California Air Tools CAT-4710SQ 4710Sq Quiet Compressor Gray 4.7 gallons

The noise level really is quite nice. I’m not speaking scientifically, but the noise of the compressor itself pales in comparison to using a small attachment for cleaning out crevices. In other words, blasting dust out of a car seat cushion or door jamb *feels* about 4 times as loud as the noise of the compressor recharging its pressure. I also like being able to adjust the output pressure down to basically 0 psi. On the downside: The recharge span is factory locked to 30psi. This means you can have the compressor kick on at 90psi and stop at 120psi, or kick on at, say, 40psi and stop at 70psi, but you can’t drain the tank all the way down to 10psi and have it charge all the way back to 120psi. I would’ve liked to use something like the latter to slowly bubble some air through a bucket of compost tea without the compressor kicking in every hour. A bit of labeling stickers would be nice too; the manual is fairly complicated.

Noise level is super quiet. Very easy to have a conversation. Perfect for a small shop. Very easy to carry around, but not so small that its always running! Very well built.

When you would like less noise and still complete any job...this is your answer. Hold a conversation, listen to music and finish your work with this super quiet compressor. Best purchase.

Love it love it quiate compact inexpensive. Im an upholsterer custom window treatment creator. My last compressor got on my last nerve. I play music while working at a low to mid. Volume..I do not hear this compressor. Enjoy!

I read the reviews and this is everything I expected and more. It’s really, really quiet which I love. The only draw back is it’s not on wheels and is very heavy to move a round. Other than that it’s a fabulous buy.

The quiet setting is as advertised - purrrrrrrrrrs. This is really great. I have a Portal Cable 1 gal comp and it was so freaking noisey!! It pumped out a meager .2 cfm. This 4.7 gal comp puts out 2 cfm at 90 psi x 10 times more.. For the size, this a good!

I have used air compressors in a commercial capacity for decades, now - all brands, all makes. California air compressor makes the best, by far! And, this one (4710SQ) only pulls 7.7 amps while cycling. I have a larger version and a smaller version, also pictured. I work in a lot of RV parks and I get no complaints, at all. FYI, the smaller version 1P1060S is a must for any one that has an RV, for sure

Definitely a quiet compressor vs similar pancake kinds. I’m amazed. I leave mine on all the time because when it turns on, the noise is more of a slight nuisance than something I can’t even think when louder compressors kick on.

This particular compressor is replacing a Central Pneumocystic* pancake unit that I bought cheap from Chinese Cargo*, which was really only good for inflating bicycle tires sometimes. Not only is the CAT4710SQ nearly silent compared to that thing, it delivers the goods as far as pressure and volume go. I am now happy that I also bought an upgraded air hose (a Giraffe 3/8 hybrid) instead of another craptastic pre-coiled job. It is not lightweight, though. If not purchased through Amazon Prime, the shipping cost would be as much as the compressor itself. I could wish that there was an add-on available for purchase that would allow for a set of wheels to be mounted. Overall, I am very pleased with this unit. Not quite sure what thickness has to do with an air compressor, but I gave it 5 stars for whatever that may be. *not the real name

Its as quiet as they say, and as light as they say and, yes, the welding is as cheap and poorly done as they say. A reasonable choice if you just need an inexpensive compressor in your garage to inflate the occasional bike tire or blow out a gutter, but not meant for much beyond light, occasional use and not likely something youll be passing on to your kids. If you get a decade of use out of this, youll have gotten your moneys worth.
