DeWalt Air Compressors


DeWalt Air Compressors are sold at a number of specialty and big-box stores around the nation like Northern Tool and Sears. The DeWalt air compressors offering spans hand carried electric air compressors, stationary installed air compressors, wheelbarrow type gas powered compressors, and wheeled portable electric units.

They also supply some combo-kits offering compressors and air tools in one package.

The smallest DeWalt air compressor I've seen is a .3 HP hand carry compressor, and the largest is a 5.2 HP on a vertical 80 gallon tank.

They have a pretty comprehensive website. Interestingly enough their parts link leads to a ServiceNet page, upon which you can source parts for a number of different air compressors.
