Description: GWS-II axial fan high temperature and moistureproof axial flow ventilation fan is one of new generation low noise axial flow vetilation products. This ventilation fan is designed by optimize aerodynamics theory and produced by advanced process technology, the structure is reasonable firmly, useful and safety, has the features of strong wind power, high pressure, low noise, low energy consumption and ligh weight.in the same install location, this ventilation fan can operates in foreward and reserved directions, and that the wind volume of foreward air outlet and reversion air outlet is the same. The angle of fan blade can be adjustable subject to the air outlet requirement. According to the difference of the diameter of blade impeller, there are 11 models from 4# to 11.2#..each fan has 8-12 pieces fan blades, there are 15-40 acupoints for the blades, max wind volume is 70000m3/h. This seriesaxial fanis equimped with high temperature resistant motor, can run under the the temperature blow 150°C. The blades are made of low magnesium aluminum alloy, has the performance of explosion-proof, after equiped with the explosion-proof motor, the ventilator fan can transport inflammable gas, it is ideal ventilation fan for cold chamber or dying store.
