Overview of Industrial Fan Types and Their Applications
Industrial fans differ in design, operating principle, and area of application. The main types of industrial fans and their intended uses are described below.
CCK TM Axial Fans
Axial fans generate a directed airflow parallel to the axis of the impeller and are designed to move large volumes of air at relatively low system resistance. Due to their high airflow capacity, compact design, and energy efficiency, they are widely used in general ventilation systems, smoke extraction systems, air pressurization systems, process equipment cooling, and ventilation of large facilities.
CCK TM axial fans are available in various configurations and are selected according to the required airflow rate and operating conditions.
CCK TM Centrifugal (Radial) Fans
Centrifugal fans operate by changing the direction of the airflow: air enters the impeller axially and is discharged at a 90-degree angle. This design enables significantly higher pressure generation compared to axial fans.
CCK TM centrifugal fans are widely used in systems with extensive duct networks, high aerodynamic resistance, as well as in industrial ventilation, dust extraction, and process ventilation applications. Depending on the intended use, the equipment can be manufactured in standard industrial, dust-handling, kitchen ventilation, explosion-proof, or fire-rated versions.
CCK TM Inline Duct Fans
Inline duct fans are designed for installation directly within the ductwork and represent one of the most versatile solutions for supply and exhaust ventilation systems. They feature compact dimensions, low noise levels, and easy installation.
CCK TM inline fans are manufactured for both round and rectangular ducts and are widely used in administrative, commercial, residential, and industrial buildings.
CCK TM Roof Fans
Roof fans are intended for installation directly on the roof of a building and are used in exhaust and supply-exhaust ventilation systems. This arrangement reduces duct lengths, optimizes the use of internal space, and simplifies maintenance of the ventilation system.
CCK TM roof fans provide efficient air extraction from industrial facilities, warehouses, retail buildings, office buildings, and public facilities. Depending on the application, the equipment may be used for general ventilation, removal of heated air, or as part of smoke extraction systems.
The fan design includes protection against atmospheric exposure, resistance to temperature fluctuations, and long-term operation in outdoor conditions. A wide model range allows selection by airflow capacity, pressure, and functional purpose for projects of any complexity.
CCK TM fans cover all major sectors of modern ventilation engineering and enable efficient solutions for residential, commercial, industrial, and special-purpose facilities while ensuring reliability, energy efficiency, and compliance with applicable standards.
Each fan type has its own purpose and is optimal for specific operating conditions. For example, axial fans are suitable for ventilating production workshops with large air volumes, whereas centrifugal fans are generally preferred for ventilation systems with higher pressure losses and greater system resistance.

Axial vs. Centrifugal Fans: Key Differences and Which Fan Is Better?
A common question is: which fan is better—axial or centrifugal? To answer it, it is necessary to compare the main characteristics and operating differences of these two fan types.
Fan Type | ||
Exhaust Fans | Removal of contaminated air, gases, fumes, and dust particles | Can be equipped with filters and silencers to improve air quality and reduce noise levels |
Cooling Fans | Heat dissipation and maintenance of optimal equipment operating temperatures | Widely used in HVAC systems, refrigeration equipment, and industrial cooling applications |
Supply Air Fans | Delivery of fresh outdoor air to occupied spaces | Used in mechanical supply ventilation and air-handling systems |
Axial fans are versatile devices designed to move large volumes of air while operating against relatively low system resistance. Centrifugal fans, on the other hand, are better suited for applications requiring higher pressure, such as dust extraction systems and complex duct networks with significant aerodynamic resistance.
Key Characteristics of Industrial Fans: What to Consider
When selecting an industrial fan, it is important to evaluate a combination of technical parameters that determine its efficiency and suitability for specific operating conditions.
The main fan characteristics include:
- Airflow capacity (air volume flow rate) – the amount of air moved by the fan, typically measured in m³/h.
- Pressure – static or total pressure generated by the fan, measured in Pa (Pascals) or mm H₂O.
- Motor power – affects energy consumption and overall performance.
- Noise level – an important factor for compliance with occupational health requirements and personnel comfort.
- Rotational speed – the motor speed that drives the fan impeller, usually measured in RPM.
- Construction material – determines resistance to corrosion and aggressive operating environments.
- Installation type – wall-mounted, floor-mounted, inline duct installation, etc.
What determines fan performance characteristics? Primarily, they depend on the blade design, blade angle, rotational speed, and impeller diameter.
How to Select a Fan Based on Airflow Capacity and Pressure
Successful fan selection begins with determining the required airflow capacity and pressure.
The selection process typically includes the following steps:
- Determine the required airflow rate (m³/h).
- Calculate the resistance of the ductwork and ventilation system (Pa).
- Select a fan capable of providing the required airflow at the specified pressure.
- Verify motor power and rotational speed requirements.
- Consider environmental conditions and operating requirements.

Depending on the operational requirements of an industrial facility, specialized fan types are selected. Each fan category features specific design characteristics and aerodynamic properties that must be considered during the system design stage.
What Determines Fan Performance and How to Calculate It
Fan performance is one of the most important parameters when selecting ventilation equipment. Airflow capacity depends on several technical factors:
- Impeller diameter – a larger impeller increases the volume of air moved by the fan.
- Rotational speed – the higher the fan speed, the greater the airflow rate.
- Blade design – blade shape and pitch angle directly affect airflow characteristics and overall efficiency.
- System resistance – duct length, bends, dampers, filters, and other components increase pressure losses and reduce overall system performance.
For accurate fan selection, engineers use performance curves that illustrate the relationship between airflow rate and pressure, as well as specialized airflow simulation and system modeling methods.
