JVF-AM-350E4 Side wall exhaust fan Axial flow fan with louvers

The JVF-AM side wall exhaust fan is driven directly by a low-noise external rotor motor and a forward swept axial flow fan blade; The square galvanized steel sheet metal shell has a thickness that matches the thickness of the wall, and it is more convenient to have reserved square holes on the wall. The air outlet is equipped with an aluminum gravity check valve, which has obvious low noise, smooth operation, good corrosion resistance, beautiful appearance, dust prevention, and natural wind backflow prevention. It can be equipped with insect proof nets and 45 ° rain covers according to the design and usage requirements.

The air inlet can be equipped with a fire damper (normally open), which is used to automatically close the valve body and chain notify the exhaust fan to operate in case of a fire, playing an auxiliary role in fire linkage.
