I just picked up a gas compressor from a service truck pretty cheap. I don't mind just running it as a gas compressor but my neighbors probably won't like it as much as I do. The gas motor is a Briggs and Straton 5 HP motor that runs at about 3300 RPMS. The compressor is a Quicy that looks to be a 2-stage compressor. I don't know the CFM or model numbers. What size electric is a good replacement of the gas motor? I'd assume 5hp.
I've got a Quincy QR-25 powered by a 12hp K-series Kohler. I've been looking to either convert to electric or replace the engine. I'll be calling my compressor guy this week for some ideas, so if you can get any model #'s or P/N's I'd be happy to ask about a replacement electric motor size. Quincys came in a WIDE range of engine/motor sizes so it's impossible to give a straight answer without more specifics. AFAIK, mine would run off a 5hp or 7.5 electric motor. Because Quincy uses unloader valves (The mushroom shaped things sticking out of the cyl. head), they're a bit more forgiving of being underpowered than other compressors.
That is correct, double at least because on a 4-cycle you only get power every other rotation. Most have a bit more to accomdate less then optimum motor conditons. You'd be ok with a 2hp with a 1.15SF.
Very good choice. Says it's reversable so direction of rotation doesn't matter. Kinda expensive tho...if you shop around for a bit you can find a much bigger motor for that same price.
