Free air?

diesel lover · Feb 8, 2014

I have to add this as it such an endless use tool! This is a gladhand attached to a air chuck. On a semi truck you attach the glad hand to the truck and release the trailer side only. You now have a air compressor!! It has a cutoff pressure of 110 to 135 psi. The truck has decent sized air tanks and a decent sized air compressor that is oiled by the engines oil.

Attach the glad hand to the trailer emergency brake side, attach any air tool you want through either a 1/4 or 3/8 air fitting. Easy to air up tires, use a die grinder or small air sander, air hammer or 3/8 impact. At idle I used this set up with 20 feet of air hose and my 3/8 impact wrench to change a flat tire on an SUV. It was limited air supply but really not bad compared a small portable air compressor. The lugnuts were torqued to 100 foot pounds.

So using a trucks air supply which is already produced while a truck is idling you can easily air up tires, or complete any small task.

I know some of you may not be familiar with large trucks but I knew you would find this interesting.

This is indeed one of the FREE air supply's out there as a truck's air compressor is producing air as needed while the engine idles.

Our small service station just last week shut off the outside air. The gas pumps have been gone for a long time. It has only been a week but I miss it badly. Stopped by to air up trailer tires when I find a new piece of junk to drag home. Have both gas and electric compressor at the house,but enjoyed the ease of use. I really feel badly but kind of feel like it is my fault for the owner shutting it off. 32 years of air that I know of- and it certainly was not free to the man that does car repairs and owns the place.

Many stations quit supplying free air because of vandalism. I carry an air tank.

The air isn't really free. Someone has to pay to run and maintain the compressor. Just surprised by how many here don't even have a small home AC...Shocked really. I have always had a 60gal upright 220v. I always saw it as an absolute necessity.

I'm looking to buy a house but don't own one currently. I grew up with a smaller compressor but it still did great for airing up car and tractor tires.

I was looking to buy a portable air tank but my friend sold me the 2 gallon CH compressor for 45$. Perfect for me! This is great until I have a place to put a 26 gallon or even 60 gallon compressor. Till then it is worth saving up the money for a larger compressor. There is no reason for me to buy anything smaller than 26 gallon for constant air tool use age!

My 2 gallon compressor is 120 volt, 2 amp or 240 watt. It could easily be powered off a 500 watt power inverter for airing up a tire in the middle of nowhere ! Just another reason I bought it.

I do have a friends house with an air compressor I can use anytime for vehicle repairs. I simply bring over my air tools and repair anything as needed.

i have the 60 gallon compressor in the shop and a wall mounted small 120 v unit in the garage. The garage unit is great for airing up mower tires, etc. would take a long time to air up the truck tires. Thats what the shop unit is for.

There may be free air, but there's no such thing as free compressed air.
I own 6 air compressors, and I've always got my eyes peeled looking for the next one. :laughing:
I bought one of these several years ago. Puma Twin Tank 12 Volt 2 Gallon Oil Less Air Compressor | eBay
They were cheaper when I bought mine, but if I lost mine I'd buy another. I don't go far without it. I've aired up log skidder tires with it, ran an impact on it, and it is indispensable at an auction (have you ever bought anything at an auction that had the tires inflated all the way? :laughing

It's not your ordinary pain in the butt 12v compressor.

Wow my 120 volt AC compressor is only 1/3 horse power and max psi is at 110. The price is right for me at 45$ used only once as I wouldn't ever have paid 100$ for this thing new.

I'm very familiar with log skidders and they have very large tires!! My friend ran a timber jack with a 4-53 Detroit 2 stroke.

I must know at this point if it can inflate tires that large and run air impacts what Is the max psi??
2 gallons of volume, 1 horsepower of build up but I would like to know the max psi! Didn't know this compressor can do so much but it sounds like such a great option for portable unexpected repairs
