In North America you can often see the Snap On mobile tool supply trucks trundling around on their routes, offering mechanics and shops a wide variety of tools and equipment, including Snap On branded air compressors. Snap On tool and other products are also available in Australia as well.
As well as the trucks full of mechanic’s and shop tools and supplies, Snap On also has a web presence at which you can purchase their goods including their house brand air compressors.
Snap On sells a variety of air compressors. Most are industrial in size, reciprocating style, from 5 HP up to 20 HP with a variety of vertical and horizontal air tanks. They also offer a quite small 1/10 HP diaphragm type air compressor, in an oil-less version, for small air supply requirements.

The Snap On brand of air compressor is also now available from some big box stores throughout North America. Same quality? Different quality? I am not sure. Snap On does not manufacture air compressors and different sources point to different manufacturers of the Snap On air compressors, though the commonality is they are all of oriental origin these days. To me, then, the quality will be suspect though the price will be low.
Then, the price of the Snap On air compressors from Snap On isn’t low, suggesting (I would hope) that the Snap On compressors coming from their own channels to market may be of better quality than those available from other sources. Any information from you folks on that would be helpful for all.

In March 2017 Casey, a visitor from North Carolina, stated that “Snap-on buys IR (Ingersoll/Rand) Compressors and puts their name and price tag on them. Same design, Same parts, Same compressor, Just a different color…”. That may help when you are looking for parts. Thanks for that. Casey.
And then John wrote in… “FYI, To the best of my knowledge (since 1987) Snap On has never used IR units. back then they used four different builders. Ram Air, out of business and mainly used Campbell pumps (USA). Air Source, out of business, mainly used Schulz pumps (Brazil). Dee-Blast, went away from compressors, mainly used Schulz pumps (Brazil). Brama, bought by Sleegers 2009, mainly used Chinook pumps (Italy). The unit S560V most likely has a Schulz 20SD pump. The parts for the pump are still available from Schulz in Acworth, Ga.”

I have an S221p compressor and need piston rings. Can anyone help?
Was given a Snap-on air compressor, dated 04-20-95, ser.9502086852, model919.721981. Does need oil, what type & where can I obtain a manual. Can’t seem to find where to put the oil?
Funny, that looks like a Sears/Craftsman number, but isn’t. Can you double-check it?
How about a few pix of it while your at it?
Looking for the correct pressure switch for the s580V. It’s a air source/snap on model v motor 100 gallon. I bought it burnt up and attempting to fix it n locate the correct pressure switch
A pic or three might help…or maybe the original switch p/n. The motor is connected directly to the switch, or is there a mag. starter?
The main things are the HP of the motor and/or FLA from the motor, and the cut-in and out pressures.
I suspect it will be a two-stage. It may be 150 or 175 cut-out, check the tank label for W.P. or look at the tank PRV (safety valve).
This had a square d pressure switch with a on/off switch.
And?
Pop off pops off about once per second
That’s weird. It should pop off and not close again til the pressure drops substantially. Meaning it couldn’t pop that frequently, unless maybe the tank is full of water – you do drain it, right?
Have you tried cleaning it?
