Greenhouse Ventilation Fans

  • Features of Greenhouse Fans:

 
  1.  The fan consists of blades, motor, frame, protect net, support frame and shutters.
    The shutters open and close automatically when the fan starts and stops running, avoiding outside dust entering the room.
  1.  Frame of the fans: extra thick, galvanized steel sheet, one-off molded, high strength, anti-corrosive and durable.
  2.  Shutter, made of high strength galvanized steel sheet, flexible operation, dustproof and waterproof.
  3.  Belt tensioner, made of high quality aluminum magnesium alloy, avoiding belt loosening or dropping off, extending service life of belt and avoiding distortion.
  4.  Strict test criterion, consist of airflow test, noise test, libration test, drive concentric test, blade RPM test, whole machine efficiency test, dynamic balance test, the thickness of the galvanized sheet test, the size of the spare parts test, etc.

 

 

  • Main components and parameters of Greenhouse Fans:

 
    Blades are made of high quality stainless steel by CNC TURRET PUNCH PRESS, attractive and durable, special design of blade shape ensuring big air flow, no distortion ,no broken, passing the homeostasis test to ensure the air volume keeping the same as the very beginning during the operation life span.
    Siemens motor or Chineses famous motor can be chose, high efficient and energy-saving with CCC certificate. Protection class, IP55, insulation class, F. The voltage ,power ,frequency and phase can be customized.
    Belt impeller and pulley are made of aluminum magnesium alloy by injection molding, and pass through blast-sanding treatment for attractive appearance, reducing the weight of blade, high corrosion resistance, eliminating internal stress to improve its own rigidity and stability, high strength.
    The bearing adopts special waterproof design of double-row bearing, high intension, low noise, maintenance-free and long service life.
    Swung drop hammer is made of high quality nylon, stable performance, guaranteeing the shutters open and close flexibly.
