View Full Version : Portable Tire Inflator/compressor

08-26-2015, 06:57 AM
I couldn't find a topic on this although I'm sure it has been well discussed. I've been searching for a good portable compressor that will adequately keep my tires at the recommended 80 psi. The ones I've tried have failed (blew out seals) and the heavier duty tire inflators have bulky tanks. Anyone have a recommendation and a store name I can purchase one.

Viair - Amazon or search online.

I had a 100 psi unit in the front compartment, but difficult to get to 80 psi. Got a 150 psi Porter Cable pancake compressor from Home Depot - $99 at the time. Put in a 110V receptacle in the front compartment and the pancake compressor fits nicely - really works well for 80 psi in the trailer and pickup tires. I also make sure it's at 150 psi before I hit the road so that I can add to a low tire on the road without running the generator.

We carry a Porter Cable 135PSI

The Viair for RVs mentioned above. It will handle the pressures and doesn't need a 30 minute cool down. Also comes with enough hose to handle something the length of a Montana. It also has a gage and pressure release button. Comes in a nice bag.

Picked up a heavy duty version of the Slime 4026. It's worked very well on this trip, including taking care of our one tire's slow leak and topped it off at 6k altitude to 80 psi. It's small and lightweight. http://smile.amazon.com/gp/product/B005Z8HAUK?psc=1&redirect=true&ref_=oh_aui_detailpage_o07_s00

We also use the Porter Cable 150 since we use G614's and need to inflate to 110#.

Picked up our portable compressor similar to WaltBennet but is 150 lb pressure unit at Harbor Freight!

Have carried the 12VDC high volume one from Harbor Freight for years. Works for me and has its own carry case.

Viair is the way to go because it uses 12v not 120 ac which you won't have if stranded on the roadside. Not everyone has a generator. I just bought this Viair from Amazon.

Viair for us also. Compact and easily stored with all hoses and fittings. Absolutely no problem pumping the Big Sky tires up to 110 lbs.

I too have the Viair 400P-RV. Very good quality. It's a bit slow, takes a while to raise a tire from 70 to 80psi. I'd say 2-3 minutes but seems like forever when crouched under the slide. And it gets HOT. After doing 8 tires it was 30 minutes before I felt comfortable putting it back in its bag and after almost another hour it was still warm to the touch when I was showing it off to my son-in-law.

Forgot to mention, I followed the link from scott-pati and the Viair is $50 cheaper than I paid just last month from Amazon.

Thank you all. It sounds like there are a few to choose from. I'll finish up the research and should be good to go. I love this site! Have a great year

Are you running G614's or the Sailun equivalents on your 3402? If not you should. And if you are not running them now, you will in the future. The Viair (and the HF knock off) are convenient being they run on 12V. They take a while to get a tire up to 80 PSI, and will likely never raise a tire to 110 PSI. As the G614 and Sailun are 110 PSI tires you may as well get one of the 120V compressors that go up to 150 PSI. Yes, you will have to have AC or run a generator but they will do the job. The Home Depot one costs less than the Viair but takes more space.

I still have my 12V compressor but since I went to G614's I have to use my 120V compressor. I will make you a great deal on my 12V compressor.

Viair or Air Lift. They are both good and use 12 volts.
