My neighbor was throwing out an old Craftsman 30 Gal compressor. He said the motor fried because he was using it on a generator. I originally got it just for the tank to add to my little 2 Hp 4 gal compressor for extra storage. It turned out that all that was wrong was it needed a new Capacitor, so now I have a twin cylinder belt driven 3 Hp 220 compressor, cost $20.00! So much more quieter than my old direct drive!

Is 8.5@40 psi and 10.25@90 psi good for heavy consumption air tools? What can't I use with it.... Making a list of all air tools to buy now that I have a compressor to run them.

 

Freebie equipment or almost in this case is a WONDERFUL thing!!!! Good luck with your acquisition. For home shop use almost any tool except some high power sandblasters can be used with that rig. Take the time to let the compressor catch up and have a cold one! Just remember one thing... Alcohol and power tools should not be mixed.

Are your production numbers backwards?

 

Umm, yeah opps.
Even though it's oil bath, I always go by the less than 50% duty cycle. Ironically, it is very quick to go from 105-125. I was using it pretty hard after I changed the oil. Blowing dust off of anything I could find. For every 4 min of intermitent use it would run for about 20-30 and shut off. The only bad thing is the regulator is bad. So I may either take it apart and clean it out or more likely by a regulator/water seperator and an automatic oiler.

On a side note about that regulator. it is built in, comes out of the tank into a cast aluminum Y where both tank and regulator gages are. The **** for regulator is below and the outlet is below that. air comes in from the bottom. Can this be fixed or replaced? I just hate things that don't work.

Thanks, Dave

 

I would not run a regulator at all. Remove the broken one. It is not necessary with most tools. For a die grinder you may want to run a regulator to limit no load speed. A paint gun may need a regulator.

As far as a central lubricator, -DON'T! See my gallery for a point of use lubricator to use on the tools that need one. Otherwise it just messes up your hoses and other projects with oil spatters. Those central lubricators (FRL in industry terms) are available but they should only be used on some pneumatic powered industrial machine. They have almost no use in a home shop.

The only thing you need on the outlet of that system is a large coalescing filter.

 

sometimes on the regulator you can just file the contact points to clean them up. Good find, I've been looking for a tank for my 4HP Craftsman. Guess I'll have to weld it.

 

Free overcomes many faults.

I agree, remove the regulator off the compressor.

What you do is buy a new one, and install two quick fittings, one make one female, and put that at the end of your hose, then clip your paint gun onto that. That's pretty much all you'd need a regulator for.

For tool oiling, oil the tools before you use them, and every once in a while while you're using them heavily. YOu don't want oil in the hose as should you decide to paint something down the road, the oil will cause fish eyes in your work.

A water trap/filter is an excellent investment. I have mine mounted off the side of the tank and as long as I remember to drain it once in a while, it's great.

Also make sure the valve on the bottom of the tank is free of goop and easily accessed. I extended mine as my tank is in a closet under a stair well, so I have a right angle fitting with a section of brass tubing, with the valve on the end at the moment. That's leaving later in the week as I got my voltage-actuated release valve, which means I'll be able to do this with a switch on the wall, thus not have to climb back there and bend over and hit my head on the bottom of the stairs, yet again.

 

yea, we don't want you hitting the bottom of the stairs with your head. you might hurt the stairs, and its a pain in the rear changing the treads.

 

That and all the nails hanging down lmao.
