80 Gallon Snap-On Compressor (SCFM Concerns)

[RaysnCayne]

Hey guys,

I came across an old 80 gallon Snap-On (so the guy says) compressor for $400 yesterday. I know the oldies run real nice and quiet. And it seems like any vertical 80 gal compressor (cheap to nice used) is at least $500 or more these days. So I was pretty tickled at that price. But then the seller tells me while it runs quiet and is a good machine, it doesn't have a lot of scfm to handle big air requirements of DAs and such. Bummer.

Can anyone give me any info/insight into this model just by looking at the pics? The number on the pump is MK9243. I googled it and didn't get anything.

I've already got a decent 1980s IR 20. It's a two-stage (but somewhat loud for my taste) but it's only a 60 gallon. So I really like the idea of 20 more gallons and a quieter machine for my little garage. However, if this old Snap On compressor won't be able to keep up with my DA-ing (which I won't be doing that much), then I feel - considering all the effort involved to swap them out - I should let this one go.

Agree or disagree?

the pump/motor could just need servicing, i would find serial numbers and/or identifying markers and see what it really is first, and find out what it should be pumping out. an older compressor of that size shouldn't have a problem using sanding tools for too long.


call snap-on, and call IR, and any other makers of older compressors, and try to get an id from that number

I would think that would do a grate job. I'm with Kracin on this look into the motor (looks small what HP?) and pump. I think its definitely a keeper.

Looking at the pictures I think the motor and pulley is the wrong one for it.

My gut is that it could certainly keep up with my piddly mostly-light-duty-use homeowner/shade tree mechanic needs. But to go to all that effort to get it and with the pump being, who knows? 30-40+ years old and likely never serviced, is it worth the effort? Do they even make parts for pumps this old? Or would I have to dig up rare (expensive) NOS pieces to rebuild it (if it came to that)?

Rodm1: Do you think the pulley's too big and the motor too small, or...?
