Half the fill time of previous Shoebox models, the new Freedom 8 compressor fills at a fast 8 Cubic Foot per Hour rate. Also, this model includes a digital pressure switch that can be set to shut off the compressor anywhere between 0-4500psi. 4 feet of cooling hose keeps the unit running cool. Input pressure of up to 125 psi required for optimal fill rate. This can be supplied by a standard oil-free shop compressor. The Freedom 8 comes complete with upgraded cooling fan, quiet belt-drive system, and hardened pistons for strength and longevity.
