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

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.

I have purchased a lot of small compact compressors. This is the best one I have ever purchased. Moderate white extremely quiet

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

It is so good that I bought one for my son, for the company where I works and one for me, forget about nosy compressor

Love this air compressor! It is whisper quiet and charges fast! Its not heavy to me however look at the specs before you buy. This is a big upgrade over the pancake air compressor I had before. I expect to have it for years to come.

First off I’d like to start off by saying, I was really excited for this compressor from California air tools. I can’t speak for their other models, but this is for model CAT-4710SQ. Arrived falling out of the box. Regulator does not work Psi gauge stuck at 20psi having never even been turned on. Solenoid valve broken Take it all off to find the tank and fitting are rusted inside. I bought this for airbrushing and now that I’ve gotten it up and running, it’s really nice. The box it was shipped In was too big and I suspect I got a returned unit. But all in all it runs quiet as advertised. I’ve been airbrushing till 1am and it’s great! If you were to buy an equivalent spec compressor made for “airbrushing” you’d have to spend way more than this. I had to: replace all the fittings to brass - the ones that were on it were steel and already rusted inside Change the solenoid or “electromagnetism” as it’s called in the manual- mine arrived busted-the one on it is fragile so don’t strip Take all fittings apart and put Teflon tape-When it arrived it leaked a lot Replace the regulator-mine arrived broke and a quick trip to the harbor took care of it for under $20 I can’t say yours will need all of this stuff too. But you will have to take this think apart to get rid of leaks. It’s not too hard, but if you’re not comfortable working on stuff I’d go with a different model. I updated this from 1 star to 3 after the frustration of dealing with all of this. It works, But it does get hot asf

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.

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!

This compressor is as quiet as they say it is. Works great. Easy to use.

This air compressor certainly is quiet! Dont hardly know its on when it cycles. Keeps the pressure up to correct levels for airbrushing or nail gun (intermittent things) but didnt keep up with an air powered sander. Overall it is very useful.
