ORIGINAL OWNER CAMPBELL HAUSFELD TWO STAGE TWO CYLINDER RECEIVER MOUNTED AIR COMPRESSOR.As you can see from the pictures this unit is almost brand new and was the last fully manufactured in the UNITED STATES compressor that CAMPBELL HAUSFELD sold.This is the largest and most commercial unit that you can run on 220 volt non commercial house voltage.This is a 80 gallon tank and puts out 175 pounds of air with 21.56 C.F.M. of air which is phenomenal and all done with a magnetic start 5 horse power electric motor.Please note this is not your china made harbor freight unit that wont last much over a year and even at that this is half their cost.This unit brand new right now is over 3000.00 Dollars so it truly is a deal.I just sold my home do to a job loss and this is the only reason Im selling this unit.

Worth the $$$ - I am looking for a horizontal compressor!!!!!

Well, 21.56 CFM must be at 20 lbs of pressure or something. Most 5 horse compressors put out around 12 CFM @ 90 psi, where most people are working. 7.5 hp is the highest you can run at home on single phase 220 power. That being said, I like the unit. Maybe get him to $600?

It is hard to tell from the pics, but that 5hp motor looks small. A TRUE running 5 hp motor is pretty big, the one in my Eaton weights about 100 pounds. A lot of companies advertise starting HP for their motors. And as the previous poster noted, no way is that 21cfm at 90 psi.

Lastly, that "looks" like a 60 gallon tank. I'd measure to be sure.

A true 5 hp motor on a two stage compressor will deliver about 18 CFM. A true 7.5 hp two stage will deliver about 24 CFM.

It probably is a good deal but it may not be quite as described. The tank size will be on a metal tag welded to the tank. It also is part of the C-H model number. A 6 in the model number indicates a 60 gal tank, and an 8 indicates a 80 gal tank (cannot make out the model number highlighted) The ending H indicates it is a horizontal tank.

My Quincy 325 puts 18.64 CFM at 175 psi. Down at 90 psi, it is over 20 CFM. You might be surprised at those old, slow compressors.....

Most true 5 HP compressors are in the 17 to 20 CFM range for a two stage compressor at 90 psi.

Meh, it's not a steal. If it t'were me, I would pass.

Yes, it's a little shy of twice to cost, but it's also brandy new. Buying a used tool with a lifetime warranty is one thing, buying a used reciprocating compressor is something entirely different. There is no telling how many hours are on that thing. The pump could be due for a rebuild, if the parts are still available (I've had piss pore like with CH parts).

For mainstream recip's, I'm a big fan of the IR T30's. 2 of the 3 compressors at our haunt are T30's. I have the one I linked to (it's an 80gal, however) and just like the older 60gal it's sitting next to. It's quiet, makes a fair amount of air and has had no issues. Should an issue arise, T30 parts are plentiful.

The setup that I have them in is less than ideal, about a 12x20 room with no ventilation. The compressors get abused during our on-season, 3 - 5hp compressors running non-stop for 5 hours straight non-stop, ambient temp in the room after an hour of running is 90F. They get run this way 5 nights a week for nearly 2 months, which IMO is more abusive than running for 2 or 3 hours a day on and off during a normal work week. I'm pretty sure the new one came with a Baldor motor. Other than filling them with Amsoil compressor oil (changed once a year) and installing automatic condensate drains on them, I haven't touched them. I wish I could say that for the POS Emglo sitting next to them.

I don't think that's a bad compressor, but neither is it the be-all end-all of compressors. I think that if it's what you're looking for, and the price is right for you, then it's just right. It looks like it's been well maintained, and kept clean, and probably has not been mis-used. Had that compressor been in my area when I was looking, that would've probably been very high on the list of possibles.

Question, not to sound persnickety or anything, but how does the motor's horsepower (startup or running) give more or less CFM? It's the pump displacement, and the RPM at which it's driven, isn't it?. I could put a 25hp motor on my Quincy 202, and if it's running at the same speed (1725rpm) with the same pulley size, it's going to be putting out the exact same CFM that it would be if a 1hp motor was running it. Granted, the 25hp motor wouldn't be breaking a sweat, while the 1hp motor would probably melt, but you get the point...

Because they don't use the same pumps. The pump that is on a "startup" 5hp compressor sold in a box store is smaller displacement and output then a pump installed on a compressor with a true running 5hp motor.

sarge,

An easy example would be a Quincy 340. Using a 5 HP motor, it will turn around 400 rpm and yield 13 cfm. With a 7.5 HP motor, the rpm will jump up to 650 rpm and the cfm to 21. Stepping up to a 10 HP motor will get you 900 rpm and around 30 cfm.

The larger motor will allow a pulley change and let you drive the pump at a higher rpm with the same motor rpm.

Haha, I just looked at the ad. How do you even contact the guy? No email address or phone number! Elusive...good sales tactic!

He posted it from a CL account, as such you can "send note" (bottom of the ad)

As far as the "startup" hp ratings and such, those are easily identified by "SPL" on the motor nameplate. I don't think the SPL rating was around when that thing was made. It's easy enough to tell what you're really getting though, get it running and clamp the legs, you should be right around 28A.
