The Stovebolt Site Forums The Shop Area The Tool Chest Pump head

Well the air compressor runs but won't get past 100lbs anymore. It was kinda shot 5 years ago when I got it as it used a ton of oil.

Where is the go to for new pump heads? Its a ingersoll rand unit. 150 psi. Wouldn't mind going to 175 psi

EDIT: I was just interweb sleuthing and see it's cheaper to buy a whole new compressor. What a waste. Maybe if I buy new I tie both tanks together.

Yep
Its a throw away world today, I'm not sure What you would gain by toeing them together.

Tieing the two tanks together would give you more CFM between compressor cycles. Our Mennonite neighbor who had a custom furniture building business used a 1500 gallon propane tank (propane truck body). He said depending on what he was doing, he only had to fire the compressor up a couple of times a day. I think that air ran the well pump, too.

Yep, two tanks would be sweet to have. Especially if it does not have any leaks.
But it does also depend on how much air you use in a day.
Myself, I don’t use compressed air very much, so it would be a waste of energy to pump up so much air only to see it slowly leak off over several weeks.

If you're doing a lot of body work with air sanders and/or painting with HVLP spray guns, all the tank capacity you can get is just barely enough. When I ran a couple of body shops, we were always running short on air volume- - - -not necessarily pressure.

All depends on what you need volume and air quality wise
Clean dry air requires more compressor than wet dirty air
Larger tank won’t make up for insufficient cfm at needed pressure.
It will help with clean and dry some if the air gets to cool in the tank some of the water stays in the tank.
Aftercooler helps with air quality as well.
Rotary or screw is the way to go if you need larger volume.
Champion, and Quincy make decent reciprocating compressors, eastwood has a rotary that is rumored to do ok.
Cheap whole unit probably isn’t as good as a good pump for what you have assuming it’s at least a 5 hp

I don't understand how the cost is the same or less to buy a pump switches electric motor tank all shipped somewhere vs just a pump?

Probably because they'd rather sell you a complete package than one of its constituent components...

Warehousing, logistics etc. Companies want easy money. It’s just a wasteful throw away society.

You might check eBay. I have had good luck finding stuff there.

I would at least look at compressors by California Air, they claim to be significantly quieter than most…
My Emglo and Debilviss are definitely in the “not quiet" category……and when mine fails ….

Had to hit the HD today for a new storm door and I see they have a compressor rated for 200 lbs psi 20 or 30 gallon. Less than 300. If I just connect the tanks I should be in business? If it only lasts 10 years I'm still ahead.

The combination of both tanks will be a benefit.👍

200 psi seems to be out of the ordinary, the tank is probably rated for that or higher but I doubt that the compressor "cut in" will be set that high. I think most of the oilless light duty units today are set around 125 psi. I have only seen 2 stage compressors climb to 175psi.

Put a manual shut off valve between the two tanks. That way if you are starting from zero pressure you could shut off the old tank and get the new one to operating pressure quicker.

I agree, but the paperwork said 200. Even if it is only 175 I would be ok due to the price. connecting the tanks should be easy.

Thought I was gonna hit a home run last weekend. When I was getting everything together to sell my 03 Ram I stumbled across the compressor I bought just for the flywheel as the 60 gal one which was given to me had a broken flywheel. Swapped the pump heads and nada no PSI's

Might have found a winner. HoBO Freight has a 175 psi pump head for $235. Going to snag one and see if it will fit into place.

30 years ago, I treated myself to a brand new Craftsman oil-less air compressor. I diligently followed the breakin instructions, running it for 30 minutes at no load (drain valve open) while spraying WD-40 into the inlet periodically.

I painted my school bus with it, primer and paint. Used it all the time. Then after I moved and opened my bike shop, it became the shop compressor where it runs every day. 19 years ago, I even built it a little compressor house outside the shop.

It's still going strong! This year I opened the cover and the wiring was all still good, and I had installed an angled out drain valve for easier use. I dread the day that it fails, because no new one will be as good.
