Freedom8 ShoeBox Electric Air Compressor, Max 4500 PSI

All the bells & whistles, 1/3 the price!

A small shop compressor acts as the first stage and feeds up to 125 psi of air into the ShoeBox (oil-free shop compressor required). It must provide at least 125 psi output and deliver 2-3 cu ft per minute at 125 psi. Most medium or large oil-free air compressors are adequate for this. The shop compressor does not run continuously. It kicks on only a few times during a small tank fill.

You'll need a hose to connect the shop compressor to the ShoeBox. A 4,500 psi hose with a female quick-disconnect fitting is needed to connect to the ShoeBox air output. The other end of the hose needs a fitting/adapter that fits the air input for your tank or gun.

The Freedom8 ShoeBox air compressor is a very compact, lightweight unit that's considerably less expensive than any other high-pressure air compressor currently sold. Imagine how convenient it'll be to have your own source of air, filling tanks and gun reservoirs, instead of using a handpump or running back and forth to a store.

The unit requires little maintenance and has relatively quiet operation. In fact, you'll kick yourself for not buying this sooner because it's easy to use. Our tech department tested a unit and found that it fills at the rate of approximately 0.11 cu ft of air per minute. You should be able to fill a 1000 cc tank from 0-3000 psi in about 1 hr.

This requires a shop compressor. The Freedom8 ShoeBox compressor is actually an air booster. You need to hook up the shop compressor to the Freedom8 ShoeBox and put 100-125 psi air into the ShoeBox. This joint effort delivers faster fill times.

This compressed air should not be used for breathing!
