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

Wow just wow. If you have ever had a run of the mill air compressor and are tired of the loud and obnoxious sound that it produces then this is the best thing youll ever buy. I have had a 30 gallon oil-less 2.6hp craftsman and it was loud as could be, in the 95 to100db range and if you used it for any extended amount of time it was unbearable in the garage. I got a 5hp 80 gal oiled and it was better but it was still loud and the sound was much lower toned so it was more tolerable. But when i needed a smaller one and stated doing research and California Air Tools kept popping up as the one to go with due to its quietness compared to all the others. I have a friend with a porter cable 6gal for $99 and it seems to be the one that everyone buys, it is loud @85-90db but face it most compressors are and that is what is to be expected. I almost pulled the trigger until i saw this one as an amazon open box for $120 and thought id give it a try. I will tell you that i would happily pay the full price of $200 if i would have been able to hear it run before. It is as quiet as they say. You can have a conversation right next to it while talking at a normal level. The build quality is far above most compressors i the sub $300 category.

Not ultra quiet. I dont have a decibel meter, but I do have ears. I really cant fathom how the CAT compressor would be advertised as ultra quiet. I have a oil lube Jun Air that I would call ultra quiet, the California Air Tools compressor noise level far exceeds that of the Jun Air. The California Air Tools compressor is about as loud as loud talking with of course a more annoying tone. I needed some oil free compressed air, so I guess this will do until I can find a used compressor that really is ultra quiet and fits my budget. If you are short of money and time this is an option if you temper your expectations.

Lighter weight than my rolair compressor. I had it placed by a home air conditioning unit and when i stood between the two the ac unit was louder. Hopefully this will last as long as my rolair as this will be used three days a week all day long.

Wow...this bugger is quiet. Not like refrigerator-running-quiet but compared to my last compressor...Wow!!! I can carry on a conversation standing right next to it. I had an issue after my first time using it...I used the relief valve to release the air in the tank. ( i was checking to make sure it worked). After that I dint use it for a few days and it WOULD not RUN. Couldnt figure out why. Called the CAT hotline and they helped me troubleshoot it. All good and no problems since. ( the pressure switch got stuck in the open postion and the motor stopped) once I got that unstuck...ALL GOOD!

It is still a bit loud, although a vast improvement over my old one. I use it in a dental laboratory and while quieter than my previous unit its still loud enough that in a closet with the door shut across the building from me when it kicks on I cant hear the radio anymore and conversations are difficult to have over the noise. However the dual tank capacity is pretty good and its very compact.

I keep this in my truck for mobile detailing, it has overheated a couple times so you have to turn it off and leave it sit for 30 minutes before turning it back on. I get this is a safety feature but my other 10 gallon California air tools compressor never did this. It could use some more cooling equipment. Other than that it has plenty of power and is very quiet.

First impressions are that it exceeds the advertised specs- and more importantly why I bought it. The unit came securely packaged and double boxed. I mention this as a Hitachi that I had gotten from Amazon a number of years back. Amazon being Amazon handled that situation well, but it was a relief having this one pink and perfect. The Porter Cable 6 gallon that this replaced , served me reasonably well. Though the first one on that and its replacement developed leaks within a month. Should this one do the same, I will update my review. I still have the old Hitachi- and it doesnt leak a bit. To start with, the noise from every other small compressor Ive had is simply rude compared to this little gem. Not only does it run quietly, it performs well. The old PC was starting to draw more amps as it aged. This runs off a nice 5500 watt inverter, but when the 8.5 AMP cold start draw eventually turns into 12 and change, it is time to take the stress off. This one currently pulls 7.4 amps all day long. I opted for the aluminum tank as I am one of THOSE who doesnt drain his tanks as often as I should. I dont spray with it , so Ill be doing well to drain this once a week. You know what the other steel tanks looked like when they were drained. Rust. This is actually close in size to the PC as well. It nestles in the same frame as that one. Bonus. Update June 2022 Shes still running as new after much use.

This is the absolute quietest compressor I have ever owned, great for the house garage.

this is my second C.A.T. Compressor. they are the brand that I prefer due to their dependability and performance to noise ratio. it is worth spending the extra money on a quality tool if you use it day in day out and rely on it to put food on the table. After working with one of these, the louder compressors will just become irritating to you with the noise level they run at. the California air tools can be ran inside your clients house with no complaints of noise, conversating next to the tool while its running is not an issue. recommended for carpenters and professionals as well as DIYers. 5 stars.
