Centrifugal Fans for Indoor Ventilation of Large Buildings

The 4-14 series centrifugal fan is suitable for indoor ventilation in general factories and large buildings. 
It can be used to input gas as well as to output gas. 
The gas delivered by the 4-14 series fan should be no more than 80 °C air and other gases that are not self-igniting and are not harmful to the human body and are not corrosive to steel materials. No viscous substances are allowed in the gas, and the dust and hard particles contained in the gas are not more than 150 mg/m3. 
It has large flow and low noise, more use in building ventilation, ventilation and drying of materials, air purification and industrial waste gas treatment, industrial dust collectors, air purification and discharge in hazardous working environments(Paper production line, electrolytic aluminum production line, textile factory...). Blasting of boilers and brick kilns, transport of various gases, transport of granules/powders/debris/fiber materials, etc.
