Factory Promotional Vacuum Pump - PAC Centrifugal Fan with forward curved impellers – Fair Sky

Description

The housing is manufactured in galvanized sheet steel, The houses are ormed by two side plates spot-welded to a central scroll. A cut-off mounted on to the discharge prevents turbulence. The side plates have an aerodynamic profile and include some drill holes to allow fixing of the base supports as well as the motor support.

The impeller has forward curved blades manufactured in galvanised sheet steel. All impellers are dynamically balanced.

Shafts are manufactured from C45 carbon steel using an automatic process for positioning and cutting of the keyways. All dimensional tolerances of the shaft are fully checked to ensure a precise fit. All shafts are then coated with an anti-corrosion varnish after assembly.

Bearings used are either deep groove ball bearing with an adaptor sleeve or spherical roller bearings sealed at both sides for different duty application.
