Fire Type Centrifugal Axial Flow Fire Exhaust Fan
HTF series high-efficiency axial flow fan, using CAD software multi-objective optimization design, its basic form for axial flow structure, according to different uses can be divided into fire protection, explosion-proof, general ventilation three; Fire motor can use high temperature resistant motor, the product according to XF211-2009 "fire smoke exhaust fan high temperature test method" for high temperature test risk through the response department of product certification from the heart 3 death of the original certification can be continuously operated for more than 30 minutes under the medium temperature 280 high temperature storage. Continuous operation at 100ºC for 20 hours/time without damage.
The explosion-proof type is designed to meet the requirements of an explosion-proof environment and necessitates a special fan. Our company has obtained the compulsory CCC certification for our explosion-proof products. The explosion-proof level of the entire machine is Ex dbll BT4 Gb, making it suitable for flammable and explosive gas areas.
General ventilation can be divided into single speed, double speed and frequency conversion according to the field needs (fan motor adopts frequency conversion motor, equipped with frequency conversion controller, frequency conversion speed regulation to meet the needs of different working conditions, frequency conversion fan is recommended to lock the adjustment frequency (25Hz-50Hz), two-speed fan is generally high speed for smoke exhaust, low speed for general ventilation.
