I cannot image of working without air tools. They are almost a necessity for wood or metal work. Here is my collection. The most important part of the aersenal for air tools is you air supply. The volume (CFM) require to run continously the most air hungry tool should direct which compressor to buy. The tool I use that requires the most CFM in a continuous configuration is the pressurized media blaster that requires up to 20 CFM. I tryed running this with two 20 gallon compressors and still they did not keep up. Based on a recommendation of a friend that had one I bought the Ingersoll Rand T30. One of the best purchases I ever made for the shop.

Air Compressor

Ingersoll Rand T30 1 phase

This is a workhorse of a compressor. I use it almost every day. At 14 CFM and a 80 gallon tank, it runs all my air tools effortlessly and without running continuously. I have a ingersol rand air filter and then a Motoguard 110 air filter on the main supply.
