a fan useful for air suction. This is very quiet during operation, contrary to what one might think. In fact, when thinking of an industry, the immediate thought is often of the noise and chaos from which workers have to isolate themselves using specific acoustic protection devices.

The range of extraction towers

There is a wide range of extraction towers, which you can also find on our websitediffering mainly in the power of the suction motor. There are nine different models of motors, all three-phase, providing significant drawing and subsequent filtering power. Alternatively, there are also single-phase models equipped with variable speed controllers to regulate the air flow. Depending on its characteristics, the extraction tower can operate up to a maximum temperature of 200 degrees. Such delicate operating conditions can only be sustained by materials like steel and zinc. In fact, the extraction tower is a component specifically designed as explained above to operate without any problems under the mentioned conditions.

Other technical features of the extraction tower

Let's now examine other technical features of the extraction tower, in addition to those listed so far. Among these, we find a proportional weight-to-size ratio conducive to proper functioning. This also greatly facilitates its mounting on roofs and tops of structures of interest. Indeed, the lightness of the component in question is aimed not only at its use but also at its insertion and relative installation. This factor also makes the extraction tower an extremely long-lasting element. It can last many years due to the galvanized and steel coating between the inner and outer parts. This aspect also has a positive impact on the economic side, as such exquisite manufacturing does not entail additional maintenance costs.The fan housed inside is perfectly stabilized to ensure there are no oscillations or unexpected movements. The motor powering it, being of great power in the vast majority of models, drives the fan at a high speed. This would affect the correct aspiration process if the aforementioned fan were not balanced. Not to mention the further impact on the quietness of the suction mechanism, always related to stabilization. In short, from what can be gleaned about the characterization and constitution of the tower, we are undoubtedly talking about a tool of artisanal excellence. A component that is made and designed not only for the task it must perform, but also for the protection and safeguarding of its usage conditions. The better the quality of its parts (motor, fan, etc.), the more likely it is to withstand the years. All this without having to resort to corrective and maintenance interventions, which are often not only costly but also invasive and not entirely effective. The extraction tower is therefore a key object in various types of industrial production, as it represents not just a mere air filtration and suction system, but an indispensable means for the protection of a work environment. Especially when the latter involves materials or chemical compounds, often releasing residues and fumes that absolutely need to be evacuated.

Active control of fans is of fundamental importance in many applications where it is necessary to regulate speed and airflow. This type of control offers various advantages depending on the context in which it is used.

Energy Efficiency: Active control allows for the adjustment of fan speed based on actual ventilation needs. This means that fans can operate at lower speeds when the demand for airflow is lower, saving energy and reducing operational costs.

Comfort and Indoor Air Quality: In building cooling and ventilation systems, active control helps maintain a comfortable indoor environment by adjusting fan speeds to avoid excessive drafts or sudden temperature fluctuations. It also helps maintain indoor air quality by effectively removing pollutants and allergens.

Noise Reduction:By reducing fan speeds when intense ventilation is not required, the noise generated by ventilation systems is also reduced. This is particularly important in noise-sensitive environments such as homes, hospitals, or offices.

Extended Fan Lifespan:The use of active control reduces wear and tear on fan components since they can operate at lower speeds with less mechanical stress when demand is low. This contributes to extending their lifespan and reducing maintenance costs.

Adaptation to Changing Conditions: Active control allows for adaptation to changing environmental conditions, such as temperature, humidity, or the presence of people in a space. This flexibility is crucial to ensuring optimal performance and a safe environment in different situations.

Enhancement of Industrial Process Performance:In industrial settings, active fan control is crucial to ensuring the proper functioning of production processes, product quality, and worker safety. It is used to control temperature, humidity, and the concentration of chemicals in the air.
