HTF (A) exhaust fan fire

 HTF (A) fire temperature exhaust fan axial multi-objective optimization using CAD software design, matching molded axial flow impeller, built high temperature motor, arranged a special motor cooling system. Use two-speed motor direct-drive, to one machine (that usually send row when high-temperature exhaust ventilation and firefighting), arranged after the electrical control box can be remotely controlled automatically. High temperature performance, high efficiency, small size, easy installation (horizontal, vertical, lifting can be), etc., are widely used in high-rise buildings, drying room, underground garage, subway, tunnels and other occasions to send fire smoke and exhaust ventilation . Press GA211-1999 Fire fan high temperature test methods, can run at 400 ℃ more than 100 minutes of continuous high temperature, medium temperature at 100 ℃ continuous operation 20 hours / time is not damaged, it has been approved for use by fire departments in major cities nationwide. Fans of the series may use the occasion of the installation requirements, peripherals silencer box, made HTF (A) -X box-shaped exhaust fan the fire. Second, the model description HTF (A) - X - Ⅱ - 8 W representatives rooftop, conventional non-character machine number (the number of impeller diameter dm) Model (Ⅰ single speed, Ⅱ double speed, III high pressure type) structure (X is box-shaped, conventional non-character) fire temperature exhaust axial fans
