This review is from: Thomas Compressors T-635HD 6 Amp 3/4-Horsepower 2-Gallon Oil-Free Hot Dog Compressor (Tools & Home Improvement)

I was looking for a portable and not overly loud air compressor, for my low air-volume tools. I had a 4-gallon pancake compressor for several years, but at 70 lbs., it was just too heavy and bulky to lug around. Sold it and purchased the inexpensive Sears Craftsman model 15210, a 2 gallon, oil unit. The Sears unit came with numerous accessories and was only 40 lbs. -- much more portable than the pancake unit. Unfortunately, it was also VERY noisy, so it was returned.

My third attempt at a portable was the winner. The Thomas 3/4 HP model, at 26 pounds, is so lightweight that I can comfortably pick it up with TWO fingers. It's also very small: 16" long, 17.5" high, and 7" deep. Quality is first rate. Although it hardly qualifies as "quiet", it isn't nearly as noisy as other compressors I've heard. I installed a 16" stainless steel braided faucet plumbing hose on the compressor's air-outlet port; routed the hose out the back under the motor support, and screwed on a quick disconnect coupling. First thing that gets plugged into the quick-disconnect is a regulator, since none comes with the unit. This setup works fine. Because the tank is only 2 gallons (to keep weight/bulk down), the pump comes on more often than on larger units, but when it does, it's only on for about 12 seconds (if you're not using air). The unit comes on when pressure drops below 100 PSI and goes off at 125 PSI.

Thomas's Perma-Lube pump design results in a 100% duty cycle. Translation: the compressor can be used continuously, without letup. Some compressors have only a 50% duty cycle, which means you shouldn't run it more than 30 minutes for every hour used, as that could cause excessive wear on the pump and/or motor. The last thing I need to worry about when working on a project is giving my tools a rest.

You'd want a bigger unit if you had two roofing or stud-nailers going, but for low-air-volume requirements such as trim work, this little Thomas unit is just about perfect. If you can afford the best and need a truly portable machine, this is it.

September 2006 update:

While working on a home renovation project, the compressor's low air pressure switch clicked, but the motor didn't start. By the time I got to the compressor, the motor was smoking, literally. Perhaps there was low voltage to that particular outlet in that 46-year-old house. In any case, the little Thomas had sat there for a few minutes just humming; and overheated. Am wondering if the motor would have burned out had I not gotten to it in time. As hot as it was, it should have shut off by itself, but maybe it lacks over-heating circuitry. After it cooled, I plugged it into an outlet on another circuit and it worked fine.

I've had mine for four years now. It's quiet, powerful and never gives me any trouble. I've used it to run nailers in remodeling my house, fill tires on occasion, run my Critter spray gun and blow dust out of corners in my shop. I loaned it to a friend for a month so he could build a back porch. Still looks and runs like new. From what I'm told, it's hard to wear these out, and if you do, Thomas has the parts to do an easy rebuild.

Update: It's been eight years now since I bought it for a home remodeling project. It's still driving nails, spraying paint and varnish, filling tires, and blowing dust, and it still works like it did when it was new.

It is ideal for any small project contactor. You can use a framer with it, its very quiet, its light, it recompresses quickly, and has low electrical draw. I no longer use my emglo (unless I'm on a job more than a week with strictly framing). Spare your back one less heavy thing to pick up all the time and get one of these wonderfully engineered compressors.
