Great On-Board Air Kit
By J. Thomas
This Viair tank kit and the 450c compressor makes a great air system and includes everything you need to get started. I installed this system with a second 2.5g tank on my '95 F250 to deliver air to air fittings behind the front and rear bumpers, and to drive a Wolo Chief air horn. I did not use the included switch/gauge panel or the plastic tubing, the gauge panel is good heavy metal but I couldn't find a decent place to mount it without it looking like an eyesore. I used copper refrigerant tubing instead of the plastic tubing, hopefully it'll be more durable.The compressor and two tanks, mounted to a custom metal frame, fits cleanly up under the truck bed forward of the right rear tire (it's amazing how much room there is up there) and is not visible unless you get down under the truck and look up. I think if I had to do this a second time I'd probably use two compressors in parallel instead of one to make the tank fill time faster. As it is with one compressor and two tanks it takes about 5 minutes to fill the tanks to 150psi. Five gallons is not a lot of air, so when airing up large tires the compressor needs to run for quite a while, two compressors would make much quicker work of this.The pressure switch uses a trigger wire to power its internal relay, so you can run a wire up to a switch in the cab to enable/disable the compressor. I used a SPDT switch with one pole wired to constant power and one wired to accessory power, so I can leave the switch in accessory mode most of the time but switch to constant mode to let the compressor run with the truck turned off, or in the center-off position to disable the compressor. I ran a second wire from the pressure switch's output connection up to the dash to connect a LED to show when the compressor is actually running.My only complaint is that the included pressure switch is apparently intended to be screwed directly into the tank, but it seems to me this makes it too susceptible to getting hit and broken off. There are no mounting points or bracket, and it is an odd shape so it's not easy to mount it to anything. I ended up just tie-wrapping it to the metal frame I made to mount the tanks and compressor to the under side of the trunk bed.The included yellow air hose and fittings are fairly cheap, you'll probably want to use higher-quality products if you expect to use this stuff often.I added a second tank:Viair 91025 2.5 Gallon 6 Port Air Reservoir Tankand a Wolo Cheif air horn:The Chief Air Horn By Woloalong with an electric solenoid (JC Whitney item# ZX492214Y, couldn't find it on amazon) a SPDT heavy-duty switch and a 12v panel-mount LED to mount on the dash.
