Frequently Asked Questions
Q: How much does it cost?
A: Currently the base retail price is 649 dollars. This unit has the mechanical shut off at a preset pressure.
Q: How fast will it fill a tank?
A: The latest F10 will fill a 68 cubic inch paintball tank (12.2 cubic feet) in a little more than an hour to 4500 psi.
Q: I hear it needs another compressor?
A: Yes, it needs compressed air input from an oil-free shop air compressor for maximum fill rate and to shut off at the designated pressure. The F10 needs 125 psi and the MAX needs 85 psi.
Q: What shop compressor can I use?
A: Almost ANY oil-free shop compressor that puts out at least 85 psi at 2 CFM or more will work fine. The Shoebox takes very little air and a shop compressor will only kick on a few times. Small shop air compressors are so cheap it didn’t make sense to try and build one into the ShoeBox. You should get one large enough so it will not run all the time.
Q: How many CFM does the ShoeBox compressor use when pumping?
A: It takes about 0.2 CFM which is nothing.
Q: Can I use a compressed air tank instead of a shop air compressor?
A: Yes you can. Some thing like a portable air tank for filling tires should work but it needs to be big enough to maintain some type of pressure during the fill time.
Q: Can I fill a scuba tank?
A: NOT for breathable air! Yes you can fill a scuba but you have to provide a fill hose and attachment fittings. It will fill an 80 cubic foot scuba tank to 3000 psi in about 24 hours.
Q: Can I use a low pressure scuba with a regulated output to 85 psi to feed the ShoeBox Air Compressor?
A: Yes but we don’t recommend it because a high pressure regulator is more expensive than a small shop compressor that can be bought new for 100 bucks.
Q: How much noise does it make?
A: Not that much but its not completely silent. Its about like your mothers sewing machine. The MAX model has a mechanical shut off that clacks when it gets close to shut off pressure.
Q: Does it turn off by itself?
A: Yes but the Max model is preset at the factory, the F10 is adjustable.
Q: What else do I need to get to make it work?
A: To keep the cost down we only supply a Foster style nipple output from the compressor. This is the same nipple you find on your paintball markers tank. You need to get a hose to connect what ever type of tank you have, scuba, paintball, pellet gun, to the compressor. And you will need a "First-Stage" Oil-Less compressor - some examples are shown on our site.
Q: What size is it?
A: Its about 16” wide, 12” deep and 6 ½ inches tall.
Q: Is there any water or particle filtration on the ShoeBox Air Compressor?
A: No there is not, to keep costs down. You can put a water trap between the shop compressor and the ShoeBox compressor if that’s a concern. See our Links page for customer setups.
Q: How much electricity will it take?
A: It will cost about 10 cents an hour to run the compressor.
Q: Can I put say 1000 psi into it to make it fill faster?
A: No not 1000 psi because it will overload the first piston and stall the motor. It will probably handle up to about 100 psi which will give you a faster fill.
Q: Will it be sold in Europe?
A: YES, we now have 220v 50 hz motors. Email us for details.
Q: Does it have a degas valve to disconnect the tank?
A: Yes, the knob to degas the line is directly above the output port. You screw it in to release the pressure.
Q: Will it be convertable from 3k to 4.5k?
A: Only the F10 model allows for adjustable shut off.
Q: Any safety features built in?
Yes, there is a standard replaceable burst disk built into the compressor. If your filling a paintball tank, there is a backcheck valve there, and two others in the compressor to prevent 4500 psi from getting back into your fill air compressor.
Q: What voltage does it take and can I plug it into a wall?
A: It takes 115vac so yes you can just plug it in the wall.
Q: Can I just top off a tank or do I need to drain it all the way before hooking it up?
A: You don't need to drain it. The compressor will start pumping from what ever pressure your at so you can top off your tank.
Q: Who is behind the design and production?
A: Tom Kaye owner of Airgun Designs is responsible for the development of the air compressor. He is getting back into the paintball business after 5 years in retirement.
