Sand Casting Patterns & Supplies
 

Hello, I know I posted to this board already. But realized that it
might be good to post just one more time. I am selling items for a
steel casting foundry, on ebay. If you are a sandcaster, by trade or
as a hobby, I may have some items that you might be interested in. I
have many more than what is currently listed, and will continue to
list over the next several months. Thank you for having such an
active discussion board (one of the most active I've seen!) I've
actually been able to learn some about the items that I'm selling.
Thank you! :)

Hello, all,

I just lugged what appears to be a brand-new air compressor out of the
trash at work. It is a little pancake-style unit, but uses what appears
to be a modified refrigeration compressor. It has a band around it
that holds the top on, an oil fill cap on top and an oil level sight
glass on the side. The rest of the pancake compressor arrangement
is quite conventional.

The maker is Novair, model silaire, rated at 3 M^3/Hr, which works
out to 1.8 CFM. I couldn't find much about this model anywhere
on the web, although the maker seems to be a major manufacturer
of compressors and vacuum pumps.

Anyway, the first order of business is to put oil in it, it appears
to have been drained for shipment. Even if I tilt it, I can't see any
oil in the window. Anyone know what sort of oil would be good for this?
Remember, it is basically a hermetic refrigeration compressor, so the
motor windings are exposed to the oil.

Also, I can't find the air intake on this thing, which is a bit of a
puzzle.

Obviously,it is a 230 V 50 Hz design, hopefully it will run from 240
V 60 Hz without much trouble.

Thanks in advance for any info or pointers on this.

Jon

You need dielecric oil... Go to a place that sells sump pumps... They
use the same oil...
