No Lubricating Oil Air Compressor

[Spongebob89]

Hi,
do you have experience with no lubricating oil air compressors? Are good about durability and efficiency?
I saw this compressor to a detailing shop and the sound of it was quite smaller than my ABAC oil air compressor and also the time where the tank 100liters was refilled with air was 1-2mins (if I remember right).

Auarita no lubricating oil air compressor, oil less air compressor manufacturer, self-lubricating air compressor exporter, China silent no lubricating air compressor,

Oil Free Compressors are very common and are generality less expensive, but are generally considered to be acceptable for home shop and very light industrial use. I am on my second one, the first wore out after 20+ years of hobby shop use.

I expect that my present compressor will still be useful when my heirs eventually clean out my shop.

I've had mine for 12 years. Awesome compressor.

There are your run of the mill oil free compressors that are loud enough to keep the neighbors up at night and there are the more modern quiet ones. Which are you looking at?

I have a California air tools and it's great for what I use it for. I wouldn't try sandblasting a car frame with it though.

They're fine for occasional use but don't hold up well when used a lot.

I've had the same Craftsman one for 25 years. My usage is very light--aside from air hammers, inflating tires, and blow guns I don't use air much anymore in my garage.

It's LOUD. So loud I don't want to be in the garage without hearing protection when its running. When it dies or I buy a sandblasting cabinet I'll upgrade to something more substantial, and for the love of all things holy, quieter too.

The CAT compressors are nice ! Quiet (compared to all other air compressors). Reasonable amount of air (CFM).

The do NOT use the typical Teflon coated piston that the other styles do.

I got a tank from one that the pump blew up.

I put my 30 year old oiled pump on there.

That should tell you something

"Blew up". Ok.

"Blew up". Ok.

Didn't pump air. Don't know anymore, don't care. Tossed it in the scrap pile. I only wanted the tank.

I'm a moderate home garage user, have had my craftsmen oilless for 20ish yrs now I think....it hasn't let me down yet, but it's use is less these days with battery tools.

If you used it daily, you'd be wearing one out often.

My first Craftsman horizontal oil free reed air compressor is easily 35 years old. Approx. 5 years ago I rebuilt it, piston, sleeve, reed replacement. Thanks to GJ and @The Cobbler it was a total success, I didn’t even realize a repair was possible. Since the original purchase of the craftsman unit I have purchased 2 smaller oil free and a 80 gallon single stage.
The original Craftsman is now at the lake in semiretirement. And works just fine.
My buddy had a similar unit and decided to start it up in the winter in very cold conditions that didn’t end up well. Plus he didn’t know it could have been rebuilt. Can you say scraper?

I had a good size portable oilless compressor years ago and it kind of sucked. It was a craftsman with a 35 gallon horizontal tank. It was so loud it would drive you from the room.

If you look at the piston and connecting rod in it, it’s one piece and there is no wrist pin and it actually rocked side to side on the ends of the stroke. This action actually ruined the cylinder in it and made it oval. The cylinder was simply a coated aluminum sleeve that was open on the bottom.

The manufacturer did know there was an issue as the replacement cylinder was chrome lined steel and also had an inside flare on the bottom to strengthen it to stop it from ovaling again.

I would not call it durable as I rebuilt it 3 times. During its time I had to replace the valve plate twice and the cylinder and piston ring once. The piston ring is basically a piece of some form of gasket paper.

It was working when I sold it simply because I fixed it. The 30-40 gallon oiled compressor that replaced it has never been worked on. Not sure of the tank size of the replacement and it's also a vertical tank.


I also still have a Campbell Hausfield "professional" pancake oilless compressor in my shed but it is seldom used except to air up lawn mower tires. In comparison to the Craftsman it’s a nice unit. It spins at 1/2 speed in comparison and is substantially quieter. I wouldn’t use it as a primary compressor for a shop but it's nice to use a blow gun and inflate tires.

I'm happy to hear that some oil free compressors are doing well in light, homeowner use conditions. I just bought a Northstar 8 gallon oil free to replace a 50 year old John Deere A75 that finally gave up. This is my first oil free compressor and it's kept in attached but unheated garage. It's above freezing in there except for the coldest days but is starting an oil free compressor in cold conditions a problem? Is there a rule of thumb for minimum operating temperature?

I have that exact same workbench in my garage that I built when I was like 14. I bet we followed the same plans. I saw them in a home improvement book. Yours is slightly fancier as it's stained and has metal angle brackets. Mine used glue and wood dowels

That JD didn’t owe you anything, 50 years of service it earned its place in the shop. I wish my Craftsman had been a vertical model, less floor space required. It all adds up and we never build our garages big enough so every square foot helps.

Sounds like the same bench. Built mine when I was in junior high from plans in Reader's Digest Complete Do-it-yourself Manual. Mine also has dowel and glue construction but was later reinforced with the angle brackets. I have replaced the top once since I built it. Like my old Deere compressor, this bench is now 50 years old. Still works great.

I should RTFM more before I post. Straight from the book...

The ideal operating temperatures is 40° and 100°F (4° and 37° C), the operating limitations is
15°F (-9°C) or above 125°F (52°C). If temperatures consistently drop below 32°F (0°C), install
within a heated building. If this not possible, protect the safety/relief and drain valves from
freezing.

the ones I've taken apart have had teflon rings. dn't remember if the pistons were coated, or not.
