Top margin pumping exhaust corrosion proof glass blower fan can be used in corrosive acid gases, gas processing purification, sewage odor, etc., containing corrosive gas environments. Details: top margin of corrosion proof glass blower has been the national explosion-proof certificate and certificate of high-tech products, the company is the star product, by the majority of customers. Fan casing, inlet bell, impellers are pure glass, steel, completely changed the production process of traditional glass-lined steel, carbon steel. · Chassis with hob connecting bolts coated with the overall molding processing mode, solve the bolt damage due to corrosion caused by the phenomenon. Fans with double base, without dismantling bolt, easy to maintain fan. · Fan seal at doing special seal treatment to prevent leakage of toxic and harmful gases. · Same fan efficiency operating point of the higher speed will be lower, as you improve the life of the unit and reduce the cost burden
