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

Super quiet, but thats why I bought it. Well packaged, it survived intact as I watched the UPS man roll it out the door of the truck (yes, he rolled the square box up the aisle and was end-over-ending it down the stairs when I told him to stop and I would take it from there). At roughly 45lbs, its not heavy, but still not light; however, definitely light enough to carry out of a truck. Would be nice to see an aluminum frame for even more weight savings. The on/off switch is not readable unless you have a clear angle as its black on black. I simply wrote on/off with a white marker to make identification quicker, especially in low light. Because of the small capacity it took some time to fine adjust the regulator to (110psi max) without going below. Once I found it, I marked the spot as a reference. I was easily able to adjust the low limit switch to 95psi (factory appeared to be ~85psi) to ensure my nailer didnt fall below minimum. Finally I dont get interrupted by the compressor, and the baby can still sleep when I work inside. For reference, I replaced a bostich pancake with this unit. I swear the bostich was louder than my 5hp shop compressor. This compressor is being used for nail guns only. You could fill tires and do the occasional blast of air, but capacity is lacking for any flowing air application.

As advertised. This thing is QUIET! I cant hear it very much when Im far away. It does the the job but I do wish it came with universal valves. I had to swap them out for my own. If you need this for light use at home itll do the job but my use was a bit too much. I constantly found myself waiting for more pressure to build up and the motor was a bit too weak. Maybe I shouldve gotten a bigger/more powerful one. Aluminum body does wonders though

Very quiet. No leaks. Love it!

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.

I bought this in December 2019. Just started using it yesterday August 12, 2020. I aired up (4) ATV tires and (2) lawn mower tires. That was all. Possibly 10 minutes run time total. I turned my back and the motor got louder. I turned it off and air was escaping through a broken fitting. (see photo) This new unit didn’t last 11 minutes. I’ve read the reviews and found that this happens often. Cheap fittings! We removed the broken fitting half, and noticed the threads were poorly machined. Extremely rough threads. It’s quiet and light weight but poor QUALITY. I would not recommend this unit unless you’re prepared to throw the dice and see if you win or lose. This company needs to address this issue and then fix the problem. We bought some brake fittings for approx $7.50 for both ends. (figured from the previous review photos that both ends brake ....... see photos) “Hey California Air Tools get on board and manufacture a good product instead of this cheap junk.” You’ve lost a customer here! BUYERS BEWARE!!!!

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!

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

This is a big improvement over the usual oil-less compressors available locally. The aluminum tanks reduce weight and allow for easy transport. It has become more difficult over the years to find a gas station that has a working air pump. Most provide hot air in the form of various excuses.

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

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
