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.

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 Two cored openings are provided to allow circulation of air (except for gas). 4.3 Has cast fins to improve rigidity and increase heat dissipation 4.3 Labyrinth type oil seal. Oil passages are generously sized to allow optimum recirculation. 4.4 Has air vent and magnetic plug at the bottom of the oil reservoir.
