A labeled photo diagram of an air compressor, with arrows pointing to the hose connectors, pressure adjustment knob, pressure gauges, pump, motor, air tank, and drain valve.

When we purchased our 26-gallon air compressor, we knew it would have to be occasionally drained of condensation. But draining the tank with the OEM stopcock was a pain and a better device was needed.

The big advantage of air power is that each tool doesn't need its own bulky motor. Instead, a single motor on the compressor converts the electrical energy into kinetic energy.
