kellogg air compressor

[ponytug]

I agree.

Traditionally, the strategy is to let the compressor store air in a tank at pressure, and then regulate it down to the use pressure. One stored a lot of air at high pressure to deal with surges in demand, and to help remove water.

However, unless you have a tool that needs 150psi (I can't imagine what), or have some use that needs 80 gallons of 150psi air (like putting tires on big earth movers) then running the compressor to 150psi only to regulate down to 100psi is wasting ~50% of the energy. It would be much more energy efficient to have the compressor run from 110-130, and regulate that to the 100psi that you need.

Industrially, one gets a big savings in plant energy use by switching from these old cycling compressors to variable speed compressors that output the required 100psi for process use.

All the best,

Peter

P.S. I would put a good filter on the compressor output and keep an eye on it for awhile. Moving and restarting the compressor might knock free a lot of debris from inside the tank.

Toy, your post got me curious and I started looking online for air regulators. Most I found did not list what I undersood to be a max pressure rating--rather they had a max pressure that they regulate to. Here is a quote from one I found: "Regulates the air pressure from 0 to 160 PSI to give an even air flow". Obviously to regulate to 160 the supply pressure has to be 160 or higher.

I fully agree with ponytug's comments about safety but I wonder if basically all units will handle the 175 psi of the compressor and the difference is the pressure they will regulate to. I have no tools that use even 160 psi--most max out around 100 psi.

It would be just fine if the 0 to 150 max pressure rating was on the out put side of the regulator, but if it was the max input rating at 150 psi then you would have a problem. The reason for my concern is that on the porter cable unit when the contactors stuck and it kept running it was the regulator that blew and started leaking air and not the pop off valve, I just barley touched the outside of the pop off valve and it opened up. The pop off valve should have opened up before any damage to anything else in my system, and I believe it was working properly. I believe it was the regulator that was insufficient, just trying to educate myself on what the psi ratings really mean.

I admit i hadn't thought about the ancillary attachments to an air compressor, but i thought the pop off valves were to help insure the tank wouldn't explode.

I also had an air compressor that welded the contacts and didn't notice until i spelled the compressor and noticed the gauge on the unregulated side was up to 300 PSI and the pop off didn't. admittedly the compressor was over 30 years old and one that i scrounged. I replace the pressure contact switch and put a modern pop off valve on.

That is what I believe it is supposed to do to but the regulator should be able to withstand the additional pressure that it takes for the pop off valve to work before the regulator fails. At $40 bucks a pop you can't afford to pop too many of them. I would be satisfied with the 150 psi output to the tools if I knew that it would withstand the 175 psi going into it. I looked on the Ingersoll Rand web site for information about it but all they have is adds trying to sell their compressors and a bunch of junk that is of no value to what I am searching for. I have searched the web asking every way I can think of about air regulators and basically all I get is compressor sell ads. I have looked kobalt air regulators and basically they don't have anything either. I looked at the instructions that comes with the 150psi regulator and it don't tell what the max input pressure is unless it is the 150 psi.

Kellog air compressors have been around for a long time. CompAir bought out Kellogg in 1971. If the compressor belonged to the father in law it could be an old Kellog. The compressors on these units were built like a tank. They had oil pumps where most manafacturers today rely on the splash method for lubrication.

Compair built quality Kellogg's for about 15 years, and then moved production to Mexico, because they couldn't be competitive in the market using an American made pump. That was a fiasco due to both quality and delivery issues. Compair dropped the line around 1990.

The lubrication system on Kellogg compressors has always been superior to everyone else's splash lube design. Kellogg does not use an oil pump; they never made a pressure lube design. However, they had a patented Ring-flo system that has a ring that positively carries oil from the crankcase, all the way to the top to provide positive oiling where it is needed. They are still made the same way today at our factory in China. These days, pretty much all compressors pumps are built in China, except for IR (India) and a few obscure pumps from Italy. The Kellogg design is still the most robust design on the market today.

Toy, if you got that compressor from the neighbor lady, you should have a good compressor.

I have a Kellogg compressor. Its from the 60's. The tank started to leak this summer. It is one strong compressor. The were built somewhere in Pittsburgh. I am hunting an 80 gallon tank now.

I never got it, instead I got an ingersol rand 80 gal two stage compressor. I ran an airtrac drill that used an ingersol rand compressor and it was a good compressor but that was 40 years ago and a lot has changed in that time but it was a good machine. This new compressor was on sale when I got it and so far it has done good.

That information was interesting - Thanks. I wonder why the others have not switched to that design if it is better than the rest. The patent has to be over by now. Maybe they do not want the expense of redesigning. Gillette had the patents for the basic generator design used by everyone now.

Absolutely. I have a Kellogg American 331TV. Its a "tank" - weights over 200 pounds. It is rated 200psi continuous run or 250psi stop/start. Ive never run it above 170 tho. 170 air from a blow gun hurts, so I ran mine 160/140.

My question is, are parts readily available? It has been idle for a long while after our move and I think its going to need valves and springs.
Thanks,

Parts should be available; search the net. It may use most of the same parts as a 332. However, that model is obsolete. The only models made today are the 321, 332, 335, 352, 452, and the 462.
