DEAR TIM: I’ve got quite a bit of painting to do both inside and outside my home. I watched a neighbor use an airless paint sprayer and he made a mess of things. It seemed to spit the paint out.

This compressed air machine really blows. In a good way.

Air compressors are some of the most crucial tools in a construction or rental business. These machines power a vast range of other tools, from nailers to pneumatic wrenches to paint and air sprayers.
