Customer Reviews

Design flaw?
You can imagine my excitement to purchase this brand--
I was soon dissappointed.
From day one this compressor had a knocking rod noise-getting worse with pressure increase-
I also noticed quite a bit of oil in my serparator

I reported trouble -and it took 1 month to get a replacement pump.In the meantime, they had my pump on the bench at the shop.

The new pump had the same knocking noise-
I was told by the service man who disassembled my original unit, there was a large space between the rods, on the crankshaft end-they had been sliding back and forth and the pistons were slapping-
after 10 hours of use-there was 1/4" of metal shavings in the oil.
This is actually made by devillbiss--you will not even talk with a Porter Cable rep.
I was also told to repackage the old unit--
Short story-
in the 2 months I have owned mine-I have had 1 month of use--
Beware-I am sure there is a defect in this model----although the factory rep says it look like mine had a problem--several more have to be reported before they will look into it--

Same as a devilbiss model with certified tank
Purchased only 3 weeks ago,works great. WEG 23amp motor and UnoAir full cast iron pump runs at 1200rpm and is a little loud but acceptable. The clear plastic oil sight glass on mine needed tightening but was easily readable. This compressor uses a single belt drive, no mag starter or finned after/inter coolers like more expensive models. There is only one air outlet at the top of the tank.
All this considered and with sale prices around $850 shipped this is a solid value for you gear-heads or the small/medium shop or garage. It appears to be well built to last a many, many years.

Update on compressor as of 9 18 08.
I have had this over 7 months. I did a lot of shop work and even restored and painted a car. Compressor is still working great with only 1 problem being the drive pulley came loose but was caught by the guard. It seems everything you buy these days needs an inspection before and again after some run time. I reassembled with a little lock-tite on the key way set screw and it's been fine. Still think it's a bargin.

Support?
Tank pressure gauge was broken when the unit arrived, and it's missing the globe valve... it's useless. Called the phone number in the manual, it's Devilbiss (not Porter-Cable), and it disconnects you no matter which prompt you choose. Called shipper, and they gave us the number to Amazon. Amazon's rep suggested we go online and find a number to call... Not good! (If PC or Amazon makes good, I'll repost.)
