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 Tobacco use fan, the fan can also be used as free exhaust fan later, 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 air to escape the fire stairs, 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 exhaust fan, so that stairwells, elevator hall in positive pressure (blowing state). Exhaust fan receipt inspection and preparation prior to installation as follows: 1. Open the front box exhaust fan should check whether the packaging is complete, intact, the indicators exhaust fan meets the relevant requirements, the fan itself The necessary parts and their companies. 2, with 500V megger between the fan housing and the motor winding insulation resistance exhaust fan maintenance, its value should be greater than 0.5 megohms, or deal with the motor windings for drying, when drying temperature must not exceed 120 ℃.
