FRP Frame/Blades Cone Type Exhaust Fan

Features:

1. Principle of negative pressure fan: The negative pressure fan is designed according to the air connection and the principle of the negative pressure ventilation. The negative pressure fan is usually installed in poor ventilation places. When it is at work, it will force out the stagnant hot-gas, peculiar smell by using the negative pressure rapidly in the shortest possible time. At the same time, fresh air will be supplied into the door quickly and flow circularly, so as to achieve the aim of ventilation and cooling, and improve the workshop's environment.       

2. Low noise, steady operation, big air flow, power consumption: 0.75 kilowatt per hour.

3.Frame and blades are made of Fibreglass Reinforced Polyester, resistant to corrosion, acidproof alkali.

4. Direct type fan without maintenance, designed as a horn, do not need to replace the belt for maintenance.

5. The design of shutter system adopt the principle of air forward flow, which do not require electricity or manual switch for open and close, and can prevent entry of rain water.               

Application fields: almost all the places which required cooling or ventilation.
