California Air Tools CAT-4610S Ultra Quiet & Oil-Free 1.0 hp 4.6 gallon Steel Twin Tank Electric Portable Air Compressor, Silver

For comparison, its about as quiet as an old fridge or a window AC unit. You can easily talk over it at a normal volume while its running. Its bigger and heavier for the same tank size than the Porter Cable pancake its replacing but that thing was so loud the tank would literally ring. Its definitely worth the money if you do a lot of work after the kids go to bed!

I was looking for a quiet compressor. I have been using a porter cable pancake unit. When that thing comes on babies cry and ear drums bleed. I was tired of the noise. The entire reason in purchased this unit was it clam to be quiet. I am shocked. Totally shocked. The noise from this is minimal. It is far from ear piercing. I would classify this as quiet. It is not hype and it lives up to its marketing. I also upgraded to the aluminum tanks. I am glad I did. I would imagine the steel tanks would add weight and take my joy of use away. Spend the extra money on aluminum. Overall—I am thrilled with my purchase. Time will tell how it holds up. Very happy.

The quietest compressor I have ever used or heard. It is very quick to fill the tanks. Very happy with my purchase. I would highly recommend this to anyone.

After one month of use I can say that I am very pleased with this compressor especially at the price I got it for here, which was $238 with tax. It is, as advertised, ultra-quiet, even quieter than the little Senco hot dog compressors. It also draws less current when running compared to other compressors of a similar size and is quite a bit lighter than other two tank compressors. We will see how long it holds up but it seems very well built. I do finish work and we are currently finishing the first of three large houses. This compressor is usually driving two or three brad and/or finish guns all day long and seems to easily keep up with the demand, recharging quickly enough to prevent the pressure drop that happens with other compressors when firing a lot of nails rapidly. You dont have to wait for this compressor, which is good since you often cant even hear it. If you are a professional and looking for a new compressor for your finish crew, one that can keep up and that you dont need to hide in a closet because of the noise this is the one you should get.

This is my third CA tools air compressor and it is so quiet I can not understand how I lived with my old noisy compressor for so long. I used to have to wear ear protection using my old compressor and eventually gave it away to my neighbor. Now I know when he fills his tires - the whole neighborhood knows. All three CA tools compressors work great - no problems yet. The low noise is truly worth the upgrade. I wont buy any other brand.

This compressor is awesome, when they said it was quiet I sort of said to myself, yea right, but when I flipped that switch, I was in awe, you can whisper and be heard with this compressor running, it is light weight and I love the very looks of it, definitely will be buying a bigger one when my garage is completed, would give this 10 stars if I could.

Run well for 3 months then the small black tube in the back popped off. On both Units

This is a big improvement over the usual oil-less compressors available locally. The aluminum tanks reduce weight and allow for easy transport. It has become more difficult over the years to find a gas station that has a working air pump. Most provide hot air in the form of various excuses.

I like the weight but it is quiet that is true but not as quiet as the video.

I used to have pancake compressor for snuba off my dock. Hated to use it because of the noise it produced. The only good thing a pancake compressors does is let you know its recharging the tank from the racket it made. This one is dead quiet so doesnt piss off the neighbors. Thats a good thing.
