Customer Reviews

Good Worker - one caution
I like this compressor; quiet, fast, efficient, solidly built. Good features: heavy duty wheel kit, dual connections, good gauges & controls. However, be aware that the drain is not set to drain water completely from the tank in either the vertical or horizontal positions. It needs to propped up at about 45 degrees to get all the condensation out. This is a critical design flaw as residual water in the tank is a big cause of tank failure. Buy the compressor but be sure you drain it well and often.

Wheels are a very good thing . . .
After my last cheapo compressor died in a horrible texturing accident (after five years of faithful service, may it rest in peace at the landfill), I felt like it was time for the real deal. Things that drove me to pick this model in particular:

- Wheels, beautiful wheels -- last one was a dual tank 70 pound behemoth. This compressor is heavier, but those wheels make life so much easier. Granted, I could've used a hand-truck before, but having it all integrated as a single unit is a huge bonus. Not looking forward to the first time I get to heave it into the truck, but for now, it gets around the shop just fine. The handle extends easily and quickly for smooth portability.

- 200 PSI, will I ever use it? Well, um, not likely. However, the more important numbers: 5.4 CFM at 90 PSI is pretty great. Opens up alot of options in terms of running a variety of air tools. While I probably won't ever run more than two framing nailers at a time, this compressor should have no trouble with any other air tools I could conceivably use.

- Low noise. At least, lower noise. Air compressors are noisy beasts, no doubt. This one is pretty tolerable in comparison. Fair warning, the 15 minute, no load warmup period is the noisiest this compressor will be. Once the warmup is over and you close the drain to start building air pressure, the RPM cycles down (almost sounds like it's laboring at first, but it chugs away all the way up to an honest 200 PSI). The normal cycle on is at about 160 PSI, and it runs at around 1750 RPM. It's pretty calm sounding, again, as compressors go. No accompanying vibration.

- Price. It's not cheap, but this compressor compares very favorably to others at this price point in terms of features and technical details.

So far I've only used the compressor for finish and brad nailing. The Dewalt has proven way overqualified for that job. No problems at all to this point. If issues develop in the future, I'll edit the review.

Only gripe thus far: One of the wheels was flat when I opened the box. The tubes are replaceable 410/350 x 4 utility tubes. I just did some creative flat repair. Luckily I had a reliable source of air to pump the tire back up! Take note, if you have a tire that goes flat while the unit is stored upright, it will fall over . . . so keep an eye on the tire pressure.

Happy, erm, inflating.

200 psi...I Like it!
The thing I like best about this compressor, is the fact that I will never lose pressure to my nail guns before the motor kicks on again.
With my old compressor I had 125 psi after the motor kicked off, but after a dozen or so shots with my framing nailer, the pressure would drop to around 90 psi, and the motor wouldn't kick on until about 85 psi, so sometimes the nails wouldn't shoot all the way into the wood.
With this compressor, the motor kicks in when the pressure drops to about 160 psi, and since it pressurizes to 200 psi, I get a consistent pressure through my hose, guaranteed. (I run the regulator at 110 psi for framing nailers.)
Also, since the tank pressurizes to 200 psi you get a larger volume of air stored in the tank than other compressors with the same size tank.

I also like the look, the wheels, the relatively quiet operation, 2 air outlets, the extendable handle, and the ball valve drain.
