Anything in the manual or manufacturers website about it. I have a tank
mounted compressor I bought from WW Grainger in 1990 that's still going
strong because I've only used the compressor oil sold by them formulated
for air compressor use. I also replaced the little felt air filter with
a manifold and Solberg air filter assembly when I bought the compressor.
It's probably the one thing I did to extend the life of my compressor.
The Grainger site is down for maintenance right now or I would post a link.
I've been a customer of WW for 40 years and the only thing that
disappoints me is their Web presence. As large an outfit the
company is, it seems it could afford the best in Web design.
The compressor I bought from them years ago was made in USA, now they
come from China. :-(
The oil is on the same page. The compressor was a Campbell Hausfeld and
Grainger sold a manifold to bolt over the intake area where the little
oiled felt filter was located. The manifold had a 3/4 NPT port for a
screw in Solberg air filter.
Campbell Hausfeld still sells a cast iron compressor like the one I have
but I don't know the country of origin which could now be China. The oil
Campbell Hausfeld sells is a 30W non-detergent. There is no mention of
additives in their oil.
I hope this information helps you because I learned it of the years
working on pneumatic systems. One of my talents was repairing Stanley
"Star Trek" air doors once the ubiquitous automatic doors in most
grocery stores, retailers and hospitals. I came up with ways to keep
relatively small air compressors running 24/7 in those applications.
Most folks have no idea of the air compressors running all around them
and what they're used for like operating the air conditioning in large
buildings and keeping the presses and equipment running at the dry
cleaners. Everyone should take a tour of the tunnel system under a large
hospital complex to better understand the hidden technology at the other
end of that simple switch. ^_^
