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

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.

Bought this to power an airbrush and brad nailer. It is very quiet and easy to operate. Im very happy with this purchase.

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.

We are extremely pleased with this purchase. It is so quiet that we can hear each other talk when the compressor is running, unlike our previous one. We highly recommend it.

I was hesitant to purchase this air compressor given the other reviews, but had friends who swore by California Air Tools compressors. They are by far the quietest compressors I have ever used. I decided to purchase this compressor anyways, and it worked very well at first. After 25 days of owning this compressor and only using it a handful of times, the metal pipe that connects the tanks to the inlet and on/of controls completely sheared while installing baseboards with a 16 gauge nail gun. Needless to say I am completely livid and disappointed at the quality of this product. As much as I appreciate the quietness of the compressor, I would never recommend purchasing anything from California Air Tools. Save your money and spend it on a more reliable product.

Shockingly quiet, I can run it with the kids napping 2 rooms away. Plenty of air for my needs (drawbar on a cnc mill, and a coolant system). Very compact as well.

Back hose was loose and leaked air went to tighten the bolt barly touched it and it snapped off due to the fittings being glued in. Went to take the one of the tank to match up the size and that one snapped off to due to being glued in guess there not made to be fixed with out pieces being snapped off

I bought single tank same motor it works better than I would have ever thought so I bought one for my airbrush shop and for around the house you cant beat these the single tank keeps up with my subfloor and hard wood floor nailers no problem and the double tank keeps up with all my spray guns and its so so quiet love them

I’ve owned this 4610 AC California Air Tools compressor for about eight months now. I only used it a handful of times and one of the metal threaded hose connections between the tank and regulator broke preventing the unit from building up air pressure. The threaded part of the adapter was broken inside the regulator and could not be removed. I tried for weeks to get a hold of someone at the company to either service it or send replacement parts but without any luck. I honestly don’t believe there is a customer service department. I would say that if you want a quiet Compressor, this won’t disappoint however if anything goes wrong, you are on your own.

Huge difference in sound level between this one and two older compressors. I have mounted it in the bed of my truck and with the tonneau cover closed you hardly hear it. Reassessment: I really put this to the test topping off about 40 tires/day (over about and hour) for 3 days. Sorry to say it disappointed as the duty cycle was not sufficient to keep up. The compressor shut down near the end of the hour and would not restart until it cooled down. On the last day I had to get the noisy Porter Cable pancake unit out to do the job. I am going to try adding more storage capacity so it will have time to cool down between cycles.
