Air multipliers

Any opinion on the air multipliers that Les Schwab (sp.?)sells.
They are around $500, are they a good investment for airing up coach tires or is there a better choice?

Thanks
Steve

Steve,

There are several quick disconnects on my bus that tie into the air brake system. Pressure there ranges from 120-130 PSI. I've setup a 50' hose with 180 degree tire chuck for inflating tires. This has worked well for me. I have no experience with air multipliers.

Hi Steve, They are pricy but they seem to work well. Some people install in coach and others keep them portable to use at other locations.

Some show up on e-bay for about half price.

We have the Les Schwab pump and like it very much. It will quickly air our front tires to 120# without having to start the motor and it's small and easy to store.

Thank you for the quick replies. Found another thread that I should have search first, sorry about that.
Since the Schwab units seem to work well, are there any other good alternatives for less money ie. the Viair compressors?

Thanks again

Just a quick question, Jim

Why would the front tires require 120 lbs. of air ? AL

That's what the placard on the coach and the folks at Les Schwab say they should be. I'm just the janitor that drives the bus, I'll leave the discussion about tire air pressures to others.
I can get 120 from the onboard system but it takes some time with the motor on hi idle to do it. This way we can top off with the air in the tank(s).
We have the portable unit and can help out others if they have an air source.

Just a wild idea to present, Jim.

When you get some time weigh your coach at your flying J for probably under a $10.00 dollar bill. Look over the tire inflation guides on the Michelin web site. Instead of riding on a park bench you can now enjoy your coach even more.
Just a idea from a guy in Missouri... FWIW

Hard to imagine anyone saying " I am just the janitor driving the bus " being a member of this forum.

I have the VIAIR 450 for about 250.00 and it works well also, and fits neatly in a travel bag. I inflate fronts to 115 and rears to 110. Barrie Boas 94 Concept 5111

Bought a never used one from a gentleman on the Escapees Forums last month and am glad I did. Am able to fully inflate all tires quickly now and can get 110lbs. easily. Couldn't get that before off my coach air. Used it for a friends tractor tire last week with 130lbs. pressure - handled it like it was a bicycle tire!
Having the doubler means I don't have to worry about finding a place to air up and can start out 1st thing fully aired up. It is very well made and solid, quality materials. Les Schwab makes a good product & I'm glad we got it. Ours is in a hard plastic case.

I have a campbell 110 volt that I bought at Wal-Mart that takes a little time so instead of $250 I will have a cup of coffee while I let it work.

I permanently installed the Air Multiplier in by drivers compartment bay and it easily inflates my fronts to 120 lbs.

Look on ebay. I found one for $80 used. It works perfectly. It is slow.

Jim,

Then forget multipliers. They are slow by definition.

The multiplier would be slow if you were filling a tire but for the 2 or 3 pound adjustments I make to account for temperature change when traveling south in the winter and back north in the spring it works fine. The thing I like is the fact that I have installed it permanently in the compartment under the drivers seat where it is out of the way.

The air multiplier that we have from Les Schwab is not slow - it actually fills the tires just as fast as the coach air filled my Jeep tires. If you're not in a hurry, keep an eye out for a used one on sale via Craigs List/Ebay or some other RV forum (like Escapees, etc).

Just a thought

I always run my engine when I use my multiplier some others have suggested they do not. I wonder if this has anything to do with the amount of air produced. I have a ViaAir permanently mounted in my Jeep and Via Air suggests running the motor to provide more juice to the compressor motor.

If your coach is like mine, a '95 Magna with Toyo tires, you best follow the placard in the front of the coach and run 120psi front, 110psi rear. Thats what I do, then check and adjust the pressure once a year, whether it needs it or not. Typically 2 or 3 of the tires need to have 5 - 10 psi added. Course I do a thump test with a heavy hammer before I start out so I know they are sound. I'd tell you how old my tires are but don't want to get into that discussion.

There is also the powertank system @ www.powertank.com. I do not have this product; however, I have been researching it and reading about its usage and it seems that it is quite an effective system for airing up your motorhome tires. The prices are somewhat steep. This is not an endorsement but just another option for consideration.
