Centrifugal push-pull exhaust fan application

The negative pressure fan is a process that uses the principle of air convection, and the motor drives the blade fan to rotate, so that the indoor air is discharged out of the room, forming negative pressure inside the greenhouse, and the outdoor air enters the room under the action of pressure.

Centrifugal system open the shutters at complete 90 degree to ensure the lowest air resistance and biggest air volume. When close, the sealing can efficiently block light and wind into the poultry farm house. As the first one adopt high quality nylon PA66 to ensure the long service life. The fasteners of centrifugal system all are copper rivets, wear-resisting and no rust, flexible. Guide rod is made of 304 stainless steel, ensure the high strength, no rust, reduce friction.
