I have a Sanborn Black Max 22 gal. compressor Mod#B109BLR300-22SWC. The motor is a Magnetic/Century 3 H.P. 115v Model 8-165730-20 Ser# BF-532 15A-7.5 RPM 3450. It is missing the run and start capacitors. I have no idea as to what the motor capacitors part numbers are or their specs are so I can order the parts.

Sanborn/Coleman was bought out by MAT Solutions. A website I found lists Sanborn/Coleman compressors and parts but it does not show your model number. It does say, however, to email them with your model number and they will be able to find your parts for you. I have included the link for you here: http://www.mastertoolrepair.com/colemansanborn-portable-parts-freedirect-drive-electric-c-271_35_172_178.html

The starting capacitor on the motor I am working on (same as yours) looks to be an AerovoxM, part number 157695-51. Label on capacitor says it's 509 - 708 MFD and rated at 110VAC.

The running capacitor was missing. The telephone number for MagneTek Century Electric in St. Louis is no longer in service. However, I contacted MAT Industries, LLC (they absorbed Sanborn). They gave me the following information:


The running capacitor is P/N 166-0052. It's 20 MFD and rated at 370 VAC. Price: $54.12
