The axial flow fire smoke exhaust fan is equipped with a high temperature resistant motor and a special motor cooling system. It can run continuously for more than *0 minutes under high temperature conditions at **0°C. The two-speed motor is selected for direct transmission to achieve one machine with two uses (i.e. exhausting at ordinary times and exhausting smoke at high temperatures during firefighting), which has the advantages of excellent high temperature resistance, high efficiency, small size and simple installation (horizontal, vertical and lifting are all possible). It is usually applied to occasions with small air volume and high pressure requirements. It is an ideal energy-saving ventilation device, which drives the special curved blades to rotate with the shaft through the difference in air pressure between indoor and outdoor to discharge indoor air
