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--

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.

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).

I just purchased this compressor from a local store for my small business. Here are initial impression in the first hour:

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.

I ordered this after checking local competitors for prices on similar units. The price couldn't be beat. I received it in perfect condition the crating was spectacular and was better than expected. I didn't have any troubles hooking it up and running it either. The unit runs flawless! Very pleased with this compressor on initial purchase and use.

Received in just a few days. Set up and operation were simple.
Works great

works great arrived in mint condition best compressor for the price. on a side note, ceva office told me that they would unload the compressor from the truck. lift gate on truck did not work! driver told me lift gate has not functioned for 2 months!! had to go collect a machine with forks from my shop several miles away to unload. beware of ceva personel in office they dont know what there talking about!!!

Compresor is working well, it was easy to set up but the oil site glass is very hard to read. We cannot tell how much oil is in it.

Love the compressor, had a small dent in the air cleaner from shipping. Porter cable sent me a new one right away.
