FEATURES OF CONTINENTAL INDUSTRIE MULTISTAGE CENTRIFUGAL

BLOWER MODEL

451

I - BLOWER HOUSING

The centrifugal blower housing consists of an inlet head with special feature to direct air to

inlet of first impeller, an 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 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 400, PN 10 (16”)

1.2 Cast iron EN-GJL-250 (ASTM A48-35B)

1.3 Minimum wall thickness: 13 mm (0.50”)

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: 13 mm (0.50”)

2.4 Can be supplied in various flange positions relative to the vertical centre line in

increments of 90° (option).

2.5 Has eight 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 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.
