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--
Service returned a 3rd time to replace the pump.
************* 2-23-2013 edit **************************
After the final repair service call I was informed sandblasting use voided the unit's warranty. They would send a rep to fix unit and then I would be on my own.
I informed them of 2 things.
1-the repair man had already been here and replaced the pump a 3rd time. Unit was running, rod knock sound but running. The sound was worrying me.
And second, that the instruction manual had instructions for proper use while sandblasting. They had nothing to say except my unit was no longer covered under the warranty.
Then , out of the blue, about 2 weeks later a truck dropped off a brand new pump unit and replacement kit, in the box. New air filter housing, pulley, and pump, with 2 quarts oil. :)
I chuckled, stuck the box in my garage for later use expecting this pump to expire at any time. I still have it.
I have had no contact with Porter Cable--Devilbis for over 5 years now.
Here is the good part. While using it to blow off some dust a friend and I noticed the copper coils to the rear were "bent" a tad. this caused them to vibrate on the cast pump housing. Like a rod knock. I stuck a big screwdriver in, made an air gap and whoa! Now this sounds like a compressor.
I have never owned such a large compressor let alone service one, you'd think after 3 visits by an on site rep they would have discovered this. Oh well.
Since this unit has bee running flawlessly for this period of time, and, I have a replacement pump, I must edit my review to a 3 star level. Had the customer service been acceptable I would have given this unit a 5 star rating. Between not catching a simple problem, and Devilbis making me feel bad for purchasing this, I must drop it. I truly hope someone at the corporate level sees this.
Buy Porter-Cable C7550 80-Gallon 30-Amp 6-Horsepower Oiled Vertical Compressor Now
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.

4/04/08 I have been using c7550 compressor for a week now. I have had no problems yet. I bought it to use with my wood sander and nailers,it has no problem keeping up,and when it was delivered it had a big scratch in the tank,but it was not deep enough to hurt anything so I kept it. If I start having problems I will let you know. 4/27/08 still no problems. 8/8/08 still no problems. Today is 01/25/09 compressor still works like new. 4/04/09 The compressor is a year old today and still no problems. 8/01/09 been using the compressor hard for the last 3 months and no problems. The day i recieved the compressor i took the plug out from under the tank and put in a ball valve and extended it out from under the tank so it is easy to drain the water, i drain it every morning. 03/20/10 the compressor is almost 2yrs old now and still not a minutes trouble yet. 11/14/10 still runs and works like it did the day i got it. It is used every day. may 28,2011 still no problems,but have just about wore out one of my sanders. today is 09/06/11 an the compressor still works like it did the day i got it. 5/23/2012 the compressor still works like it did the day i got it. it still handles my nail guns an air sanders with out any problems. i think i am going to wear out before the compressor does.

Despite reading a few negative reviews about this product and immediate problems buyers had at arrival (arriving w/ broken/missing parts; repetitive piston/cylinder knocking even after warrantied service repair of problem) I decided to purchase it. I ordered from Amazon and only two days later I received a call from trucking company that they already had it at local terminal ready to deliver (unbelievable considering i selected free shipping).The unit was packed extremely well and when opened was flawless. Got it it wired up, lines connected and fired it up. Has been running flawlessly for a few weeks now and couldn't be happier with its performance and output. If it continues to perform like it has so far....based on the research I did prior to buying I couldn't find anything remotely close in overall value for what I paid ($793 w/free shipping).
1) Manual says you need to purchase oil. Compressor comes full of oil.
2) Pallet is too short for normal forks at only 1.5". You have to handle the compressor with the very tips of your forklift. I wonder how many get dropped this way?
3) Pressure switch wiring compartment is way too small. For a 23 amp motor we would expect a 30 amp circuit. So 10 gauge wire. The knockout in the pressure switch is 1/2". Even with a knockout punch, there isn't enough room to enlarge this to a 3/4" opening. So rule out being able to properly use 10/3 portable cord. Even once you do find a cord / feed through combination that works, there is little room for wiring. You will need a 10 gauge #10 ring terminal and two 10 gauge #10 fork terminals. The pressure switch terminals don't allow bare wire in; it must be in a fork terminal.
4) Inside the pressure switch one of the hot wires to the motor is white. It should be red. White should only be used for a neutral. I could see this being confusing to some.
5) Air intake muffler is loose and flops around.
Overall I have high hopes for this thing. It seems like a solid product.
