The organic solvent-resistant fiberglass extensive fan range for sewage deodorant, waste gas purification, pumping corrosive acid gas exhaust. The maximum operating temperature is 80 ℃ resistance to organic solvents glass blower housing, an inlet bell, impeller are pure glass, steel, completely changed the production process of traditional carbon steel lined glass. Enclosures and bolts metal framework covered with the overall molding approach, solve the bolt damage due to corrosion caused by the phenomenon. Fans with double base, without dismantling bolt, easy to maintain fan. Fan shaft seals do special seal treatment to prevent leakage of toxic gases. Safety requirements: structural strength, low vibration 1. ANSYS stress and RSR rotor dynamic analysis of whole units were strengthening security. (Other domestic manufacturers have not done this) 2. impeller balancing in line with ISO1940 specifications of 2.5MM \ S levels. 3. After the fan assembly in accordance with AMCA 210-85 test, vibration unit in line with ISO2372 specifications of 4.5MM \ S levels. (GB is 6.3MM \ S grade) A. integrally molding shell, increase housing strength (the outer membrane designed to improve the appearance) B. inlet bell shape using the loudspeaker, enhance the smooth flow field, reducing noise and loss C. inlet bell The clearance between the impeller and less than 5mm, reducing performance loss, and for the line contact, can reduce the crystals attached to the inlet bell. (Mostly domestic wind turbine over 5MM) high performance high efficiency, low noise and low vibration top margin fans, buy the rest assured
