How To Pick An Air Compressor For Your Woodworking Shop

Executive Summary about Air Compressor By Bob Gillespie

I settled on a 5" Dynabrade sander and Sears 3HP air compressor. Air sanders are aggressive and efficient. Soon there was another machine besides the air compressor required having large amounts of air in the shop: an Onsrud inverted pin router. As a rule of thumb, a 5 HP air compressor will power one air sander, a 7.5 HP machine will power two and a 10 HP machine will be needed for three sanders.

The type of electrical power required by an air compressor is another consideration. Large air compressors will all require 3-phase power but the 5 HP models come either way. A small compressor pump on a huge tank will produce no more air than on a small tank. All reciprocating air compressors throw out oil with the air they compress. Buying the wrong air compressor can be a very costly mistake.
