    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!

    • Freedom8 Shoebox electric air compressor
    • 4500 PSI max working pressure

    • Machined dual rod alignment post for easy maintenance
    • 4 ft of air tube coils for superior heat dissipation
    • O-ring fittings prevent worn ferrules

    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:It does the job. The manual has everything you need to know.
    Things I would have changed:I would write the manual a little more clearly and step wise. I would put a lever handle of some kind on the pressure relief knob. Maybe a slide through like on a vise. I would certainly put an decent output pressure gage on a unit that costs this much. I would make it a little easier to change the pressure settings, and more clearly delineated. I would ship it set closer to its rated pressure. I am getting 4100 PSI fills according to the gage on my fill bottle.
    What others should know:It can be difficult to release pressure, and because its difficult its slow. If the check valve on your tank or gun counts on internal pressure for the best seal this means you will waste some of your fill each time until you can get relief valve open far enough.

    Things I liked:Good small Carbon tank and it looks to be good quality. ShoeBox compressor is great. High pressure hose works great. No leaks Good Uzi magazine no CO2 leaks. BB's are not foaling out
    Things I would have changed:Check valve was leaking and I had to polish surface of the valve to stop liking. I would suggest better quality control. Price is not competitive. You can get same size Carbon tank on Amazon for less but I do not know quality of those tanks.
    What others should know:Manual for the ShoeBox compressor is pure.

    Things I liked:No more pumping, reasonably quick and quiet (about as loud as a sewing machine) in refilling tanks. In fact, whatever you choose as a first stage to this will be louder. Customer support from the Shoebox main company is top notch, I had a few teething problems, both of which were solved quickly and without drama. Changing the fill pressure is pretty easy, I marked the pressure switch for 200 bar and 300 bar fills for easy switching.
    Things I would have changed:There is a bit of regular maintenance involved, but everything is explained very well in either the manual or online at the shoebox sight via videos. Anyone with a reasonable amount of technical ability will be fine repairing/maintaining the compressor. An easily seen outlet pressure gauge would be a nice touch, manipulating the rifle or tank while filling is an inconvenience at the least.
    What others should know:I found it best to use some tin snips to slot the front cover where the screws are. I simply loosen them now to slide the front cover off. I also used a tiny squirrel cage fan to cool the ac motor since it gets pretty warm after marathon filling sessions in the summer. For changing pressures I found a flat blade screwdriver hex bit is best for the task, use a scribe or a sharpie to mark pressures. For the price, this is pretty much a must have for any pcp air gunner; it's one of those tools where you wonder why you waited so long to purchase one after it's first use!

    • John from USA asked:

      Can I fill my scuba tank with this and the oil free compressor and if so how long to fill It

      • Jerry from USA:

        yes, scuba tanks can be filled at the rate of 8 cu ft per hour

    • Brian from USA asked:

      could I use a run of the mill pancake compressor and this to fill a Benjamin marauder?

      • Val from USA:

        if that compressor provides 100-125 PSI on the output then sure

    • James from USA asked:

      Can this be used to fill the Crosman Challenger PCP rifles? If so, what adapters (if any) would be needed?

      • Val from USA:

        Click on the PCP Hookup tab on the Challenger page and choose shoebox compressor to see if any adapters are needed!
