Hitachi's 2-horsepower compressor is one of the hardest-working units on the market. Plug it into any standard household outlet and get 4.1 cfm of free air at 90 psi--enough to easily run two tools at once. Because of its compact size and trim weight, it's the perfect compressor for the home do-it-yourselfer, but taking into account its power and portability, contractors will love it, too. Minimum maintenance keeps this baby humming for years--all it wants is lubrication. The 2-horsepower, direct-drive motor runs at 14.5 amps, so you won't find yourself blowing fuses or popping breakers. Hitachi's known for workhorse tools, and this one is a prime example.--Kris Jensen-Van Heste

 Great in warm weather June 7, 2008
This thing is great unless you are trying to start it in cold weather. It pops the breaker over and over until it warms up enough for the motor to keep running. I just use it around the house but if you were on a job site in cold weather it would be a problem.
 Great Tool If Used Properly March 26, 2008
I got hooked on Hitachi tools several years ago and I have several Hitachi electrical and air tools in my toolkit. I bought this EC12 Oiled Air Compressor about 5 years ago and really like it. The reviews warned me to take care of the vulnerable gauge and pressure switch housings, so no probs. I installed a single 3/8" female air coupler onto the compressor and only use one 50' 3/8" hose and fittings to a reserve air tank modified from a portable (125 psi max) tire-filling air tank. My idea was to keep the heavy compressor out of harm's way. The reserve air tank can be repeated every 100' to extend the range of the work from the compressor, if needed. The reserve tank allows the static pressure to regain, and feeds the next line segment.
A 1/4-turn 1/2" pipe ball-valve closes off the male air inlet of the remote tank. This tank can be plumbed with 1/2" pipe (3/4" pipe tee or cross with appropriate 3/4-to-1/2 reducers)and short pipe nipples, etc., for one or more hoses out and will serve multiple nailers on a roof; I reused the gauge and 1/4" tire filler fittings so I can still use it for a portable tire tank. Plumb the tank to the branch of the tee or cross and the 3/8" air inlet and outlet(s) on the straight-thru run. The 3/4" gauge fitting can go directly onto the vertical branch of the cross.
Each nailer can be fed with a lightweight 10'x1/4" whip on the end of a 3/8" hose of any length, but no nailer is starved by being a long way away from the compressor. Line loss is just NOT a problem with the reserve tank and 3/8" hoses: all my major air tools have 3/8" male air fittings. I have had no problem with two framing nailers. Three may work as well, depending on your nailers and the compressor's 4.0 SCFM capacity. Taking the reserve tank up onto a roof is easier than fighting with long-line losses due to friction and long extension cords and the voltage drops incurred. Attaching a couple of short 4x4 "feet" (or plastic pipe with clamping bands) to the metal legs of the tank allows the tank to straddle the roof peak and feed the work.
I experienced an occasional burst of air loss when the compressor shut off which would bleed the tanks. I found the spring-loaded rubber check valve poppet had hardened up and I replaced it using a 19mm hex socket, NOT a 12-point socket which can slip, to remove the cast brass hex nut on the top of the compressor check valve housing. This check valve housing is located on the side of the top tank where the metal line feeds from the compressor cylinders and a new poppet cost me $7 at a local tool repair parts house. Air pollution will harden them, so buy them fresh.
I blew a circuit breaker a couple of times on start-up until I figured out my garage outlet powers my freezer and my home office (all on a 15 AMP circuit breaker: I don't have that problem anymore.) I only use one 50' 12/3 AWG extension cord (20 amp), and only connect to a 20 AMP circuit, either wall outlet or generator with no other tools on the circuit.
The black tube which runs from the cylinder to the power switch is the unloader tube and when the pressure switch shuts down, the unloader valve bleeds off the line pressure so the cylinder starts only against atmospheric pressure. If this tube is mashed, blocked or kinked it will not unload the compressor, the compressor will kick-off the circuit breaker when it starts, and if the check valve is hardened, all the air will bleed out of the tanks when the pressure switch shuts off.
This compressor is very useful and gives me 25 more psi than my fixed compressor which has a max output of 100psi. It is a great tool, and reliable, but it won't save you from yourself. As with any machine, there are mechanical and electrical limitations which cannot be exceeded.
Great product, but careless shipping. January 18, 2008
This is the best small size compressor for any job, it is the best oil compressor even in cold weather, and you will not be disappointed. Just be carful when you receive it, I ordered two and one of them had filter broken, and the other one had switch cover broken, but since I have part available I was able to replace them, it's not Amazon, it's the 70 lbs. of shipping weight where anything can happen.
Good compressor, don't get one in the mail! December 4, 2007
Okay, as you may have noticed in other reviews, it seems that it is not possible to ship an air compressor without damaging it. I would say that is true. I got one of these from Amazon in May and it looked like it had been through a war. The handle was bent, the regulator was snapped off, and little parts were everywhere in the box. To Amazon's credit, a new one was on the way immediately after I reported it. I got the second one and it seemed to be okay. My project got delayed for 3 months, so I didn't use it. Once I started using it, it developed a strange noise 2 weeks into the job. The whole base of the compressor was shattered and falling apart. Whether this was damaged in shipment or if it developed on its own, I will never know. Being over 90 days old, Amazon's policy is to take it up with the manufactureer. I am still waiting to hear from them. When I was using it, It seemed to power up quickly and keep up well. I just wish I had more in service time with it to tell for sure.
 Very loud, and died early December 1, 2007
First, as other reviewers say, this particular compressor is *very* loud. It seems like it could be quieter. Second, I find that in any moderate tool use, it cycles quite frequently...maybe a higher SCFM would be better.
Most importantly, this has to be the least overworked tool in my weekend remodeler's arsenal, yet it's the first one I've ever actually had die. I've owned it for maybe 4 years, but it only gets used a couple times a year. I took care of the oil, always drained the tank, and never kicked it over or dropped it. Yet recently the pressure control switch has failed. Now whenever it charges up, after the switch cuts off at max pressure, some sort of relief kicks in and bleeds off all the pressure it just built up. Useless. I could fix this for about $60 by buying a new one on the Internet, but I'm not happy with the quality so I'm going to switch brands.
Maybe low quality is why this thing is discounted so much.
