Tire inflator

[Cindycruiser]

Any suggestions on a portable tire inflator that is not too large. Need at least 125PSI and enough CFM to inflate 295.80.22.5 in a reasonable time. 120 v or 12 v will work

I use a small pancake air compressor I bought at Home Depot. Just be sure to get one rated to 150psig.

Good Luck.

Take a look at these. Light and ease to use. Will inflate many 295/80/22.5 tires 7 to 10# before it needs refilled. Info on site will confirm how many tires it can inflate, normal use it should last a few years.

Ditto. Mine is Craftsman, but same deal. You may find that the regulator tops out at 100 even if the compressor goes to 150. On mine, I just re-plumbed it and put a quick disconnect between the output and the regulator. That way I can run it with the regulator for bicycle tires and my paint sprayer, but pull the regulator off for use the with the MH tires.

Sears, Lowes, Home Depot have nice pancake compressors. Don't bnother with a 12v system as they are way too slow. You can always use your genny to get the 110v you need.

I put this one in my compartment with 110 volt plug.

I adjusted the pressure switch to 140 psi, it works like a champ, and I find more and more uses for it each trip.

Blowing out my grill, bicycle tires, sports equipment, Pool toys, etc.

A compressor can be very useful aside from inflating your coach tires.

I liked it so much I purchased another for my race car trailer.

I have a new Viair compressor on order from Amazon:

Amazon.com: Viair 40047 400P-RV Automatic Portable Compressor Kit: Automotive

It's a little pricy, but from everything I've seen online, it gets very good reviews, comes with everything you need to inflate high-pressure RV tires, and looks very compact. I can report back with more info after I get to use it this weekend (it's scheduled to arrive later this week)!

Take a close look at that Viair - it has a 33% DC rating
Depending on your needs it might not work for you

I use the 100% DC version a bit more $$ but well worth the extra expense
Had it for 5 years now - hard mount with a 5 gallon holding tank and three regulated outlets - Yes they are very good quality units

[Cindycruiser]

Let me know how that one works out. Sounds good

The first one I got was an inflator. It is just the compressor and no tank. I had to use it and took about 15 minutes to go about 10 psi to get to 90 psi in the tire. It is 110 volt.

Since we were going full time I wanted a better one. So I got this one from Menards that is a Fini Air Boss. It is 1 1/2 hp 110 v AC. I aired my tires getting ready to head out and it was very fast. It is bigger, but a lot faster. It has an adjustable regulator and a quick coupler so you can connect other air tools. It comes with an inflator hose with a quick snap on air chuck which I can't use on the outside duals. It also comes with a regular air hose that I put my dual foot air chuck on. That doesn't bother me to hold the air chuck on it because it airs so quick.

@KJINTF,

Not sure what the "33% DC rating" and "100% DC rating" mean... can you elaborate?

Thanks!

Take a close look at the product's user manual suggest you read the fine print related to use time and down time aka cool down requirements and the operating temps for the unit - heat destroys things very quickly

Duty Cycle all comes down to heat dissipation - and motor / compressor burn up aka FIRE - If you intend to let a compressor just fill a 100psi tire many times it takes 10 minutes or more. Again download the user manual on the specific motor/ compressor combination you are considering - a DC rating of 35% means it can NOT be run long before it will self destruct (check the warranty it is NOT covered under that circumstance) your 10 minute tire inflation turned into a nightmare and cost extra $$. From what I have seen this is the reason for the majority of low cost low DC motor/compressor failures. Stay away from the Quick Air III 12 Vdc units they can easily start a fire

For me unless it's 100% DC and operating at 80F for long periods rated it's NOT for me - but to each their own

KJINTF,

Interesting. Never knew about duty cycles before. Makes sense, though. These little compressors certainly have to work hard to inflate these big tires.

I'm not too worried about the cycle time on the Viair I have on order... I only ever need to add a few psi to each tire at a time (I check them regularly). I never inflate from flat (or very low), so duty cycle shouldn't be an issue for me.

Good to know, though!

And as a full-timer, I've got limited space for any new "toys" Anything much bigger than what I'm getting and I won't have room for it, LOL!

Thanks!

You may not be interested but RV Geeks has 2 UTube videos of a system they devised to use your coach air tanks and a line. I tried it and it works. You can buy the supplies and build it yourself. Try to Google tire inflation (or similar) by RVGeeks.
