120 PSI Air Source Kits come with a low amp-draw, 25% duty cycle, 275C VIAIR compressor mounted on a 150 PSI-rated 1.5 gallon air tank with 5 ports. 120 PSI Air Source kits come with a pre-wired 90 PSI on / 120 PSI off pressure switch. The 120 PSI Air Source Kit comes complete with a 1/4” NPT brass drain cock, 1/4” NPT ASME coded and certified safety valve, 1/2” NPT port compression fitting for 3/8” (I.D.) air line pre-installed. To use, simply connect the pressure switch to fused power, make a solid ground, and connect an air line to the compression fitting. The use of a 40-amp relay and an appropriately-rated fuse is strongly recommended to preserve the life of the pressure switch. Returns will be accepted if the item is unused, uninstalled, in the original packaging and in brand new con.
