extra Air Compressor

I know some of you carry an extra small portable air compressor.  Can a small 135# unit air up the tires to 100#  Thinking of investing in one as one around the house would be nice.
Do you have any suggestions as to size and brand to carry??.  Need light weight unit.

I have their 3 gallon 110 psi one and have not aired up tires with it but like it for everything else. I might get one of the ones listed when I finally leave home base.

We carry a small unit that came from Home Depot. It is similar in capacity to the Sear's unit suggested above. It will air up a tire. It develops pressures a bit higher than the main compressor on your coach. With an appropriate adapter, it will air up the entire air system on your coach.

Expect the accessories and connections to be very low quality. I had to replace the primary connection point for the hose because the O-ring failed and I could never get it back in properly. Replacing the connections and accessories is not difficult. They are available at an auto parts store.

I prefer to use the compressed air from the primary air system on the coach. It has been through the dryer and will introduce less moisture into your inflatable target.

You would think the unit that comes with the coach would air a tire to 100 psi but mine wont go beyond 90. If my knees would hold out longer it might but I doubt  it. Oh well 90 psi beats a flat.

dub. The engine air compressor has an adjustable pressure relief and it can be raised to at least 125 psi. This is where I had them set mine so that I can get 115 psi in my steer tires

Listen for the blast of air from the air dryer purge cycle. At that point the pressure in the system is at max. You may be able to inflate to as much at 110 psi when the system pressure is at maximum.

Horace's recommendation regarding adjusting the pressure may help as well.

Max rated pressure for our tires is 110 psi (cold). Based on manufacturers' charts and the measured weights on our axles, the recommended pressures are less than 90 psi.

We got frustrated driving across the US when time after time, fueling stations either had no air or air was out of order. The engine compressor does not do it for tires so decided to invest a little in aux air.

First we bought a contractor's 125 psi compressor off Craigslist for $55, then a "Big Bertha" 1 inch impact wrench from Harbor Freight on sale for $112. Will twist off a wheel stud if the nut won't come off. Then for most wheel nuts, a twin hammer 1/2" impact wrench for $59 on sale. To give both impacts the volume they need, I took an old stainless aircraft accumulator tank, welded a nipple on for the LD air hose and now we have the volume for either one. Might have to wait a couple of minutes after several nuts but no big deal. Have plenty of air hose in both sizes to reach anywhere, just start the generator and away we go. Only need a good back to get the spare tire out of the compartment. Good time to use that iPhone/Android app for AAA.

So, about $250 will give you enough air to do anything, even paint the beast.

FYI: typical lug nuts are max torqued at 600 foot lbs. a six foot pipe on a breaker bar only needs 100 lbs to loosen the nuts. "Big Bertha" will generate 1200 to 1500 foot pounds. AAA road service small cordless electric impact will remove most big rig lug nuts. I watched them do it on mine!

I was refering to the small 110 unit in the basement by itself . I've never ran my coach engine simatanious  (sp) with the small 110 for added volume...  When at home I have a large compressor in the shop that I top off the tires with when needed.... It's true.. even truck stops don't keep air at the fuel islands like they did back in the day... A person is better off having plenty air supply on board.

I purchased a 15 cuft power tank setup, fill witrh CO2, that is a couple years supply for filling your tires, or running a air wrench etc. not nearly as large as a proper compressor etc, give it a look.
It might fit some folks real good, cost me $15.00 to fill tank.

I, too, have a Power Tank and consider it a luxury.  But it has really saved me a lot of grief on a few occasions.  I fill mine up about once a year.  Finding places to get the tank refilled is not, however, easy and I've paid as much as $25 to get it refilled.  I would not be without it.  Having said that, I might be selling it in a few months.

I am mystified about the necessity to have an air compressor in addition to the on board air.
I keep an eye on my tires and check them with a gauge before each trip but rarely do I have to add air.  I run 110 in all of them and only a couple times a year do I find that they are down to 105 or so. I have reset my Governor to 130 and I am able to use the on board air if necessary.  Do I have unique tires or am I missing something in not constantly checking and airing up tires ?  If I had a tire that needed air more than a couple times a year I would get it into the tire shop quickly.

Gary:  I am just thinking of the time your might could air a tire to get to a service center if you picked up a slow leak.  I know you have the on board compressor but air requirements come in handy sometimes away from the coach.  DAN

Gary,

Other than a 3 flats in a lot of years, I agree that only normally have to add air a couple of times a year. I just like having it there for filling the big raft or using air tools in a location other than my home. I do like to be able to quickly add a couple of lbs in to bring it up to 110 without waiting for the compressor to cycle. Heading down Baja, I like to have it in case I have to put a plug in a tire and air it back up.

Through the years, I have gotten into the habit of leaving the wrenches in the box and grabbing the air gun if I can. Spoiled or too many banged knuckles.

Others with a compressed CO2 tank will take up a lot less space, do mostly the same job.
