FEATURES OF CONTINENTAL INDUSTRIE MULTISTAGE CENTRIFUGAL
BLOWER MODEL 400A
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)
according to rigid Continental Industrie specifications, extreme care to be exercised in
assembly of interlocking cast iron EN-GJL-250 (ASTM A48-35B) intermediate sections and
integral annular diffusers (baffles).
The heads are provided with integral mounting legs and rugged tie-rod lugs. The entire
assembly is securely held together actually with multiple tension rods which bind the entire
housing into a solid integral unit.
1.0 Inlet head
1.1 Flange connection DN 450, PN 10 (18”)
1.2 Cast iron EN-GJL-250 (ASTM A48-35B)
1.3 Minimum wall thickness: 8 mm (0.30”)
1.4 Can be supplied in various flange positions relative to the vertical centre line in
increments of 90° (option)
2.0 Outlet head
2.1 Flange connection DN 350, PN 10 (14”).
2.2 Cast iron EN-GJL-250 (ASTM A48-35B).
2.3 Minimum wall thickness: 8 mm (0.30”)
2.4 Can be supplied in various flange positions relative to the vertical centre line in
increments of 90° (option)
2.5 Has six integrally cast reinforcing ribs surrounding the volute contour and joining up
to the bearing housing mounting face for strength and to minimize vibration.
2.6 Has pipe connection to vent balancing piston leakage to inlet.
3.0 Intermediate section
3.1 Cast iron EN-GJL-250 (ASTM A48-35B).
3.2 2 Each intermediate section is cast in one piece
3.3 Each section has twelve evenly spaced integrally cast ribs for increased strength.
Increased surface area allows for proper heat dissipation.
