O/T Air Compressor Suggestions

I'm in the market to replace a 15 year old 100 HP Leroi air compressor.

I came here asking for any advice on what to look for, or what to stay away from.

I can talk to the Compressor people who service our machines, but I am hoping that I might get some unbiased opinions here.

we have 3 150hp quincy Compressors that have been great and give 0 trouble. adn we asol have some sullair that have been good all water cooled.

I have had the best luck, and lowest maintenance, on Quincy air compressors.

Have been involved with a few Kaiser's and they do last, but I think they are high maintenance.

Just to Follow up...
We ended up getting the Quincy Model: QGS 100
It is so so quiet, especially compared to the old LeRoi that we had before.
Six months running no troubles.

Thank you for follow up, and addition questions

Just curious...

It is important in industrial facilities to have "Clean, Dry, Air".

When you have this new air compressor, is that it? Or do you still need after-Coolers, and down-Stream water-separators, and compressed air DRYING equipment?

Does your new air compressor have on-board KWHR metering? If your air compressor records KWHR, you can back-check that number with what you are paying per each KWHR from your electricity utility supplier to determine you cost per month/Year for compressed air usage.

Thank You,

Last two plants I worked had Ingersol-Rand. Lots of problems that required us to get rentals.

Lots of plants in the area are using Kaeser. Can’t speak personally of them, but “he said” they have no issues.

I would suggest this,
Instead of replacing your 100HP with a new 100HP compressor. I would opt to install three 50HP compressors.

Keep them rotated and you will always be able to service one of the three. If there is a problem with one, you have a backup.

We have a pair of 100 HP Ingersoll Rand IRN100H-CC Nirvana VSD compressors installed about 13-14 years ago. Nothing but trouble, and evidently due to the troubles they had with them, IR no longer makes that type of compressor anymore. Unfortunately, their equivalent replacement is about a foot taller and 2 feet longer, so two will not fit into the space that my predecessors shoehorned these into. I like the idea of 3 50 HP units, but again, no room, unless I abandon the current supplier (they only handle IR). We have heated desiccant dryers, because we need instrument grade air, but those are working fine.

Yes Clean dry air is important.

No we still need water-separators / dryers.

I looked through the menu for KWHR data, but I didn't find anything.
We are still going to turn in what we have to the City, because that is who we purchase our electricity from.

Good advice, but unfortunately I have space constraints much like Mark.
a 50 HP compressor is not physically half the size of a 100 HP one, nor half the cost.

OT (a little)

I know its not a option... but anyone looking for a small home/office/shop, this one is the best by far, I can have it running 5ft from me and answer the phone and still talk to the person on the other end

Agree 100%

I have a small one and it is super quiet.

A little story that might be worthwhile for someone:

We have three 90kw Atlas Copco dry screw compressors. Our normal demand is two. Recently after a rare shutdown weekend, the discharge check valve of one was stuck open. When the first compressor was started and charged the lines, the stuck valve compressor ran reverse at a substantial speed and quickly destroyed both stages. Considering repair cost, we replaced the entire unit.

We have a great idea to add a test dump valve and an external check valve with a small tube bypass, just enough for the pressure sensor to function but not enough flow for destruction. Opening the test valve, we could periodically test the added check valve. Of course we haven’t actually done that yet...
