12 July 2021: Due to a flood at my home/shop, Harbach Electronics is closed until I get this mess cleaned up and all of the damage repaired. Effective immediately I will be closed for 30-60 days or how ever long it takes to clean up and repair the damage. All pending orders will be canceled and refunded via the method of payment. I am sorry for the closure but I have to get things repaired and cleaned up. I will be back but it will be a little while. If you wish to order Dean Jacobs racing gear, please email me at and send me your phone number and I will contact you and process your order.
You can still view products, but no orders are being taken at this time. Sorry for the inconvenience!

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.
