Detailed Product Description
green house ventilator fan ,
Outer frame is used advanced digital controled creased bend pipe reduction board machine,impacting processing industry, galvanized board, strong causticity resistance.
Special high intensity alloying wheel, more higher intensity than industrial, Nelon wheel, with fine ductile and long service life.
Auto-operated belt conditioner, it's not necessary to regulate during the service life of belt.
Newly twisted punch press blader, after the testing of dynamic balance and rest balance, ensures to cause a great amount of gas flow at the suitable blader shape, also noise has been well controled.
Louvered window is made of aluminum alloy, with special pneumatic open and shutting sructure to ensure the window completely open and shut,it can be in storm proof, rain proof and dust proof of carring belt rotary,which get the national patent.
Back safe net is easily dismounted
Eight strict quality testing procedures: noise, vibration, dynamic balance, rest balance, rotary concentric performance wind blader speeding, assembly efficiency measurement.
