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

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

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.

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

Quiet as compressor go; leak-free. Good warranty. Top shroud to air filter interference - had to enlarge the slot slightly.

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.

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.

Not as portable as those pancake compressors but a powerhouse of continuous air flow and a completely different class when it comes to the noise. I have not tried bringing it up from the basement workshop yet for other projects but I have used it extensively in my workshop and you do not feel like you probably should get the ear protection on like with my old pancake style compressor. Bigger tank, double pistons, larger motor, less on/off cycling, less noise, cool running. Overall a great purchase for me. The only negatives, size and weight are proportional to the power but manageable. It it portable but I may never move it, maybe I will look onto getting a portable tank for filling the cars tires.

very quit and efficient. I use it as home owner. very good and i have tested air tool from harbor freight like Grinder, sender etc. works great for momentary use. you can use it as blow gun to clean out dust. overall very good product for around the house. Thanks. Samir

You can probably find cheaper compressors but this unit is so quiet and the recovery time is great. It is not too light but you don’t want to compromise just to save a few pounds. This is the second compressor I’ve purchased from California Compressor.

I have owned/used air compressors for about 25 years now. This air compressor by far is the quietest air compressor I have ever used! I truly cant believe the absence of noise. I did replace the coupler right away because it had a very slow leak. To be honest the couple was most likely fine and the problem probably could have been solved with a little Teflon tape, but it needed replaced because my tools use a different style coupler. Overall, this is an excellent product and I would purchase another and recommend to everyone who likes to hear themselves think.
