used 5HP air compressor, Grainger Model is 3Z724, needs work. This unit is actually 208, 3 Phase. It's belt driven and only turns 1800 RPM at the motor pulley.
Just my opinions, following. This is tremendous overkill for blowing some dust off some electronics, that being any vintage-computing interest. Especially when considering it will be operated in another room, meaning running air lines to workbenches. Cans of compressed air (or a shop-vac) solve the dust-cleaning problem immediately, cleanly, no oil. Otherwise it seems to me, CDL is talking about labor and capital improvements - like running lines between rooms, housing noisy compressors, equipment maintenance, filters, etc. But CDL didn't ask for advice. They asked VCFed, what as customers of CDL what they might use at their bench. So I'll hold my tongue about advice to CDL. But if they decide against acquiring it: 1) this might be a capital equipment tool, better suited for working on cars, trucks, mowers, big mechanical stuff. Are there not other groups at InfoAge who do that stuff? Equipment Maintenance? or the military vehicle folks? they may find better use, make repairs, make/keep it portable. Then it would be available to CDL intermittently. 2) If the unit is really worn out or busted; there's that 1800RPM 5HP electric motor. That's pretty hefty, and a low rotation rate (most motors are 3600RPM). That sure would nicely feed some rotating equipment (I own a lathe myself). Or maybe a DC or AC generator, as a motor/generator set. and CDL is in the end a "maker" group, parts is part of making (seems to me). But if they don't want a motor like that, some other group at InfoAge might. regards, Herb Johnson -- Herbert R.
