The California Air Tools 4610A Ultra Quiet Air Compressor is designed to be one of the quietest air compressors in the industry having only 60 decibels of sound. This air compressor makes less sound than a normal conversation (65 decibels). The powerful 1 HP motor operates at only 1680 RPM creating less noise and less wear. The oil-free Dual Piston Pump System is engineered for high performance and durability. The oil-free pump allows you to use in different temperatures and uneven terrains. The 4.6 Gal. aluminum rust resistant twin air tank is lightweight (44 lbs.) and easy to transport. The control panel comes complete with two 1/4 in. quick release connectors that will allow you to use up to 2 tools at the same time and 2 pressure gauges that allow you to monitor the pressure in the tank and at the outlet. This air compressor is ideal for anyone working where noise is a major issue.

Rated 4.7 out of 5 by 54 reviewers.
Rated 5.0 out of 5.0 by Nice Tool Not ever had heard about California Air Tools, I read the reviews and took a chance as I needed to replace my pancake compressor that is on it last legs - to say that unit was loud is an understatement.. Delivery and Price were great. During the winter, I use the compressor inside and it is 'ultra quiet' - I would compare the noise level to that of a sump pump motor - you can easily talk at a normal level standing beside it as it is running. The stacked tanks and handle placement make it balanced for carrying - not as awkward as the pancake model. No problem showing this unit off to others who spend more on other brands of similar design. It is just as quiet. The only thing I can not speak to is the durability of this tool but if it lasts, I would have no problem returning to California Air Tools. December 12, 2014
Rated 4.0 out of 5.0 by Quiet compressor Very quiet, light compressor. However it is not a quiet as stated. In the same room it measures as just over 70dB rather than 60dB. Despite that it is still much quieter than the one it replaces. June 21, 2014
Rated 5.0 out of 5.0 by Best air compressor I've ever had. I like airbrushing scale models and sometimes I work past midnight this air compressor is quiet enough that it dosen't wake the wife and that would be bad, and I like the portability as I can take it with me to hobby meets and it wouldn't cause any disturbance to other modelers. thank you for making such a great product and I would advise anyone looking for a quiet air compressor to look into this 4610A air compressor from California Air Tools.

Rated 5.0 out of 5.0 by Don't for get to screw in the air filter. Ran compressor for first time and noticed it was quieter than a pancake compressor but not as quiet as the comparison video. Then I noticed that the air filter wasn't screwed on and the manual doesn't mention anything about this step. Ran compressor again with filter and it's amazing how quiet it is. I would compare it to when my fridge compressor kicks in. Haven't used it much but I would say this is a keeper. Plus it's light and portable. Also, the picture doesn't show it but mine has a ball drain valve instead of a screw type. December 10, 2014
Rated 5.0 out of 5.0 by quick and great customer service It is very, very quite , All my coworkers are very happy. also other clew and home owners are suprised at this good quite california air compressor. Every body are happy. Just a little thing I have a minor problem, and emailed to customer service center of california air tools Inc. then I got phone call from service manager "George Lopez" in 2 minutes,, What a quick response !!! " and my problem is directly solved. ****** very quick and great customer service !!!! Thanks January 26, 2015
Rated 1.0 out of 5.0 by Disappointed I bought this in June 2014. I was SO excited to have a quieter compressor. However, on the fourth use, the pressure regulating valve would not shut off and it began releasing all the air. I called California Tools and they coached me on some ways to correct the issue. Unfortunately, none of the suggestions worked. Because I got this 6 months ago, the company suggested I take it to one service center to see if the issue is still under warranty (40 min. from me )or mail it back to them which would costs me $28. I am wondering if I got a "lemon" since most of the reviews were good. I saw one other person had the same issue I had. I have owned a Porter compressor for 16 years and it still works perfectly. For now, it looks like I will be going back to this. It might be nosier, but it has proven to be a workhorse. February 23, 2015
Rated 5.0 out of 5.0 by not noise neighbors Really quite. ... I fo some work in my garage and the close neighbors dont hear a thing. You can have a conversation with the compressor next to you running. Snd is not need to raise my voice. Am happy with it February 25, 2015
Rated 5.0 out of 5.0 by Nice and quiet...and a very capable tool. I was hoping this compressor would be as quiet as advertised in the video, and at first, I thought I was going to be disappointed. A few seconds after startup, as the tanks started to fill up,a noticeable vibrating sound could be heard. Then I remembered another reviewer recommending that all the bolts be tightened. Sure enough, after snugging down the four bolts that attach the tanks to the frame [you'll need a pair of 10mm wrenches], the unit was purring like a kitten. Other than that, the compressor was ready to use out of the box and works very well. Excellent all around compressor for the home workshop. I don't consider the loose bolts a quality issue per se, but maybe caused by changes in temperature during shipping [a rather cold January here in the Norheast]. January 25, 2015
