air compressor

CountryCase · May 6, 2016

I was wondering if anyone on here has a Polar Air Eaton air compressor? I am looking at the 7.5 hp V4 80 gallon. They seem very well built an have the best warranty. I will be using it to sand blast my old tractors an paint. I also have quite a few air tools that I use to do my own mechanic work. This is a BIG investment for me an just want to make sure I get the right one. Thanks for the advice an have a good day!!

Do you have a CFM rating for it , Sandblasters eat up air quick...

CountryCase · May 6, 2016

The specs say 29CFM @100 PSI and 26CFM @175 PSI

If it was me I would price a FS Curtis or Gardner Denver.

One other important thing to consider is the Voltage. What voltage to you have and what motor is on the compressor? If you have good 208 voltage, your 230 volt motor will not be happy

If you are wanting to buy your last compressor try Saylor-Beall.
Their made in St.Johns Michigan,USA.
If taken care of it will outlast you.

Can't speak for the Polar Eaton. I bought an Ingersoll Rand 2475N7.5 7.5 HP 230-1 phase with 80 gallon tank. Rated at 24 cfm @ 175 psi. Really like the automatic electric drain valve. It also has a low level oil shutdown switch. I run a large TP Tools blast cabinet and a host of air tools and I never run out of air.

Lots of good compressors out there, the knowledge to make a good one is not a secret. I've got a Curtis with the 7.5hp motor and 80 gallon tank. It's 22 years old and still chugging. It was $1100 back then WITH the $150 electric starter, that everybody else wanted extra money.

I'd be looking at installed cost from among the ones mentioned in this thread; you won't find a turd with any of them. Including your Eaton.

I have a Curtis 2 cylinder,2 stage that was built in 1938 and it has only had a couple of valve replacements and one
head gasket replaced. It turns at 490 rpms and seems like it is going to last forever. It has had one tank
replacement. When I bought it the riveted tank had a rust hole in the bottom. I put it on a new 80 gallon
horizontal tank and machined v-belt grooves in the flat pulley and it has served me well since the mid 1970's. I
was born in 1939 and it was working before me and probably will be working when I am gone..

I had an Eaton pump about 10 years ago. Worked fine, but I really didn't stress it. They are assembled in Ohio, but the castings are Asian. Eaton probably has some quality control, as people seem to like them. As far as the v4, I would pass on that in favor of a more tried and true inline twin design. Less maintenance too. Most important: ask them about the duty cycle of the pump you're getting and if it's less that 75 percent - move on.

I built my own compressor and used the pump and motor from the one you are looking at. I can run my harbor freight blast cabinet continuously and the compressor runs about 20% duty cycle every 5 minutes. I've run 2 die grinders and never ran out of air.

The paint quality was terrible though. It started rusting right away. Took 3 or 4 coats to seal everything.
