2013-05-29 Rotary Screw Compressor, a set on Flickr.
So I finally picked this up to play with and get working. It’s been sitting at my pastor’s house unused, unworking for a while now. I’m hoping to use it to sandblast and re-finish the staircase in my house, as well as help with the Jetta conversion. What, you may ask? It’s a rotary screw type air compressor. They’re known for massive quantities of flow (this one will probably do 12-16 SCFM @ 150 PSI) as well as for being very quiet compared to a piston-type compressor.
Problem is, I’ve never worked on refurbishing a rotary screw air compressor before, and there’s no nameplate on this one. I know WHAT it is, but not who made it or how old. If you can help ID it, or know someone that might, PLEASE share this with them!
I was told that it originally had a 5 HP single-phase 230V AC motor on it. The coupler for the motor appears to be a lovejoy connector. I’ve got a 3 or 5 HP in my basement that needs re-wired that’ll work fine for testing it. I just don’t have any diagrams or manufacturer repair manual to go from to start checking connections, wiring, and piping. Hopefully I can get some more (and better) photos in short order, but this is what I could grab this morning.
