FEATURES OF CONTINENTAL INDUSTRIE MULTISTAGE CENTRIFUGAL
BLOWER MODEL 031A
I - BLOWER HOUSING
The centrifugal blower housing consists of an inlet head with special feature to direct air to
inlet of first impeller and outlet head of special design to eliminate friction and multiple
intermediate sections. These parts are made in cast iron EN-GJL-250 (ASTM A48-35B) (for
I/O heads) & cast aluminium (for intermediate sections) according to rigid Continental
Industrie specifications, extreme care to be exercised in assembly of interlocking cast
aluminium intermediate sections and annular diffusers (baffles).
The entire assembly is securely held together actually with multiple tension rods which bind
the entire housing into a solid integral unit.

3.0 Intermediate section
3.1 Cast aluminium EN-AC-42000 (ASTM 360.1).
3.2 Each intermediate section is cast in one piece
4.0 Bearing housing
The outboard bearing housings are cast iron and bolted to the outside of the head sections
insuring cool operation of bearings.
4.1 Cast iron EN-GJL-250 (ASTM A48-35B).
4.2 Has cast fins to improve rigidity and increase heat dissipation
4.3 Labyrinth type grease seal
4.4 Provided with 2 tapped holes in the housing flange to act as bearing puller.
N.B.: When the inlet air or gas temperature is too high, we can adapt as option special
bearing housings with a water or air cooling system (technical drawing on request).
