First, the compressor: The unit blasts out an impressive 150 maximum psi for driving more nails than traditional 135 psi compressors. Running on standard household current, this 120-volt electric compressor also cranks out 2.6 standard cubic feet per minute at 90 psi for quick compressor recovery time and faster nailing. Weighing just 34 pounds, the compressor is easy to transport from project to project. And, two quick-connect couplers let the compressor power two nail guns to at the same time. The Porter-Cable Narrow Crown Stapler (NS100) has a built-in depth-of-drive adjustment for precise countersinking of staples. Olson

What’s in the Box
6-gallon, 150 psi compressor with two couplers; 1-1/4-inch, 18-gauge brad nailer; 2-1/2-inch, 16-gauge finish nailer; 25-foot air hose with coupler and plug; 2,000 fasteners, nailer oil, canvas carry bag.

Be advised about this shipping problem with this compressor. Tool Crib should know better than to ship these heavy units in flimsy boxes! Luckily the local Porter-Cable service center is willing to fix it under warranty!.
Good Quality, Great Service - There are a lot of pancake compressors on the market, but this one stands out for two reasons. Second, the Porter Cable service organization. If you're *anywhere* near a medium sized or larger city, spare parts and repair are just a phone call away.

For the remodeler working alone, or the handman looking for a small compressor for the shop, this machine is an excellent chice.
Badly designed pressure switch - The pressure switch occasionally will not shut of the compressor. I called Porter Cable to send me a new one and they wouldn't. I phoned the service center and they said they may not have the parts for this compressor and may have to order them.
Something Different Inside - A slight tug on your air hose is enough to send it rolling. I'll tell you about that one on that review.
Great machine - 8 Oct 02

I read every review I can find on a tool before buying and did so in this case. The problem was, there were a couple `for' and a couple `against' this compressor which didn't help in the decision process (usually there's enough positive or negative comments to aid in making a decision). If you want to ensure you don't have this problem, buy a compressor with a cage around it. Heck what do you want from a COMPRESSOR!

- Plenty of air to shoot my 15ga nails and recovery time on the tank is VERY quick.
A good compressor to get you started. - I shopped extensively for a light duty compressor based on the following criteria: price, weight, and flow rating. It features the same motor and compressor as the PC 3HP twin stack model but is $40 cheaper and about 10 pounds lighter.

Other than that what can I say - it pumps air. It is fairly loud, but I haven't listened to many other models to make an educated comparison. But that's another review. I have used it quite a bit for high air flow operations, such as blowing off dust / debris and even running an air chisel to bust up concrete. It often runs full time for 5-10 minutes and is able to keep up with air demand. If you are going to be regularly moving the compressor around, spend the extra. I actually ran a compressed air line out to my garage, so the compressor can stay put in the basement and avoid potential damage from moving it.

*** 4-year update ***

I have owned this compressor for 4+ years now and am still completely satisfied. I used a hand held, air chisel to break up the mortar joints. The compressor was operating at 100% duty cycle for 10-15 minutes at a stretch, but couldn't quite keep up with continuous use of the air chisel. As an last ditch experiment, I bought a 10 gal portable air storage tank, some extra quick disconnect fittings and rigged up a reserve tank in parallel with the 4 gallon PC tank. (yes, I am an engineer) My thinking was that I would run the crap out of my little PC and if it bit the dust, that was my excuse to buy a new compressor. I am amazed to say the PC compressor ran flawlessly for the entire chimney demo and still works fine today.
