PLHL. HTF (B) mixed flow fire smoke exhaust fan
PLHL. HTF (B) Fire Protection High Temperature Fire ProtectionSmoke exhaust fanAdopting CAD software for multi-objective optimization design, optional molded twisted wing conical impeller, fully enclosed and built-in high-temperature motor, equipped with a dedicated motor cooling system. Adopting a dual speed motor direct drive system to achieve dual use (i.e. high temperature smoke exhaust during normal ventilation and firefighting), equipped with an electrical control box for remote automatic control. It has the advantages of excellent high temperature resistance, large air volume, high wind pressure, and easy installation, and is widely used in high-rise buildings, drying rooms, underground garages, subways, tunnels and other occasions for fire smoke exhaust and ventilation. According to the GA211-1999 high temperature resistance test method for fire fans, it can operate continuously for more than 100 minutes under high temperature conditions of 400 ℃, and can operate continuously for 20 hours/time without damage under medium temperature conditions of 100 ℃. It has been recognized and adopted by fire departments in major cities across the country.
The HTF (B) type fan (PYHL-14A type) has a compact single speed structure, saving installation space. Type II dual speed fan is equipped with a silencer collector at the air inlet to reduce the noise generated by the fan during low-speed exhaust.All smoke exhaust fans use H-type high-temperature motors for single speed and dual speed motors.
