JL series centrifugal industry greenhouse cooling fan /draught fan

Product Description

1.Features of JL series centrifugal industry greenhouse cooling fan /draught fan :

(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.

(5)The shutters support bar is plastic and linkage is galvanized sheet.

2.Summary of shutter mounted greenhouse ventilation fan

The Galvanized Sheet Frame Industrial Exhaust Fans For Poultry Farm 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 (44000/700m3),thus making it like

directly setting up one family fan in every position.As a result,the environment is kept nice nad cool.
