Exhaust fan can also save power exhaust fan is a fan of good goods, when the quality of referral walks in 280 ℃ continuous mission time 30min, and cooled to a temperature in the dielectric quality of the still continuous running. But as our power has been reduced, we constantly improve conservation, exhaust fans can be more effectively save energy. Low-noise axial positive pressure blower Description: Low noise axial positive pressure blower: it can be used in metallurgy, chemical industry, light industry, food, medicine and other places civil ventilation or strengthen cooling purposes If the cabinet to remove row later smoke fan, the fan can also be used as free, can be installed in series in a longer interval of the exhaust duct, to increase the pressure in the pipeline. Positive pressure blower is pointing escape corridor air supply fan. It outdoor air pressure into the interior. When the building is on fire, it will produce a lot of smoke, carbon monoxide and other toxic gases and block the line of sight, through positive pressure blower to escape the fire stairs air exhaust fan maintenance, indoor smoke can not reach the stairs, to create conditions for people to escape. Positive pressure blower is typically mounted on top of the building, and the layers of the positive pressure valve linkage. Initial fire damper open, start positive pressure blower, so stairwells, elevator hall in positive pressure (blowing state).
