Forest River Grey Wolf 19RR Compressor Installation

My Forest River being a Toy Hauler there is always a need for high pressure air. For airing up tires to blowing dust and debris off motorcycles, tools and such.

I originally was planning on building a small 12V system using a portable air compressor I recently bought from Harbor Freight

For under $70 it is a great little 12V compressor.  I planned on adding a storage tank so it didn’t have to run constantly and I had a 10 gallon air tank in the shop I wasn’t using

But to be safe, I’d need to buy a pressure switch and other parts to make it all work….and after measuring, I realized it would simply take up too much room.

A bit of research let me to a company that sell a wide variety of self contained, portable 12V air compressing systems….VIAIR.

A bit more research on the 4X4 and offroad forums and I found a whole bunch of folks were using this model:

What’s in the Box
280C VIAIR compressor, 2.0 gallon air tank with a pre-wired 110/145 PSI pressure switch, drain cock, safety valve, compression fitting, pressure switch pre-installed and wired, mounting hardware (nuts, bolts, washers, locking washers), heavy duty mounting feet with vibration isolators, freeze-resistant wiring, direct mount air filter assembly (two spare elements), air line for remote mounting air filter, remote mount air filter fittings (2), heavy duty terminals (spade connector, ring terminal), check valve pre-installed in stainless steel braided leader hose, owner’s manual.

And for under $200 at the time of this writing (5-21-16) I think it is a bargain! Small, compact, relatively quiet and well built.

I decided to mount it in the trailer within the front storage compartment. I used a pair of simple tie down nylon straps and mounted it on a piece of semi-rigid foam to keep noise and vibration down

The straps allow easy removal for maintenance like draining the water from the tank and cleaning the air intake filter.

From the compressor I ran the hose to my electrical cabinet

In the electrical cabinet I mounted a regulator / dryer, on-off switch and a fuse.

A quick air disconnect on the outboard side of the regulator and I’m in business!

The hoses and air gun store with a VELCRO strap in the adjacent storage bay

It takes about 5 minutes to fill the 2 gallon tank and then I get about 25 “puffs” of air at 40psi before the compressor cycles again. Perfect for what I need.

I deflated the spare tire on the trailer and reinflated it to 65psi in only a few minutes. I didn’t time it, but it was well under 5 minutes.

A great little compressor if you have a need for air in a small space.
