So at one point or another my work ended up with a large Husky oil-less POS air compressor (we have a donut comp too, but no problems with it) This eff ing thing is so loud and vibrates so bad, I never liked using it. (Temporary till oil unit was fixed) The supply line leaked, fixed it, then leaked again. By that time I got my old reliable one working. The oil-less was thrown in a corner years ago.

Had some time at work today. Going to FIX what should have never left the design table. Might take me a week, but it should be better than ever.

Those in the know might notice right away that I have an air filter attached in this ^ picture. That's right, they don't come with air filters. This is the major reason they are so loud. I'm not sure if running a filter will harm it :rolleyes: but I am.

This is factory. Little plastic coupler pushed against the inside of the units cover. Free to suck whatever:whistle: it wants.

This is the supply line and cause of the leakage. The ends have cone/band style rubber "o-rings" inside the couplers to seal against the fittings. Because the unit vibrates so bad, these rubber piece shred themselves to bits. I've had to replace these two times in the few months I used it. My large twin oil pump also uses this getto setup but without the vibration it isn't a problem.

Gunna make up some adapters to run AN fittings I guess, not sure yet.

Here are the fittings. The one on the right is for the head and can easily be changed to whatever I need. The larger one on the left is for the tank and incorporates a check valve. This is something I'm sure I can't do without. So, the hardest thing to adapt to an AN fitting would be the tank fitting. This is as far as I've gone today. Lunch break is over lol.

Once I get a filter figured out, cut the cover to make room for the filter, and figure out the supply line.... I will have another air compressor. It was left for dead and really told to throw away. Thinking about piggybacking with my garage compressor for more air volume during those air chiseling sessions and late night sanding.

At the same time, only needing 15a for power, I wonder if I can get a inverter to run this puppy while at the campsite? Or even plug it into someone's generator.

Yes, these things need some fixin' even before you ever run them. A cool mod would be to get some extra copper tubing and put multiple bends in it to form an aftercooler. With the extra length and bends it will be more flexible then the simple 90* piece. Can't you get compression fitting to NPT adapters for the check valve and head?

You would need a really big inverter to start the motor. A good generator would do it, but probably not a low-speed inverter-type generator.
 
Damn, well at least the whole camp could be taken care of if there's power. The little donut compressors work great too but not for tools or a lot of tire fills.
 
Got the new hose and fitting on. Pumps up just fine. I'm waiting for the air filter housings to get here from eBay. I cut up the cover some to fit better and make room for the hose. Can't wait for the filter to get here, slap that on. It may be oil-less but I've made it possible to use and it's MINE! :) put about $50 into it and a little time, should be able to pay me back

What's the temp rating of that hose?

I love it when a little work and ingenuity brings free stuff.

I'd like to find one with a dead motor and mount the pump portion underhood driven right off the engine.
 
I was thinking just that very thing, both those ideas actually.

Hose temp = dunno, gotta check cause it gets super hot
OBA = you damn right I thought about that first :D Even thought about mounting the tank LOL

Just use a York. Much easier mounting, IMO. They are oiled, but when modded they don't have tons of blowby and are quiet enough.

copper lines suck. They crack when subjected to vibration...go figure that's what they would use...

The line on C-H comp kept cracking...had to ghetto up a other rig for it.

as soon as it ran I sold the p.o.s....
 
Yes, but the York has been done many times. And I've never seen a free one.
