Garage air compressor
Posted on 10/20/26 at 8:33 am

Only used to air up tires and balls, nothing major.
Question do you leave the air in or release it every time you use it?
I release the hose air to roll it up easier, but realized today that I had 50 PSI on the tank from last use. Is that bad?

I leave the air in under whatever pressure is in the tank when I finish using it.
I've got an old pancake compressor that I've had for over 25 years and leaving the pressure in the tank has never harmed it in any way.
I will, from time to time, reach under the tank and release the pressure to rid the tank of any moisture that has accumulated, but that's the only time I bleed it dry.

I always drain mine so moisture doesn't build up, and I don't use it that often. Mostly on little woodworking projects for the nail/staple gun, and occasionally for airing up tires when the temp starts to drop. It only takes a couple of minutes for it to get running again. Plug it in and turn it on and then go look for whatever attachment I'm going to use on the hose. If it was something I was using a few times a week I might just leave it, but not worth risking it rusting out and failing when all it takes is a few turns on the valve to release the air.

Ok I did release it this morning and noticed some moisture in it. Appreciate the info.

I drain mine every time to drain moisture, those ball valves can corrode shut or, if you get really unlucky, the trapped water can freeze in the winter and crack them so you get a leaky valve. Just good basic maintenance with air compressors.

See that why I asked! never a dumb question is what we were taught, right?

By the next day it will have bled down to 0psi on mine anyway.

Another option is to just use a portable inflator, I have a little Milwaukee M12 inflator for tires and such, so much easier and more convenient that using one of my compressors. I can have the inflator hooked up and running faster than I can hook up a hose, tire chuck, and wait for a compressor to cycle up. I can set the inflator to a target PSI and walk away while it runs, no need to run a separate tire pressure gauge.

I don't empty the pressure out of mine but do drain fluid every couple weeks.

Are people still using compressors? I had one and gave it to my SIL who used for a while but has graduated to using more battery powered tools even for tire inflation.

I love the Dewalt tire inflator, it's too easy. If I had a compressor it would be for air driven tools, not tires.

I have the Ryobi 18V + One Tire Inflator. They have different models, and I use the smallest least expensive model and its pretty awesome. It's simple, very portable and easy to use.
Occasionally as needed, I'll take it and move from the garage (vehicles and hand truck/dolly), storage building (wheelbarrow), side parking area (kayak and boat trailers), and lakeshore (Jon Boat flip up wheels), and inflate all of the tires to the correct pressure on everything all at once.

Those battery powered inflators are great for occasional use but you’ll burn them up with routine use. I’ve gone through a lot of them with my small fleet of 3 vehicles, 2 of which have 80psi commercial tires, and employee vehicles. Even the dewalt and other brands. They are more made for bikes and occasional use like a flat at home.
Given that, OP I almost always let the air out but I can tell you that most guys that use them for work never do.
