1. Being a carpenter in the north east I require a pretty heavy duty compressor that is low maintenance and can start up all year round. I shopped around before going with the Bosch, and it definitely lives up to expectations. I had already purchased a new Bosch (FNA250) angled finish nailer and was very impressed with their new technology, basically lighter and smaller, with more power. This compressor stood out from the other twin tank models for several reasons but mainly because of it’s mobility and good strong design.

   I like the fold down handle for storage, it fits right under my work bench no problem. And when extended you can wheel it around without bending over, unlike the Dewalt and Makita model. The wheels are pneumatic and high quality, and allow it to go right up stairs. Also it has two intelligently placed handles at the bottom of the two tanks and one on top for one and two man operations. Overall it is relatively light for its size, but I almost have never had to muscle it around because I favor the wheels. My other compressor (Hitachi EC12) hasn’t left the garage since I bought this one.

   This compressor must have been designed by someone who uses one daily. The whole compressor is surrounded by a sturdy roll cage. All the air fittings and gauges are recessed between the tanks which protect them from being damaged. The air release valve is conveniently located between the tanks at the bottom of the unit for effective water and air draining. I did have to change the couplings because the ones that come with it weren’t compatible with all my other hoses, only took 10 mins. Also on my other compressor I had mounted a water filter right after the pressure regulator, but there isn’t any room to do the same on this model. I am going to have to put it “in line” after the couplings somehow.

   Another nice feature is the slow start motor, which draws less amps upon start up, so your not always tripping weak breakers. The power cord is very heavy duty and good quality, looks like it is 10 gauge. Also the recovery time is amazing, this motor is a workhorse, and fills the two tanks to 125 psi very fast for being 2 HP. It is not the quietest compressor, but because it recovers so quickly (appx 10 sec) it doesn’t run that much.

   Overall it is an expensive compressor, but well worth it because they didn’t sacrifice quality in it’s design . You really get what you pay for, so you might as well pay an extra $150 for something that won’t kill your back, and is REALLY WELL MADE. Mine has already paid for itself and some.

2. This is a great compressor. I replaced my six year old ChargeAir Pro with this unit and couldn’t be happier. For its size, this is a splendid compressor. It quickly recycles (10 sec or so). Some consider its weight as a disadvantage, however, the fact that it is a tad heavier, to me is indicative of ruggedness. The fold down handle is convenient large rubber wheel facilitate ease of movement. Initial break-in instructions are clear and the process takes a little over 20 minutes.

3. Like another reviewer, mine came with a broken air filter. The stem of the filter snapped off en route I suppose….still awaiting to hear back from Bosch on my service ticket number for a replacement. Started and stopped without issues, only ran it for about 20-25 minutes as recommended by the manual. Will update later once I put it thought real work and when/if Bosch responds.

4. Arrived on time. Works well. Had broken air filter. missing hinge lock right out of the box.

   I’ll let you know how Bosch responds to my phone call.

5. I bought this to replace my old dewalt air compressor and I could not have gotten a better replacement. After bolting on the wheels and 20 minute break in period your in buisness. This compressor pumps up and recovers very fast. I like the center drain valve as it makes draining the tanks a walk in the park. The pneumatic wheels make moving this compressor around the jobiste a breeze. If your looking for a mobile compressor that recovers fast this the compressor for you!
