Impellers


Backward Curved Aerofoil Type
Backward curved Aerofoil has ideal Aerodynamic characteristics with maximum Design efficiency of up to 89%. It can be used for clean air or low dust concentrations for medium to high-pressure industrial applications. 4 different series for varying wheel designs allow flexibility in selection.
The double-skin airfoil makes the blades sensitive to abrasive dust and is to be used only for low dust loads.
With years of application-oriented experience and latest Manufacturing facilities, we manufacture these Impellers within close tolerances matching exact blade profiles using mechanized welding procedures. With welding distortion Management, maintaining minimal impeller run out before dynamic balancing, and with special handling of Impeller, Blowerfab delivers world-class fans and blowers for your Critical applications.

Static pressures up to 1500 mmWC
Temperatures up to 550 ℃
High Peak Total Efficiency up to 89%
Non-overloading power curve.
Single Width, Single Inlet (SWSI) and Double Width, Double Inlet (DWDI).
Silent in operation viz z viz other profiles for similar operation.
Very high Strength of Impeller for clean gas application viz a viz other profiles for similar operation.


Backward Curved
The single Thickness Backward Curved Impeller is highly Efficient and only slightly less Efficient than its Aerofoil Counterpart. It has ideal Aerodynamic characteristics with maximum Design efficiency upto 82.4 %. It can be used for clean air or medium concentrations for medium to high pressure industrial applications. 9 different series for varying wheel designs allow flexibility in selection. This Design is united for Harsh process requirements and is the most preferred choice for majority of applications.
