 BF4-72-6C fan 
 F4-72 series fan is produced by the new national standard corrosion-resistant centrifugal fan, is a high-quality carbon steel for the frame to a specific technology for processing of glass fiber reinforced polyester composite production, it has all-glass corrosion resistance of steel fan and the structural strength of steel fan. The fan uses a wide range, low noise, smooth operation, is currently the ideal corrosion-resistant fans. 
 F4-72-type centrifugal fan for the carriage of not more than 80 degrees Celsius temperature corrosive gases, plant and buildings used for general ventilation, especially for exhaust gas purification tower and various forms of support used. Purification tower is the ideal auxiliary equipment. 

 Fan structure: fan impeller, casing, inlet, frame and other components. NO6C above with transmission. A type of impeller and direct-drive motor, C-style for the belt drive, D drive for the coupling type. Y series motor with homemade. Transmission also can create special user requirements. 

 1 After the impeller type for the wing, with high-quality steel plate as a skeleton, with a special treatment by a particular process of the special anti-corrosion layer of fiberglass. High strength, aerodynamic performance, dynamic balance by the second check, moving flat thin precision of 6.3 level, the overall dynamic change smoothly. 
 (2) the production of glass fiber reinforced plastic housing with the overall spiral structure. Back-surface smooth as glass, steel outlet resistance produced by the overall convergence type, by finishing in the chassis with screws after the entrance side, the elite are indeed high, the gas can smoothly into the impeller, flow resistance is small. 

 3 Transmission Group: A-type, C type, D type three transmission mode of the fan spindle are made of high quality steel, and corrosion must have a special anti-gas branch, simple structure and easy maintenance. 

 4 by the Q235A steel bracket welded to meet customers' specific requirements, in addition to the standard factory installed map production, but also manufacture according to customers special requirements.
