Q345 Backward Impeller Centrifugal Ventilation Fans Centrifugal Air Blower

Large Air Volume Ventilation Centrifugal Fan Q345 Backward Impeller

This series of centrifugal fans has high efficiency, low noise and stable performance curve. Mainly used for indoor ventilation, dehumidification and dust removal, etc. in factories and mines, stadiums, opera houses, basements, large and small hotels, restaurants, shopping malls and large buildings. It can also be used as a gas recycler with other types of machinery.

Fan Type
The fan shall be of the single-inlet centrifugal type with the backward curved steel wheel. The drive types shall be direct, coupling or belt.

Wheel
The wheel shall be of the backward curved centrifugal steel type and all welded. The wheel shall be statically and dynamically balanced up to ISO 1940-G4.0 standard. Stable airflow and low sound should be ensured as the wheel is operating at the maximum allowable speed. Drop in performance shall be avoided as the operating point moves up or down. The wheel shall be readily removable for cleaning or maintenance.
Fan Housing
The fan housing shall be constructed of steel and it shall be thick and strong enough to withstand the maximum operating weight of the fan. The housing shall be continuously welded and have an access door for removing possible foreign bodies.
Inlet
The inlet shall be designed in line with aerodynamics. It shall be streamlined for better airflow movement and efficiency, reducing turbulence and sound.

Impeller Type: Backward/Forward/radial blade
Driving Mode: Direct/belt/Coupling drivetrain
System Type: Single inlet type, Overhang type
