Customer Reviews

4-Gal. 2 HP Wheeled Twin-Angled Tank Air Compressor-DISCONTINUED is rated 4.4 out of 5 by 10.
Rated 5 out of 5 by from Compact design; fast recharge In my crowded garage/workshop, this unit fits well with a small footprint and easily accessible outlet and regulator. I particularly like that the handle folds forward over the tanks to move completely out of the way and keep the overall unit short. There is a sturdy locking pin for when you want to use the handle. The frame is such that the unit can be easily lifted from a single point, which has a rubber handle. It is 85 pounds or so, but "easily" means you can lift it staight up and the unit will not swing and stays level. In use, the compressor recharges very quickly, which is great. On the downside, 4 gallons at 120psi go faster than I expected, prompting the compressor to start, with more corresponding noise than I expected. Overall, this seems better designed than the other units I looked at. I also like that the compressor is oil lubricated (change after 50 hours of compressor run time). I expect longer life and better service than my earlier experience with dry lubricated pumps.

Rated 4 out of 5 by from Solid unit indoors/warm conditions... I have had a few different compressors in my time and have yet to find one that works great in all conditions. I had a big "yellow" one for framing that had a name on it that sounded like "erglow" and it was a HUGE piece of junk...fine homebuilding reviews of this unit will mirror my experience with this model. Had a pancake compressor that was red for trim and hardwood, very inexpensive but man that thing could rattle your ears to the point I couldnt use it indoors. I got rid of all of them and hedged my money that this unit would do all that I needed it to do. So far this has been my experience... Indoors for trim/hardwood, basement framing - great! 5 out of 5! The unit has more then enough volume for two finishing guys or a hardwood gun and a finishing guy. The unit is comfortable in the noise category indoors. Where I have had some issues is in the colder months. I did a big deck overhaul in sept/oct where the temp was hovering around +5c. The unit was blowing breakers on start ups if it had been sitting idle for more then 15 min. I replaced the original oil with a lighter oil and it hasnt seemed to fix the problem. I tried it on a frame job here in november with the temp below -10c most days and it was pointless...we ended up using one of the other guys units and not to say it was perfect but it did a lot better then my unit did...perhaps with more hours on it it will seat itself a bit more and be a bit more forgiving in colder times...

Rated 3 out of 5 by from Bosch Wheels Stink! After reading the review of the Bosch CET4-20W, I have to add: I bought a Bosch 4100DG-09 table saw and both wheels go flat regularly. That's a VERY bad thing for worksite use. Here's the real killer: the wheels must be REMOVED to add air because Bosch puts the air valve facing the frame where a chuck can't get to it. (and because the wheel hubs are offset you can not reverse the wheels on the axles). Did I mention that the wheels are WAY too small for hauling things around uneven construction sites? Save money. buy un-wheeled models of Bosch "portables" and add your own, bigger, foam-filled wheels, or look for another manufacturer who cares about the small details.

Rated 5 out of 5 by from Great jobsite compressor We had 4 of these in operation on one day for a job I had last year. All four works flawlessly. They are not break your ear drums kind of loud. They're not quiet, but they won't send you home deaf either. The controls are easy to find and accurate. My only complaint is that the air filled tires popped one more than one of the compressors. Solid tires would be better, but luckily compressed air to refill the tires was easy enough to find.

Rated 3 out of 5 by from CET4-20W 4 Gal. Angled Tank 2 HP Wheeled Twin It appears well made, however I can not understand why they would design it with the valve stems for the tires on the inside of the rims where you cannot get to them if the tires need inflating without taking the tires off. Apparently the design staff never owned one or they would have put the valve stems facing out!

Rated 5 out of 5 by from The 3 Q's.... Quite (when operating), Quick (when filling up) and Quality (all around). I have owned this compressor for about 1yr and have used it almost daily. I did the recommended break in and check and change the oil periodically. This thing runs like a champ. There is a big difference in performance with this compressor compared to the competition, I know this from experience with the other brands. I do agree with the other reviews that this compressor does not like temperatures below 30 degrees when initially starting it. Although I will say that as time goes on and the more it breaks in, it does seem to start a little better when cold. I do have a 12 gauge extension cord that I use specifically for this compressor otherwise it will blow the breaker when cold. On cold days I will sit there and manually warm it up by turning it on and off a few times before the breaker pops to get the oil flowing a little. Never once has this compressor not been able to start for me and I live in New England with long cold winters.
