Booster Pump

Yes, the ShoeBox is a compressor. It requires a "Home Depot" garage compressor to feed 75/80 psi to it which it boosts to 4500 psi and then turns itself off. Not sure if you're leading into doing the same to a Yong Heng compressor so I'll just add that the ShoeBox is designed to be used in that manner. Or buy a ShoeBox and a standard home garage air compressor. The one I have has been keeping 3 PCP's satisfied for 3 or 4 years. Good shooting... Buck in Willcox
