JSF-inclined mixed flow pressurized fan for underground garage pressurized smoke exhaust

The underground garage pressurized smoke exhaust system of the JSF-inclined mixed flow pressurized fan enters the impeller axially and flows out axially along the conical surface through the rear guide vanes, suitable for axial supply and exhaust systems with positive pressure in pipelines.

JSF-inclined mixed flow pressurized fan for underground garage pressurized smoke exhaust

The pressurized smoke exhaust of the underground garage with the JSF-inclined mixed flow pressurized fan enters the impeller axially and flows out axially along the conical surface through the rear guide vanes. It is a fan that is between axial flow and centrifugal fans, with the characteristics of large air volume, compact structure, and easy installation. It is suitable for ventilation and air exchange in civil buildings, shopping malls, factories, underground facilities in warehouses, and other places.

The classification of pressurized smoke exhaust in underground parking garages by the external structure is based on the following:

① Standard type (straight cylindrical structure, horizontal air inlet and outlet)

② Roof type (with a square foundation base and rain cap added on top of the standard type)

③ Box type (additional frame type soundproof box is added on the basis of the standard type)

④ Silencing type (on the basis of the standard type, additional silencers are added to the air inlet and outlet)

Classified by environment:

① Standard type (equipped with Y series motor, suitable for environments with non flammable, explosive, and non corrosive air)

② Explosion proof type (equipped with ExdIIBT4 or ExdIICT4 explosion-proof motors, suitable for environments with flammable, explosive, and non corrosive air)

③ Anti corrosion type (equipped with anti-corrosion materials, suitable for non flammable, explosive environments containing corrosive air);

④ Explosion proof and anti-corrosion type (equipped with ExdIIBT4 or ExdIICT4 explosion-proof motors, with anti-corrosion materials; Suitable for environments that are flammable, explosive, and contain corrosive air

According to the speed regulation method of the electric motor:

① Standard type (equipped with a single speed motor)

② Dual speed type (equipped with dual speed electric motor)

③ Variable frequency type (equipped with variable frequency motor)
