the purifier is VERY hard to find. There is a haskal filter on ebay today. Type in scuba compressors. Youll see it. There are two in the ad. You could get that cheap. I would never go without a air purifier, though people use those clunky military compressors for breathing air.... whew! The last cornelius I had, I got a bauer filter, and used it. The air was great. I mean fresh and good! My purus has a seperator and filter all in one. It makes sweet air. Tasteless just right. with the best of them, though it is 25 years old. If your really looking for a compresor of some capacity, ruggedness, and ability to take out into the wilds, buy a bauer with an engine on it. You wont be sorry. Look for a purus. They are for sale often. you ought to get one for a little over a thousand! Chucko

There is a stewart warner military flamethrower compressor on ebay now. It says it will do 3200psi. That one horse one cyl will sweat even getting up to 2250psi. There are no attatchments, filters, or guages. Look at the price. Thats a good example of why you should stay away from items not made for a specific purpose. You will have a small fortune in it before its ready to fill a tank. They will never do 3200 as the motors are too weak for such loads. I know. I had 3 of them. I warned the buyers NOT to expect to do more than fill a steel 72. One guy from cleveland I sold one to wrote me back and said he loved his though. He just hooked an old hp hose and filler on it, and ran it straight from the seperator! He said it made good air.. More power to him, but I wouldnt reccomend it!

Hi Chuck, I just received a message from the seller of the 32-R-1500 on ebay. She says that the seperator on the compressor is also a filter. She says that the included charcoal goes in the canister. I see in the picture that the canister is held in place with screw clamps. Apparently you put the charcoal in thru the top after you remove the discharge tee. To replace the charcoal you must have to invert the canister and shake it out. Have you seen a moisture seperator/ filter like this before? I have asked her to send me a closeup of the label on the canister. Tim

I went back and checked the picture again on ebay. That machine is exactly like sold in 56. Where does it blow off condensation??? I doubt you would put coal in through the little hole. Thats unlikely. It would have to unscrew and hold a bag or cartdrige of some kind if it were a purifier. Cornelius sold a SEPERATE purifier. That thing looks like a condenser. Maybe its being used incorrectly. How would you get the gooey water soaked charcoal out of it after a few hours use? Get better pictures. Send me your email in a P message and Ill email you original advertizing pictures.

That model, in that configuration, is the 32R1501, rated at .6 cfm and 2500 psi max.
That is NOT a purifier; It is a separator. If it is being used as a purifier, watch out! Like Chuck said, the charcoal would be all wet in no time, and completely useless.
One of these sold last month for $305, without the separator.
One of these sold a year ago for $633, without the belt shroud (no bigee, IMO).
My advice is to look for another compressor, or offer the seller less than her asking price. It does look like a nice unit. I hope the separator isn't all corroded inside from wet charcoal sitting in it though.

I recently bought a Beautiful Military Compressor. It has a Original 2 Cylinder Gas motor made by Wisconsin Co. . It has a " Colt" Water Proof Electrical system. Built like a Dodge M37 Power Wagon . With a couple a Snorkels and a little modification it would probably Run Underwater . The 3 Stage Compressor was made By Stewart Warner - Pretty Good Quality Co. I do agree with Chuck that most of the Small single cylinder motor models of these units are Under Powered . After studying them for a couple a months I see that there is Several different models of them . Some have Smaller single cylinder motors ,Some have Big single cylinder motors like Hondas .Some, like the one I bought have 2 Cylinder motors . It all depends on How much HP the motor has . There are a Lot of differences in some of these units . Some are even mounted to electric motors 115 V- AC , 24 Vt DC Etc Etc. These were the Best our Government could buy with our money. This one I bought isn't that old actually ,made in 1985 Dated on the Mil .Spec. Tag . It's still in Perfect Condition .I really don't think it has ever been started . I hate to think of how much Uncle Sam paid for this Unit. It is Super Good Quality . Being 2 Cylinders it should Pump up a tank pretty Quickly with out working too hard . I haven't fired it up yet but I bet I can get in Purring in a couple a hours . I've never found much that I couldn't get Running . It has a Standard Moisture Trap with the drain in the bottom. I noticed that a lot of these are rated for 3,000+ PSI . I just need to Modify it a bit . Make a Bigger Better Air intake on the Compressor and move it away from the Motor Exhaust and Get a nice Air Dryer - Purifier unit .If anyone has a good Air Purifier canister unit for sale , please let me know . I already have a Filling Whip . I'd also like to get my hands on a nice High Pressure Flame Thrower . I bet they could be made to work Underwater  |

A quick note regarding the revisions and pictures on the current Cornelius auction under discussion:
The seller now shows that the condenser was filled with marbles (was this common practice?), and the top portion has a compartment which the seller says was filled with charcoal. I don't think that was the original intent of the design. The separator appears to be the same model that was originally included with this compressor, but even the Cornelius ads of the day recommended buying a separate charcoal-filled purifier, leading me to believe that the separator was never intended to have charcoal anywhere in it.
The separator looks pretty decent inside, but I would recommend that if someone decides to spend that inordinate sum to get it, that they reconfigure the separator back to it's intended design (whatever that was) and get an in-line purifier. Maybe the unit will work fine like it is; Maybe the charcoal would get wet; Just be aware you may still need a purifier.
AND, be sure to install a back-pressure valve on the separator output. I don't think these old units had any back-pressure valves other than a restricted opening at the filler. I would think that with no proper back-pressure valve and the separator filled with marbles (thereby reducing the internal volume dramatically) that the separator would be pretty innefficient. I know the intent of the marbles is to increase condensation, but dwell time through the separator is also very important. If this seapartor was not designed to have marbles in it, then it shouldn't have marbles in it!

For anyone interested: The ebay auction for the 32-R-1500 ended with no bidders. It appears that the market value is truely less than the $1000 starting price. Without a filter and with a flow of .6 cfm and a max output of 2500 psi it is hard to see that that compressor would command the same price as a good used 3.5 cfm 3000psi modern compressor. Not to mention the issue of parts availability. I hope the seller will relist it with a lower starting price. Tim

Regarding the 32-R-1500 on ebay: the seller has relisted with a starting bid of $500 and no reserve. I started the bidding off to make sure the seller didn't pull the listing for lack of bids. With a little luck I might have the compressor I want. Tim
