The great cooling pad exhaust fan

Specifications

1.Summary:

The great cooling pad exhaust fan is the cooling principle of negative pressure ventilation that use of negative

pressure air convection.By the installation location to the natural inhalation of fresh air - door or window,it will

discharge the indoor hot gas to the outside rapidly.Any problem of poor ventilation can be improved.Cooling

ventilation effect can reach 90% 98%.For a 700m3(about 100m2) plant,one set exhaust fan exchanges the air

indoor and exterior 63 times (44000/700 m3),thus making it like directly setting up one family fan in every

position.As a result,the environment is kept nice nad cool.

2.Features:

(1)Stainless steel fan blade,galvanized sheet frame,no deforming,no broken,attractive and durable.

(2)Adopted CAD/CAM technology,high overall pressure.large air flow,low noise,stable operation,long service life.

(3)With the motor rotating,shutters open and close automatically,thus preventing dust and moisture.lt's the best choice for ventilation in greenhouse and plants.

(4)The protective net is single-sided,that is one side is protective net and the other is shutter.
