Unit Profile :
The TK-BF series cabinet type fans use forward-curved, mul -blade, double-inlet centrifugal fans
that have been dynamically and sta cally balanced, ensuring high efficiency, smooth opera on, and
low noise. The cabinet structure is robust, with both internal and external surfaces powder-coated
for excellent corrosion resistance and rust preven on.
These units are widely used in ven la on systems requiring air purifica on and HVAC applica ons,
including commercial buildings, hotels, banquet halls, auditoriums, basements, factory workshops,
etc.
(Product standards: GB 10080-2001, JB/T 9068-2017)
The standard series includes 12 models, available with motor internal or external, direct drive or
belt drive. Direct drive models offer three adjustable speed se ngs (high, medium, low) for flexible
airflow adjustment. Airflow ranges from 900 m3/h to 58,000 m3/h, and sta c pressure ranges from
150 Pa to 800 Pa. Custom manufacturing is available for special customer requirements. For fire
protec on applica ons, the external motor version has passed high-temperature tes ng, capable of
con nuous opera on for more than 40 minutes at 300°C, mee ng the requirements for fire
protec on fans.
Us e :
When paired with an air energy recovery unit: It provides the necessary airflow for the energy recovery system.
Function of Ventilation Fan:It operates independently to supply or exhaust air for a room.
Function as a Pressure Booster Box:It is installed in series within the air duct and used in conjunction with other ventilation
equipment (such as fresh air ventilators, air handling units, modular air conditioning units, and air purification units) to increase
airflow pressure in the duct. This helps address insufficient air volume caused by excessive resistance in long duct systems.
Nomenc la tur e
BFH is for High Static Pressure Box Ventilation Fan Unit
