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.

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!

The air compressor is great, as it is very quiet but delivers much better air flow than competitors low noise units.

Well, they were right...it IS QUIET! It replaces a similar sized one, but it is about half the volume. Fills as quickly as the noisy one. So far, it is great!

Arrived in working condition. Attach the rubber feet booties, the air filter tube, and you’re set. I’ve only been doing light work / nail gun, but just happy to report it works as intended. Also- the tank fills pretty fast, less than a minute.

Compact and quiet for indoor production use. Have it located under a workbench out of the way. Performs exactly as advertised. Very pleased.

Very quiet! Works well, easy to assemble, fast shipping! Had a harbor freight 21 gal compressor that was so loud it couldn’t be used inside. Plugged this in in my kitchen to test it out... almost as quiet as my 56dB washer... very happy with it!

Its really as quiet as everyone says it is if you insert the little tube into the air filter, thats the magic. It really does fill as fast as they say it fills. Ive used mine a handful of times now to inflate tires, dust a few PCs, and even do some cleaning around the house (that pesky spot between the carpet and wall, 100PSI really gets the dirt out!). My vacuum cleaner is louder. Its as quiet as my microwave. Everyone is right, these are great. I get suspicious when I see a lot of 5 star reviews all saying the same things. Nah, this is justified.

This thing is damn quiet! Ive never had a compressor that you could have a conversation while standing next to it, much less one that actually flows a decent amount of air. It has replaced my 6 gallon pancake compressor completely.

This particular item is so so cool it is everything the company says it is I would recommend this air compressor to anyone
