ShoeBox MAX - $494

TheShoeBox MAX Air Compressor is set for 4500 psi (300 bar) output. Because of the burst disks, the output can not be changed . The price is $494.00 dollars. Built-in Fan, belt drive and hardened pistons are standard on the MAX model. 


The ShoeBox MAX Air Compressor requires an external input of 85 psi (6 bar) from a typical shop air compressor (125psi for the Freedom8). We recommend one of the inexpensive oil free compressors available everywhere. This takes the place of the first stage in compression and allows us to produce the ShoeBox at a breakthrough low price.


How It Works

The air compressor has two pistons. They are very small by air compressor standards. The upper cylinder is 1/4 inch, the lower 1/8th inch in diameter. The small pistons allow us to use a small 1/3 hp, 110 volt, ac motor to achieve high pressure, but limits the speed at which you can fill a tank.

The ShoeBox Air Compressor is driven by a quiet belt drive system. A lever mechanism senses the pressure in the pistons and shuts off the compressor when the tank is full. The cutoff pressure is adjustable approximately 100-300 psi from the factory setting using the shutoff collar to adjust the spring tension. Most parts are user serviceable.

It's user servicable

The compressors wear parts are simple o-rings, plastic sleeves and bronze bushings. The unit can be completely rebuilt with common hand tools. See theExploded View Diagram or our rebuild videos on the Support page.


What you need in addition to the ShoeBox

The ShoeBox needs a supply of compressed air fed into it for normal operation. You will need an oil free shop air compressor capable of 85 psi and about 1 cubic foot per minute output (125 psi and 3 cubic fpm output for the Freedom10 model). Virtually all small compressors with a tank can do this. See shop compressor examples on our Support page.  You will also need to supply a hose from the male output fitting on the ShoeBox to the tank your filling. We do not supply the hose due to the large variety of tanks and fittings but you can find suppliers on our Links page.
