I am very interested in purchasing one of these 4500's. I was wondering if there is a way to fill a model M type air tank to fill HPA tanks. My question is, is there a way to connect this to the tank and have it maintain the pressure in main tank. The tank is twice the size of a scuba tank and it will initially be full, I am just wanting to maintain the pressure instead of having to purchase a full size air compressor that cost four grand.
