I also don't know much about the Varius, they were very small (about 2 CFM most modern portable compressors start around 3.5 CFM) portable compressor sold by Bauer around 1980 and only produced for a few years. I would have a couple of concerns about this compressor, first would be parts availability since it had such a short production run also paint ball people often pump to 4500 psi, high pressure operation tends to shorten compressor life expectency. Filtration from that era is questionable, I have a 1978 Bauer Purus (3.2 CFM) and the filter that came with it is only about half the size of the P21 filter stack that Bauer currently uses on their portables. (note many people complain that the P21 is too small for practical use as filters must be changed every few hours of operation). Due to portability concerns I bought a P21 to add inline with the old filter stack on my Purus purus a while back, the cost was around $400 (filters are about $37 each). There are any number of other 3rd party filters that could be retrofited both cheaper and more expensive than the P21 depending on your need.
