Casing and Impeller for Centrifugal Blowers
Casing
- Casings are of mild Steel / S.S. 304/ S.S.316 / F.R.P. / M.S.R.L. of ample thickness and reinforcements, sufficient to preclude drumming.
- Casing shape is designed so as to obtain efficient pressure conversion.
- Drain Plug, inspection door and stuffing box can be provided.
Impeller
Open Type
Backward Curve
Aerofoil Type
Forward Curve
Multiblade Type
Paddle Type
- Impellers are fabricated from M.S. Sheets and plates.
- All Vanes are hand riveted and welded for long life.
- Clearance between impeller and the casing is so controlled, as to minimize air slippage, resulting in high volumetric efficiency and are accurately statically and dynamically balanced for smooth operation.
- Design of the impeller may be changed as per application.
