Going to pull the trigger and buy a Cassese CS200 underpinner from Active Sales next week. Coming from a manual underpinner I know very little about air compressors and what is optimal. The thread that everyone points everyone to about air compressors on this forum has seemed to die or at least I can't access it so I thought I would just start a new thread and ask my questions here. I am a one man operation and plan on joining 4 to 6 frames a day on average. Currently considering a Silentaire Val-Air 50-24-AL or the Val-Air-50-T-Aire they are both 6 gallon compressor's the only difference being one has an electric fan and "pneumatic wheels" whatever that means. Obviously one of my main concerns is about tank size and if 6 gallons enough to run my underpinner and an blow gun. I'm assuming you just buy a line splitter valve to run both. Also. with the risk of sounding stupid I don't want oil vapor blown onto any art, is that a realistic concern? If so what can I do to avoid this?
