FM-220 Replacement Fan & Motor


SKU: FM220 Category:


The FM-220 is a direct replacement fan motor for the Heathkit SB-220 & SB-221.  The motor features “oilite” bearings for quiet operation.  The motor is rated at 30% greater RPM than the original so it moves a bit more air than the original fan.  This new fan motor is the best defense against tube failure due to overheating.

NOTE: Although the fan is injection molded to tight tolerances, it is advisable to balance the fan blade before final assembly. See FANBALANCE document in DOWNLOADS section for details.
