Anybody ever hear of doing this?

Bankdude

Nope, but interested to hear if anyone else has....

Never used or heard of it. Do any of the major bag manufacturers recommend it?

That page is actually out of my AirLift instructions for the wireless control setup. I am not using AirLift bags.

Probably not a bad idea.

Compressed air will have moisture in in from the act of compressing it. I doubt it would have enough moisture to cause a freeze up problem. Waste of money in my opinion.

Ice Road Lisa does this all the time.

The bag won't freeze up, but any fill/dump valves may, as well as lines. I had a 1/2" line on my International from the compressor to the tank, and in real cold weather it would freeze.

I don't think adding something to keep anything from freezing will hurt anything. There are alcohol systems made for this purpose that are pretty cheap. I didn't read the pdf but I wonder if they're marketing their own brand of fluid and it's a way of making continual sales.

IRT drivers add alcohol to prevent freezing of important valving (like brakes & air ride height valves) as the compressor raises the temperature of the air and then it cools as it moves down line. This process causes excess moisture ( condensation) which becomes trapped in cold areas like valves. Unless you are continuously adding hot compressed air to your system in extreme cold climates you will do more damage than help to the system. The problem with alcohol is rubber components dry out at excelled rates and they will fail prematurely. People in the north in extreme cold use alcohol to combat the problem but prefer methods like tank drains that are automatic or manual to prevent moisture build up. Truck compressors cycle continuously as air is used in every brake application, air bags on your truck only get iar added when needed.

I think my Firestone bags had one of those added warnings about this as well. I had planned on doing this in the summer while I'm home ..... I'm going to be spending A LOT of time underneath it for some upgrades to my onboard air and redo the install of my Wireless AIR system.

Installed some PacBrake bags on a 2500 Cheby yesterday, poured 3-4 oz of this in... let's see what happens. Has no odor at all, has methanol as main ingredient.

She wouldn't make a pimple on a truck driver's butt. Just my opinion.

Modern air systems don't like alcohol or any other drying agent. It drys out any rubber o-rings and gaskets, causing problems later.

All class 8 trucks have an air dryer that removes the moisture before it gets to the components down the line.

I'm not a trucker, but I spent many, too many months working at -20 to -50 degrees below zero. Things that are not a problem at -10 DO become critical at those temps. Rubber seals are not even used there, a totally different polymer is in those systems and yes, there is a dryer - and if you count on it doing the job, you will be on the side of the road with brakes locked up.

I was in Little America. I understand the Daltin Rd is a little warmer, but not much. I'm in Florida right now and never, ever, ever want to be that cold again. My hats off to anybody who's willing to go there.

i've drove truck hauling machinery in the winter and all of you that don't think you need air line anti-freeze need to pull your head out of you a@# just my opinion. another thought i had is that Lisa can probably out drive any of you any day of the week that are talking s#$%
