Industrial fans and industrial ventilators are indispensable components in a wide range of industrial sectors, including the chemical and petrochemical industries, the automotive industry, steelworks, waste incineration plants and the cement industry. These systems are exposed to extreme conditions such as abrasion, corrosion and high or low temperatures and have to deliver top performance on a daily basis.

Even if they are made of robust materials such as structural steel, stainless steel or special materials such as ceramics and rubber coatings, they can occasionally fail. At such times, our experts are on hand to help you maintain your systems quickly and effectively.

Industrial fans Definition

Industrial fans and ventilators are critical components in industrial production facilities, factories, warehouses and laboratories. One of their purposes is to ensure a continuous supply of air or gas, which is essential for the process or to maintain occupational safety.

Compared to conventional fans for private use, industrial fans and industrial ventilators are characterized by their extraordinary performance and are designed to handle demanding environmental conditions. Depending on the model, they can not only circulate air with their impellers, but also ensure the safe transportation of process gases in production plants. Maintenance of the fans and blowers, especially for explosion-proof extraction, is essential for safe and long-lasting operation.

Our product range includes a wide selection of specialized industrial fans and matching accessories that integrate seamlessly into your process. This ensures that the air quality in your company is always fresh and safe.

Difference axial and radial

Axial fans and axial blowers Definition

Axial fans are a sub-category of industrial fans that are characterized by their specific mode of operation. These fans draw air or gas through the fan in an axial direction and push it out in the same axial direction. They are particularly efficient at generating a straight air flow and are ideal for applications where a high air flow rate is required with a low pressure difference.

Axial fans are often used in situations where the air needs to move in a straight line, for example in cooling systems, ventilation systems and cooling condensers.

Centrifugal fans and radial blowers Definition

Centrifugal fans, also known as centrifugal fans, are an important variant of industrial process gas systems. In contrast to axial fans, centrifugal fans move the air radially by accelerating it through the centrifugal impeller and directing it out of the housing. These fans are characterized by their ability to generate high pressures and are therefore well suited for applications where a larger pressure difference is required, such as in extraction systems and industrial drying processes.

Their versatile design makes it possible to adapt them to different requirements and ensure efficient air movement. A centrifugal fan, explosion-proof, is suitable for use in potentially explosive atmospheres.

Difference between fan and ventilator

Industrial fans and ventilators are two types of devices used in industrial applications for ventilation, cooling and air/gas movement. The main difference between them lies in the way they work and the specific tasks they perform.

In summary, industrial fans are typically focused on generating airflow and circulation, while industrial fans are more versatile and capable of generating or regulating higher pressure air/gas flows, making them suitable for specific industrial applications.

Industrial fan:

  1. How they work: Industrial fans are usually simple devices that draw in air and blow it out into the environment. They generate air flows to move or circulate the air in a room or system.
  2. Applications: Industrial fans are often used for general ventilation of rooms or to remove harmful gases and vapors. They can also be found in heating, ventilation and air conditioning systems.
  3. Mode of operation: These fans are usually capable of moving large volumes of air at lower pressures. They are effective when it comes to improving air quality and balancing the temperature in a room.

Industrial fans:

  1. Functionality: Industrial fans are more powerful and more complex than industrial ventilators. They can not only move gases, but also substantially increase the pressure in the system. This enables them to suck or blow air through filters, pipes or ducts.
  2. Applications: Industrial fans are used in industrial processes where it is necessary to generate or control gas flows at higher pressure. They are used in applications where air or gas must be filtered, transported or compressed, such as in exhaust gas cleaning, pneumatic conveying systems or in ventilation systems for production plants.
  3. Operating principle: These fans can move air or gas at a higher pressure and are therefore ideal for applications where the air/gas flow must pass through filters, pipes or ducts with a certain resistance.

Reasons for repairing fans and blowers

The reconditioning of industrial fans is a crucial service for various industrial applications. These machines are often customized for special purposes and are driven by specific motors, which is why the procurement of standard machines is not always possible or involves long delivery times.

Other reasons are:

  • Specialized design: Industrial fans are often specially designed for specific applications, which makes it difficult to obtain replacement machines.
  • Complexity of the repair: The repair requires a wide range of specialist knowledge, from the repair of the drive unit to the mechanical overhaul of the complete fan.
  • Cost-effectiveness: Repairs are often more cost-effective than buying a new machine.
  • Maintaining air quality: Repaired fans help to maintain occupational safety and air quality in industrial environments in the long term.
  • Environmental protection: Maintenance avoids unnecessary waste and consumption of resources through the purchase of new machines.

Where are industrial fans and industrial ventilators used?

Industrial ventilation systems are widely used in various industries. Areas of application include the chemical and plastics industries, wood processing, machine and tool construction, the metal industry, the agricultural and food industries, the automotive industry and the construction and raw materials industries. In these sectors, they are used for various tasks such as cooling, drying, cleaning and extraction and are therefore indispensable components in industrial processes.

When are explosion-proof fans necessary?

An explosion-proof fan is required in situations where an explosive atmosphere can occur or is already present. This is particularly the case in industrial environments. In principle, explosion-proof fans are required in all situations in which flammable substances may be present in the exhaust air and there is a risk of explosion, for example in the chemical and pharmaceutical industries or in wood processing.

The type of explosion-proof fan can vary depending on the area of application, so a wall fan can be explosion-proof, a tube fan explosion-proof according to DIN 125 or a completely different variant of explosion-proof fans can be used. The use of these special fans helps to ensure the safety of employees, systems and the environment.
