BEARING MAINTENANCE

REPUBLIC CENTRIFUGAL BLOWER MAINTENANCE SCHEDULE

RB800, RB1200HC, RB2400

Bearings are a greased for life design. Bearings are assembled in a clean room environment. Do not attempt

to grease bearings or your warranty will be void. If bearings fail in the blower housing, Republic recommends

changing the entire bearing cartridge with a new cartridge, impeller, and blower pulley. This assembly should

be balanced
