Question: OK, what am I missing? Does this compressor use 1/4 or 3/8 inch - fittings and accessories?
Document: I got this to replace a 8 year old twin tank compressor that the pressure switch broke on. I thought instead of replacing the pressure switch on an old compressor I would get this and feed it into the 2 gallon twin tank and have a lighter compressor with added reserve when It was connected in the shop.I feed an air line out to my pond so this would kick on 4-5 times a day for 1-2 min.
This Porter-Cable is a featherweight in comparison and it is also surprisingly quiet.Now that I own this compressor, I don't dread having to repair trim-work or fill up our tires. This compressor works well with my 15 gauge finish nailer, but due to the small 1 gallon tank, it needs to cycle after only four (4) 15-gauge nails and about ten (10) 18-gauge brads at 100 psi.
Update: 2/5/13  Air regulator leak solved for my compressor!I don't know if it is in the user's manual, or not, but I have to fill up the primary tank to 80+ lbs. before trying to set the regulator. Failure to do so prevents the regulator from sealing properly and it will leak. Try these 4 easy steps (assuming the compressor has already been properly broken-in):1. Turn regulator all the way to the left.2.
Turn regulator quickly to the right until it seals and regulated air stabilizes.4. Adjust regulator to desired psi.I won't guarantee it will solve everyone else's issues, but it solved my problem - still worth 5 stars IMO.I already own and love myMakita MAC700 Big Bore 2.0 HP Air Compressor, but I wanted a smaller, lighter, and quieter compressor that is easier to use with my finish nailers.
A knob allows you to set the output pressure level to match the pressure need of your device, although with a 1 gallon tank it can't be anything that requires a lot of air flow other than in bursts. A quick connect is pre-installed for common 1/4" NPT coupler plugs.
I purchased this a year ago, have had no issues with it. It's been put to good use around the house, inflating tires, balls, etc. Can actually hold enough air to blow off a very small workplace, but not a good choice for cleaning an entire workshop. I don't hook up any pneumatic tools to it -so I can't speak to that. Cannot emphasize how quiet this thing is. Great addition to my 3.5 car garage work space.
I chose this model due to price, size and quiet-ness. I loved the first impression of the unit. I then put it in storage for a year. When I pulled it out today to use it, I noticed that the Air Regulator flow valve had a huge leak, so much so that the tank couldn't fill up and I could not pump my stuff. I immediately started reviewing the Amazon comments and most of the 1 star comments were due to the faulty design of the valve.
Easy to carry, relatively quiet. I had a 3 gallon Craftsmen compressor that was a pain to carry around. It was also pretty loud. I wanted something lighter and quieter and this seems to fit the bill. Works great with a smaller nail guns like a brad or finish nailer but can't keep up with a framing nailer, three or four nails and you have to wait for it to catch up.
I just bought this compressor and sold my 6 gallon compressor. This unit is fairly quiet (acceptable), I have owned small compressors for 3 years now and mainly do trim work, and drywall texturing with these units. I bought this unit for installing a hard wood floor using a Bostitch pnuematic floor stapler and corner round around base. This worked great, it recharged up fairly quick and feels like it is built to last.
I considered those CO2 tanks with the regulator but that seemed a pain with the bottles and the cost was about the same as this little compressor.Only question I have is who makes the darn thing? DeWalt's version looks identical but painted yellow. Same or similar specs. DeWalt's has EMGLO printed boldly on the front. Emglo is owned by Stanley Black & Decker.EDIT: 2/4/2012Well, I've used it and I like it. Very portable and easily runs trim guns.
Answer: yes
