Top margin pharmaceutical laboratories dedicated fan blower extensive range for sewage odor, gas purification, acid corrosive gas pump drainage. The maximum operating pressure up to 7000Pa highest temperature is 80 ℃ top margin pharmaceutical laboratories dedicated fan fan casing, inlet bell, impellers are pure glass, steel, completely changed the production process of traditional glass-lined carbon steel. Enclosures and metal framework forming the connecting bolts coated with the overall approach, completely 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 poisonous gases. Top margin fan, saving perhaps first attracted you to the brand, but the quality is definitely moving your top margin fan quality worthy of trust. Today's integrity, tomorrow's market, acquired profit performance efficiency and low noise and low vibration top margin fan, rest assured to buy A. shell molding process as a whole, shell strength increases (outer membrane design, appearance look better) B. entrance bell use of horn shape, enhance the smooth flow field, reduce noise and damage the impeller clearance C. entrance bell again less than 5mm, reducing performance loss, and for the line contact can reduce the crystals attached to the inlet bell. (Mostly domestic fan over 5MM) D. increase annular reinforcing rib front cover, increase the intensity of the impeller, the impeller to improve the safety of the bottom plate (domestic impeller no reinforcing ribs) E. shell with screws pre-injection method, reduced maintenance of contact surface error, deposit positioning function F. Bell and the outer casing of the inlet plane to reduce leakage G. axis and the axis of the bearing installation protection, increased security H. motor to slide design is easy to adjust and transform horsepower F: impeller The most advanced design techniques triples, and for the pure glass steel production, (many domestic steel impeller fan with glass-coated steel production, easy delamination.) G: impeller base increased back ribs, can enhance the strength of the impeller, can also increase the fan shaft vacuum sealing portion, truly zero leakage.
