PYHL-14A Fire High Temperature Smoke Exhaust Mixed Flow Fan

The PYHL-14A series smoke exhaust fan adopts CAD software multi-objective optimization design, with optional molded twisted wing conical impeller, built-in high-temperature motor, and a dedicated motor cooling system. Choose dual speed motor direct drive to achieve dual use of one machine (i.e. normal ventilation and air supply)

The PYHL-14A series smoke exhaust fan adopts CAD software multi-objective optimization design, with optional molded twisted wing conical impeller, built-in high-temperature motor, and 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 GA211-1999 Fire Protection High Temperature Resistance Test Method, it can operate continuously for more than 100 minutes under high temperature conditions of 400 ℃, and 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 around the world.

PYHL-14A fan type I has a compact single speed structure, saving installation space. The Type II dual speed fan is equipped with a silencer and collector at the air inlet, which reduces the operating noise of the fan during low-speed exhaust.
