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!

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.

Things I liked: Considerably easier to operate than a hand pump. And quite a bit cheaper than other (often larger) high pressure compressors. Its low volume capability is ideal for filling a gun directly.

Things I would have changed: Quite pricy for a small pump.

What others should know: Works well filling my PCPs (AirForce). I don't have one, but I would imagine filling a large tank will take a very long time with this compressor.

Things I liked: almost ready to use right out of the box, just lube the shafts a bit, connect hoses and the other compressor. took a 90 cu in tank to 4100 psi in less than an hour, when at 2000 psi the air venturi tank filled quickly. nice not to need to hand pump for my PCP items

Things I would have changed: gauge on the out line so you know if the line has pressure. larger fan, this one works but the shoebox could use a lot more cooling wind. thumb screws on the cover, so I don't need to find the stupid little allen wrench every time I lube the shafts.

What others should know: you will need the jumper hose (out line 4500 psi) to what ever you connect it to. be sure to bleed off out line pressure or you will get a surprise. to get to 4500 psi you most likely will need to adjust the pressure cut off switch, mine was 400 psi short of 4500 psi. according to the air venturi gauge (not sure I trust it much)

What others should know: I do not recommend buying.
