campbell hausfeld 60 gallon air compressor

It's not rocket science and it will work fine either way, sure isolating it is great keeping it on a pallet also is ok. The drain you can busch it down to a 1/4 put 90' elbow with a approx 5" nipple and a gate valve. Or you can also buy a automatic drain that you can work up easily to open for a predetermine amount of time when the compressor turns on. You can either wire it in to the pressure switch, or motor to make that happen. Also I noticed somebody sayed that the compressor was running at 180 p.s.i if that is the case you should not run a single stage pump that high, if that is indeed what you have. I also could have misunderstood. But yes they are like a bomb when they rupture, we actually have a few different ones hanging from the ceiling in our shop with the stories to boot. Lol hope that helped Nic

i did a mistype. i went and looked. its set to 160 PSI from factory. 2 stage unit. My plasma cutter runs it at 120 psi. it still has trouble keeping up at times of high cut output.

That's good if it is a two stage, you can help out your plasma cutter by boosting your top end pressure so it will shut off at 175 p.s.i and turn back on around 145 p.s.i if you told me what kind of pressure switch you had i could tell you how to adjust it, condor? Square d? Furnace? Etc. they all mostly have about a 30 pound differential. Remember this though the higher you go in pressure the more heat you build and the harder a pump will have to work. A analogy I give is if I strapped a hundred pounds on your back you could walk around all day probably with no issues, but if I put 100 pounds on your back you would have to stop and rest periodically through the day. Your pump is capable of 175 p.s.i without any bad repercussion but I wouldn't go above that to much. It would help with your plasma cutter problem a bit. Nic

ill give that a try. Ive adjusted regulators in the past. i havnt messed with this one since it was installed about 5-6 years ago.

Oops I meant strap 10 pounds on your back and it would be easy, strap a hindered on your back and you have to rest. sorry I need to read what I write after.

if i strapped 100 # on my back...youd have to send for some medics.

now if it was a 100# bag of Hershy's kisses or Dove chocolate...then watch out...id be running

Also remember I am not talking about the regulator on the side of the tank Assm, I am talking about the pressure were you turn it off and on. That's we're it would need to be adjust. give it a shot and see how it works.

Lol that's my new example.

Interesting.

I have a table now (As we discussed via PM a while ago) and I run my Hypertherm at 100 psi post air dryer and motorguard. It specifically states in the Hypertherm manual that pressure above 120 can explode the internal pollycarbonate filter bowl.... You are there BTW.

I allow the Hypertherm to adjust it's own air pressure. The new HT units adjust the cut pressure in machine torch mode using the Ohimic sensing cap and the interface.

I run a Quincy pressure lube 2 stage 7.5 horse on a 100 gallon vertical receiver with two 5 horse single stage units as backup and the only time I get into the backup units is if I'm pressure blasting with soda. All three are capable of a tad over 30 CFM running together..... All have K&N filters BTW.

Keep in mind, the lower the receiver pressure, the longer the compressor lasts, the less the compressed air is heated (less condensate) and the less transient moisture is present in the air lines.

I could run well above 175 with schedule 80 steel piping but why bother. It's the useable CFM that does the work.

Besides, the air conditioning has the get rid of the residual heat the compressors make in the shop.

I am a little confused on your question??? Or answer???? The 175 p.s.i is what the compressor shuts off at, not the amount of pressure that would be getting to the plasma cutter. That is what your regulator is for but I'm sure you understand that already. Also in your cutter it has a feature that will make it shut off if it gets to much pressure. Also your are correct in one respect that it is all about the cfm, and not tank size I have to go over that on a daily bases so you are preaching to the choir. on the other hand this particular gentleman does not have a compressor that puts out 30cfm a more realistic number for him is probably in the neighborhood of 12 to 18 depending on what formula you use. So in order to make the most of the compressor that he has it is beneficial to run it at a little higher p.s.i to try and make it perform a smite better. So there the info do with it what you may.
