Efficient Energy-Saving Backward Curved Industrial Boiler PA Boiler Fan




The Efficient Energy-Saving Backward Curved Industrial Boiler PA Boiler Fan centrifugal Fan can be used for indoor ventilation in general factories and large buildings.

It can be used as both an input gas and an output gas. The type of gas transported is air and other non-self-igniting, non-self-explosive, non-surrounding, harmless to the human body and is non-corrosive to steel materials.

It can also be made into explosion-proof and flame-retardant type according to the requirements of use. It is suitable for occasions with flammable, explosive and corrosive gases.

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. The gas temperature does not exceed 80°C, and similar gas properties are also available.

Can be widely used in factories, mines, stadiums, theaters, basements, large hotels, restaurants, shopping malls and large buildings for ventilation, cooling and dust removal, etc, it can also be used as a gas cycle with other types of mechanical equipment, the primary transport medium is air and other gases that are not self-igniting, non-self-destructing, harmless to the human body, and non-corrosive to steel.
