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

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.

Awesome little guy!! Super quiet and a well built unit. The lightest over/under I’ve ever used. The gauges and outlets are well placed. The drain valve is of high quality and easily accessible.

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

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

It’s quiet, lightweight, and meets all of my needs in my home garage / workshop environment where I use it frequently. I have it on a custom-made stand with a 3/8” 100ft retractable air reel mounted underneath it. The hose reel connects into one of the compressor air outputs – and I have a coiled air compressor hose connected into the second output for quickly grabbing and using air around my adjacent work benches. (See Compressor Set-Up pic). I had no hesitation buying this 4610AC as a direct replacement for my original 4610A. It’s marginally more expensive to buy the “A” (Aluminum air tanks) than the “S” (Steel air tanks) but the weight difference makes it more than worthwhile to do so. I will use the frame and air tanks from my original 4610A to add a further 4.6 gallons of air capacity to my set-up as and when needed. I attach a couple of pics showing how this arrangement can work. Those additional bare air tanks can be used in several additive and optional ways in future when a larger reserve air volume is needed. The two bare tanks can even be charged and then easily transported indoors for the odd occasion when I just need a small volume of air to blow something out in the house. Highly recommend this compressor – you shouldn’t be disappointed!

The compressor is ultra quiet like advertised. the cut time cannot be adjusted to anything faster that 90 psi. Great for from carpenters but not for framing carpenters that have to drive 16 gauge nails on to LSL or thick stock in a quick shooting sequence.

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.

I was blown away how quiet this compressor is. The fan in my shop is louder. Absolutely awesome!

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.
