Air Compressors - Seeking Recommendations

I'm considering the purchase of an air compressor to place in my coach garage and to use for maintaining my coach tire pressure (along with other utility a compressor affords) and thought I'd reach out to the forum for recommendations on the type/capacity/brand to consider.

My thinking is I'll need something along the lines of a min. 125 lb capacity but don't need to over do it in terms of what I purchase.

Any recommendations will be appreciated.

Well if it's staying in the garage and you're not going to carry it with you I would go with something reasonably large so it can handle the demand and have the capacity of air driven tools if you are a DIY. That capacity and recovery may be something you'll have to research. For occasional use and a stand alone unit try looking at Harbor Freight, Sears or Lowes. Try reading reviews and research on Google.

Am I correct in assuming that you already have a portable compressor in your coach such as the Viair 400P-RV? Sounds like you want a permanently mounted unit to also run air tools, etc. These run near $1,000 and usually require 240V. Although they have a high CFM rating, max PSI may only be 125. How about something semi-portable such as the Ingersoll-Rand Garage Mate 2HP? Highly rated on Amazon and max PSI is 135 running on 115V. If you don't plan on using air tools much, then perhaps a cheaper pancake-type compressor will be adequate.
Although not an expert, it is my understanding that if you plan on running air tools, you will need at least 90 PSI with robust CFM rating.

I would guess you might have tires that run 110 lbs. pressure, or more. Try this Porter-Cable 6 Gal. 150 PSI Portable Air Compressor-C2002 - The Home Depot $99 on sale. Be sure whatever you get can have a cut-in higher than the pressure you need to set the tires at.

Without knowing much about your needs my thoughts are 125 PSI is too low. My compressor is rated for 150 PSI and it will BARELY top off my steer's that require 120 lbs. The unit below is what I carry in one of the slide out trays on the coach with 50' of hose.

All depends on your needs other than motorhome tires. Operating air tools? Do you want fixed or transportable (wheels or not)? Noise level? Space available? 120 or 240 volt available?

In the shop I have a 30 gallon wheeled upright unit. Oil lubricated so quiet (not the rattle racket that a oil less makes). It will operate nailers, impact wrenches, etc. And air up the motorhome tires. The low noise level is a biggie to me - oil lubricated and larger tank so it runs less often).

Next step up would be something like a 60 gallon upright, oil lubricated, 240 volt.

Suggest to watch Craigslist for a good used unit.

I have a older version of this unit from home depot. http://m.homedepot.com/p/Husky-30-Ga...302H/206695048

I have a 60 gallon upright that goes to 125psi, but it won't fill my motor home tires. Part of the reason is the hose length needed to reach my coach. You need to run large diameter hose for those big tires.

I have the Porter Cable 150 psi tankless electric compressor that stores in a bay and can inflate my 22.5's at a rate of 1 psi every 15 seconds. My coach is parked alongside my house and when I need air, I just use the portable unit. Between the power cord and air hose, I can reach all 8 tires by just plugging into an outlet in my center bay.

This is really a great compressor. It has a snap on chuck so you don't have to sit there holding it.

To be clear, I principally just want a compressor to periodically air up my coach tires which include the fronts running 125 psi. but on occasion may want to use certain air tools such as a small hand held buffer as I do my own detailing of both autos and the coach.

Thanks for the recommendations thus far.

I have this same compressor. Agree it's excellent for airing up RV tires. I added quick disconnects to the hose and a Milton air Chuck.

Note it's not tankless, it does have a small 1.5 gallon tank.

This one works good and will air up your front tires. https://www.lowes.com/pd/PORTER-CABL...ressor/4764588

If you want one to take along on the road there are some out there that don't take up much room. I started out with a small stand alone without a tank on it rated at 135 psi. I had to add about 10 psi to a tire on the road. It took about 20 minutes. I then bought a new one that was rated at 150 psi and had a small tank on it. That 10 psi took about 2 minutes. The 120 volt pump better and more handy than a 12 volt. My 12 volt had clips that I had to clamp on the battery. Not handy. If you have 125 psi in your tires I would go for the 150 psi compressor. Then you have to look at the cfm of the compressor, the volume it pumps. The more cfm the faster it will fill a tire. Then it is just a matter of looking at the ratings. Go to a place that sells a lot of compressors. I got mine at Menards on sale for a little over 100 bucks. If you go with a small one be sure to have a clip on chuck so you don't have to hold it too long. Holding an air chuck on a tire for 20 minutes is hard on your hands.

I second the recommendation of a 150# compressor. A 125 will cycle between 125 and 110 psi. You'll be forever putting 120 psi in steering tires of a large class A coach.
