Spare Parts
The bearings are intended as spare parts. Commercially available stan-
dard parts are to be purchased on the open market. If an overhaul re-
quires parts other than bearings or standard parts your Busch
representative will clarify whether an overhaul is economic or a re-
placement side channel blower should be considered.
Note
: When ordering spare parts or accessories always quote the type
and the serial no. of the side channel blower (data on the nameplate).
