Hi could you please help with identifying the attached compressor. I found it at a scrap sales and want to buy it to restore but found no make or model on it.

It's a refrigeration compressor - looks like it's the one from the
walkin cooler on Noah's Ark.

It's a refrigeration compressor - looks like it's the one from the
walkin cooler on Noah's Ark.

If you really want to find out, plug all the open holes for the
refrigerant lines and stick it in a bead-blast cabinet - As the paint
comes off you might just find a stamped part number in the crankcase
or head casting, or a stamped spec plate on the side.

You may be able to use it as an air compressor BUT you need to flush
the oil in the crankcase and replace it with a mineral-oil based lube.

Note that for refrigeration they often have the oil circulating with
the Freon through the whole system - but it's a sealed system so it
works it's ay back.

The incoming refrigerant suction line goes through the crankcase first
- where it drops the oil and any liquid refrigerant before the gaseous
refrigerant goes through the cylinder. And they don't worry too much
about the Oil Control Rings letting some oil slip by and go out with
the refrigerant. It'll be back.

This makes them less than optimal as an air compressor. Any dirt in
the incoming air gets into the crankcase oil on the way through, and
as the rings wear they tend to spit a lot of oil out with the outgoing
compressed air - To the point you have to put an oil trap in the
outgoing line to catch it, and direct it back to the crankcase before
it runs dry.

Go find a purpose-built air compressor head, save the hassle.

This one (if it's the right size, and you can get new seals and a
rebuild kit for it) would be good for rigging a Home AC Off-Grid, to
run from an alternative energy source like a Pelton Water Wheel or a
Bio-Diesel engine running this compressor and a small alternator for
the lights and fan.

This is really old, for a flat belt drive. Possibly 100 years old.

I pulled a two-cylinder version very similar to that out of my uncle's
shop after he died. It had a leather flat-belt drive and he had
converted it to fill the enormous bomb...er, air tank...that hung from
the ceiling of his shop.

I scrapped it, but it was hard to do.

I think you may have been right the first time (bomb) - especially
if it hadn't been drained regularly or Hydrotested or Bore-Scoped in
forever.

"Hanging from the ceiling" and being run by a flat belt and Jackshaft
system makes it likely it hadn't received proper attention in forever.

A lot of the really OLD refrigeration compressors were set up for
thiings like sulfur dioxide, methyl chloride and ammonia. Freon is
relatively new as a refrigerant. The oil may be contaminated with
some undesirable stuff, hazardous waste. Ammonia takes a LOT of
pressure to liquify, so if it was designed for that, delivery pressure
could be significant. Might make a pretty good vac pump, too, with
proper clean out.
