A CCK TM duct fan is a device installed directly inside a ventilation duct (air duct) and designed for forced air movement in supply, exhaust and general ventilation systems of industrial, commercial and residential buildings. Duct fans provide concealed installation, low noise levels and full integration into the building's engineering system. This solution is ideal for projects where compact design, aesthetics and high ventilation performance are important.
CCK TM offers a wide range of duct fans designed for air supply and extraction systems. The product range includes fans for supply and exhaust ventilation, industrial duct fans and equipment for complex engineering systems. The range includes both standard equipment and energy-efficient models equipped with EC motors.
How a Duct Fan Works
A duct fan operates by converting the mechanical energy of an electric motor into the kinetic energy of the air. The drive motor rotates the impeller, whose blades undergo static and dynamic balancing to ensure high efficiency and low vibration levels. As the impeller rotates, air is drawn in through the inlet, accelerated by centrifugal forces and directed toward the outlet, generating the required pressure in the system and ensuring air movement through the ductwork.
Duct Fan Design
The fan housing is made of corrosion-resistant galvanized steel, allowing the unit to be installed in any position. Some models feature a service cover for quick access and acoustically insulated housing, making the equipment convenient for maintenance and operation in areas with increased noise requirements.
The impeller is made of durable material and features backward-curved blades. This aerodynamic design provides high efficiency, low noise levels, stable operation under variable loads and minimal vibration, which is particularly important for duct fans.
The fans are equipped with asynchronous or EC motors, allowing precise speed control and reduced energy consumption while ensuring stable ventilation system operation.
The fan can be installed in both round and rectangular ventilation ducts, including installations using adapters. Standard flanges simplify installation and integration of the equipment into existing ventilation networks.
Types of CCK TM Duct Fans
The CCK TM product range is divided into several design groups — square, axial, rectangular and round duct fans — making it possible to select the optimal solution according to the shape and cross-section of the existing air duct. Each group includes several versions: standard models, acoustically insulated and energy-efficient models with EC motors, as well as specialized designs for demanding operating conditions.
Rectangular Duct Fans
Supply and exhaust duct fans are designed for general ventilation systems.
- Acoustically insulated housing — suitable for projects with increased noise control requirements.
- EC motors — provide precise speed control, low energy consumption and compatibility with modern automation systems.
- Explosion-proof design — intended for areas with a potentially explosive atmosphere.
- Radial fans — used where increased pressure in the duct is required.
- External motor — suitable for operation at elevated temperatures and under demanding operating conditions.
- Frame-and-panel design — used in medium- and high-capacity systems and convenient for maintenance.
Round Duct Fans
Standard fans for round air ducts provide a compact solution for residential and commercial ventilation systems.
- EC motors — energy-efficient fans with smooth speed control.
- Reduced height — suitable for installations with limited available space.
- Forward- or backward-curved blades — the appropriate configuration is selected according to the required pressure, airflow and noise level.
- Acoustically insulated housing — reduces aerodynamic and mechanical noise.
- Wall-mounted versions — suitable for local ventilation solutions and compact systems.
Advantages of CCK TM Duct Fans
The ability to install duct fans directly inside ventilation ducts provides a number of important advantages, making them suitable for supply and exhaust ventilation systems in industrial, commercial and residential buildings.
- Compact design and concealed installation. Exhaust and supply duct fans are installed directly inside the air duct, saving useful space and preserving the interior design. The absence of external components allows the equipment to be installed in technical areas, suspended ceilings, shafts and other confined spaces. Compact dimensions also simplify transportation, installation and maintenance.
- Low noise level. The design of duct fans ensures smooth airflow without abrupt changes in direction. Backward-curved impellers and acoustically insulated housings reduce noise and vibration, allowing the equipment to be used in offices, residential complexes, educational and medical facilities.
- High energy efficiency. Optimized aerodynamics and a wide range of EC models significantly reduce energy consumption. EC motors provide smooth speed control, improve efficiency and allow fan performance to be adapted to the actual system load, reducing operating costs.
- Versatile application. Duct fans are suitable for moving air through round and rectangular air ducts, providing exhaust ventilation, air extraction and combined supply-and-exhaust solutions. They are used in industrial facilities, shopping centres, warehouses, restaurants, offices and residential buildings. The models can operate in different installation positions and can be easily adapted to the requirements of the engineering system.
- Reliability and durability. Galvanized steel housings provide corrosion resistance, while the impellers undergo static and dynamic balancing. This reduces vibration, extends the service life of bearings and motors, and ensures stable fan operation under continuous loads. The duct fans are designed to operate across a wide range of temperatures and air dust levels.
- Easy maintenance. Models equipped with an integrated service cover provide quick access to the motor and impeller without removing the fan from the system. This simplifies routine maintenance and reduces operating costs. The compact design also makes maintenance possible in confined spaces.
- Flexible integration into ventilation systems. Standard connection dimensions, compatibility with round and rectangular ducts, the option of using adapters and integration into automated control systems make duct fans a versatile component of any ventilation network. They can be easily combined with axial duct fans, radial fans, as well as equipment from the Supply Air Handling Units and Industrial Fans categories.
Duct Fan Installation Recommendations
Installation of an industrial CCK TM duct fan requires compliance with several important technical requirements to ensure efficient and long-term operation. The fan must always be installed according to the airflow direction indicated on its housing, ensuring correct aerodynamics and stable airflow performance. The duct fan can be installed in any spatial position — horizontally, vertically or at an angle. The key requirement is to provide convenient access to the service cover and maintenance components for inspection, cleaning and servicing when required.
All duct connections must be airtight. Air leakage can reduce fan performance and place additional load on the motor. The use of flexible vibration-isolating connectors or supports is also recommended: they reduce noise and protect the fan housing from vibration loads, extending the service life of the equipment. It is also important to ensure that the ductwork is installed correctly and without misalignment, as improper geometry can increase airflow resistance and operating noise.
Before commissioning, make sure that the parameters of the transported air comply with the technical requirements of the selected model, including permissible dust concentration and temperature. After installation, commissioning and adjustment are performed: the impeller rotation direction, noise level, vibration and actual airflow are checked. This approach ensures correct fan operation and maximum ventilation system efficiency.
