Centrifugal shutter galvanized box fan
Centrifugal Push-Pull galvanized box fan belongs to the new generation of high energy efficient, very robust and reliable exhaust fans range, suitable for an extensive variety of professional applications in order to create optimal climate control system. This exhaust fan series consists of a 36/40/50” box fan. This centrifugal box fan has been designed, tested and developed in the our R&D laboratory, and serviced customer since 2003.
Its main function is ventilation and cooling. The exhaust fan is installed outside the workshop window to remove smelly gases, it is usually used in heat treatment plant, casting plant, plastics plant, garment factory, chemical plant, etc. Used in combination with evaporative cooling pad to lower the temperature of workshop, which can reduce the temperature by 8-10℃ while not compromising on the humidity, it is suitable for use in all kinds of textile mills, greenhouse, stock farm, storage and logistics etc.
Advantage of SinoGreen Wall Exhaust Fan:
- Low cost, low energy consumption
- Significant cooling effect
- Highair cleanliness
Main technical characters:
