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.

Purchased this compressor in Dec 2018 . The compressor motor burnt up this week. Only used it about 30 hours per year so the estimated use is about 120 hours. The advertisement states the unit life is at least 3,000 hours. The unit was always stored indoors never abused. A replacement motor sells for over $300 including tax and shipping. The unit sold for $330 delivered. Watch this YouTube presentation of how to repair the motor. California Air Tool Compressor Failure and Repair Judge for yourself.

Absolutely perfect! Worth every penny! Flawless! Nearly silent!

Compressor is very quiet and has enough pressure to run 2 trim guns at the same time or a single framer. The compressor I received has a rattle that comes from the brass regulator tube, this would not be noticeable on most compressors because it would be droned out by the motor. I bought this because I have young children and am doing some remodeling around my house and my full size compressor is much to loud to have running in garage. I originally bought this after hearing a friend of mines and couldnt believe how quite it was. Compressor is not silent but is quite enough to have running inside the house with family sleeping (note:work is still getting done compressor is usually one of the loudest things on job site after saws). Silly to say but I think it calms the feeling of a job site because there is no violent screaming of a compressor in the back ground, radios do not have to be as loud and voices do not have to be raised to talk over it. Aluminum Tanks are awesome to avoid rust from forming inside tanks and spraying out when emptying tanks. Also, is light for how sturdy the machine is. I will never cheap out on a compressor again.

This is a great value compressor. Very quiet compared to my old one.

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

I prefer this to my older Porter Cable compressor but I dont like being taken for a ride. This is made in China. It is quieter than my Porter Cable but is far from Ultra Quiet. Durability still unknown. Instructions fair to poor; they tell you for instance to release pressure using the safety release valve but nowhere in the instruction manual does it say where or what the safety release valve is. It is lighter than my older steel compressor, which is a big help. I bought this and a Hitachi brad nailer together. They work well together, but the Hitachi nailer has superb instructions, whereas compressor has poor instructions. It matters.

This is defiantly the quietest and best air compressor I’ve ever purchased. I highly recommend this product a great value & quality for the money.

Pleased so far

This compressor is so quiet it won’t even start. I have repeatedly contacted the manufacturer and they reply with repair videos. I bought this expensive compressor to have compressed air on demand. What I received was a part time job trying to get this thing to operate. The last time I contacted them they failed to respond. I have a cheap (20 year old) compressor that has never failed. It is louder, but I can rely on it to operate. I cannot take my California Air compressor to a job site, because I cannot rely on it to work. Very sad. Very expensive. Look for an alternative before you spend your hard earned money with this company.
