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

I like everything about this machine good product for the money you can’t beat it.

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.

I use this air compressor for airbrushing and I love it. It not loud at all. Yes, you can hear it but not so loud that its drowns out everything. It doesnt take long for it to fool back up after it kicks on. I highly recommend if you are using it inside a building. It is only a fraction of the sound compared to a pancake air compressor. It is not light weight. So its good for sitting in one spot and leaving it.

Very quite compressor, removed the tank and utilize the compressor as a pond aerator pump

The price was great and the unit works fine. At this price if it breaks down you can afford to throw it away.

This is a gem of a unit. Its quiet and pressurizes the tank very quickly. The controls are heavy duty and made for a shop or field environment.

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!

Probably my favorite purchase in the past year or so. I watched comparison videos between these and standard compressors and was worried it would still be too loud. These are insanely more quiet than a standard compressor, the comparison videos do not do them any justice. With how quiet this unit is, I have to wonder how much better the ultra quiet models are, as this is just quiet. That said, I went into this knowing a bit more than the product page mentioned. If you look through all the reviews you may find some that question whether or not they got a used one. These are new, but if you look at California Air Tools page that sells them you will see something left out of the product page here. It mentions there may be paint issues and I believe it also mentions slight corrosion on the fittings. Mine arrived with very slight paint discoloration in some areas and the zinc fittings with some corrosion, no corrosion on the brass. While I didnt see any reason for this listed, I have a feeling these have been stored for a period of time in a warehouse that was not climate controlled. I didnt have any issues with leaks like some have mentioned. I did end up taking off the quick release and adding a 90 degree elbow and a ball valve so I could push quick connects down into place instead of pushing them in from the side. Ball valve was added so I could shut off the air before the quick connect so I can leave my hoses/tools hooked up without air leaking out from them just by turning the valve. My rating may have been lower had I not known about the paint/corrosion issues before hand. But I knew and in my humble opinion its well worth the low cost its at.

Ive tried at least a dozen different brands, mostly the high end stuff. They all chattered noisily! I tried this small California air tool brand to test for noise and now intend to go up to a larger hp/vol

I had a pancake model...I think 4 gallon. It would power on and make me jump. While running it would rotate in a cirxle wrapping up the cord. The it finally stopped building pressure and I had to replace it. I turned this one on and thought it was in some typr of pre-operating mode and waited for it to the kick in. It didnt because that is how quiet this actually was. It didnt vibrate in a circle either. Pressure built up nice and really impressed with this. I got this because of the lifespan and quietness while still having power.
