Fast-Fill 200 PSI Air Source Kits come with a powerful, low amp-draw 380C VIAIR compressor mounted on a 200 PSI-rated 2.0 gallon air tank with 5 ports. All 200 PSI Air Source kits come with a pre-wired 165/200 PSI pressure switch. Both kits not only come with the industry's leading 200 PSI compressors but also come with a drain cock, safety valve, 1/2-inch 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. A 40-amp relay and an appropriately-rated fuse is recommended for use with this unit.
