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

Where was this machine all my life? If all I needed was to keep my tires inflated I’d probably still buy this. A pneumatic nail gun prompted me to buy this. I never know if something this inexpensive is just a Chinese knock-off or a safe, well-built machine. Time will tell, but so far I’m living the whisper quiet operation and solid construction. It weighs a bit much, so I’ll likely put it on wheels. UPDATE 2022: I have somehow made excuses to buy pneumatic tools just because of the great compressor. I made it sound near silent in the original review. It’s not. But relative to its peers there is no comparison. I did have a part failure that took some work and really thread compound to replace successfully. Not expensive though. And I’d still buy this again.

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.

OK, I love this damn thing. Well made and really quiet as compared to other compressors. My vacuum cleaner is louder. You can sit next to it without ear protection and your ears wont bleed. For the price I would give it 6 stars. If you wanted an even quieter compressor with the same range of application be prepared to take out a mortgage. Because of this machine I will always look for a good deal on California Air Tools compressors in the future, god forbid something happens to mine. No, I do not work for the company, just appreciate a machine that does what its supposed to do. I use it mainly for airbrushing but it has the power for a much broader application. Very much recommend.

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.

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

Overall the compressor is great. Quiet and well designed. However the one I received had some assembly issues. Three out of the four motor to frame mounting nuts were loose. I wouldnt have noticed them but when I was initially running it for the first time one of the nuts completely fell off. The handle set screws were loose. Also the air filter housing was bent into an oval making it difficult to access the filter. Again good compressor but some quality control issues that need to be addressed.

I love the fact that this compressor is really quiet. I can run it in the house without it making a lot of noise. It works as well as other compressors I have used. The only issue (and it is not a big deal) is the weight of the unit. It is fairly heavy and cant be carried any great distance. Since I transport it via vehicle, I can put up with weight. All in all, a worthwhile purchase.

I have been using the same pancake compressor for about 12 years and the noise has always been unbearable. This new compressor is so quiet I dont even notice it running. I havent used it for anything yet besides a few test drives on my brad nail gun but it seems up to the task. I am absolutely overwhelmed by the quiet. I hope this one last as long as the last one but regardless the silence is worth the price.
