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

Customer works from home. Bought this because my old air compressor is so noisy. This was exactly what I wanted. A quality air compressor that is quiet. I was able to talk with my customer standing by it. We couldn’t believe how quiet it is. Great job California Air Tools!

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

Quiet but it does have to run near constant to keep up. On the plus side it fills very quickly.

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.

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.

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

First off, this thing is surprisingly quiet. Everything works great and practically no leakage. After 1 week at full pressure, there was only 1.5lb of pressure loss. There was a small amount of damage which I am not concerned about. You can run this in the house and not disturb anyone. I would recommend an auxiliary air tank though. I used the tank from the dead 20 gallon compressor this unit is replacing. Less than $8 in parts and its a fully functional tank. I spoke with California Air Tools and they told me that this is a 70/30 motor and that I shouldnt run the compressor for more than an hour at a time so the 4 minutes it takes to fill the total 24.6 gallons doesnt worry me. Sure, it takes a little longer to get 20 gallons of air, but my ears arent bleeding while the compressor is running.

The compressor is one the quietest portable compressor I have ever used. On first impression it is a high quality product.

This is quiet enough that you can have a conversation standing next to it. I have used it in a small 1200 square foot house that we are renovating. Houses that don’t have furniture or carpet are always loud, but I can have this on and stand next to it and carry on a conversation.

Hold on now, my experience echoes another reviewer: using to inflate tires sound changed and air pouring off broken stainless connector on plastic hose. I checked the hose and the 2nd fitting broke off the same way: mid-thread. Tried removing, but no luck- I had to retap both sides replacing plastic with 1/4 soft copper. My guess is the fittings machine torqued to be the point of failure - a really terrible quality issue 100% avoidable. I didnt even bother to call the manu. since sending it back didnt make sense. Price now is +100 more than what I paid. Was: ultra quiet and fills very quickly. So much better than a single-piston it replaced. AVOID until manufacturer gets their act together.
