## Overview

The California Air Tools CAT-4620AC is a 2.0 HP ultra-quiet, oil-free air compressor featuring a durable dual piston pump with a 3000+ hour lifespan. Operating at only 70 decibels and 1680 RPM, it delivers 6.4 CFM at 40 PSI from a lightweight 4.6-gallon aluminum twin tank. Designed for professionals who demand quiet, reliable, and portable power with low maintenance and energy-efficient operation.

## Description

The CALIFORNIA AIR TOOLS 4620AC Ultra Quiet & Oil-Free Air Compressor is designed to be one of the quietest 2.0 Hp air compressors in the industry having only 70 decibels of sound. The Powerful "New" 2.0 HP (SP-9421) motor operates at only 1680 RPM creating less noise and less wear. The "New" SP Series of Ultra Quiet Air Compressor Motors have been designed to increase duty cycle and allow for longer continuous run times. The Oil-Free Dual Piston Pump System is engineered for high performance and durability. The CAT-4620AC Air Compressor has a Oil-Free Dual Piston pump designed to have a life cycle before wear of 3000 Plus hours compared to other comparable air compressors with life cycles of 500 hours or less. The Oil-Free pump allows for use in a variety of temperatures (cold starts) and uneven terrains (no oil in the pump). The Easy Start Valve feature allows for a easier start up using less starting amps. The Easy Start Valve releases a small amount of air from the pump at start up to produce a no-load condition allowing the motor to spin freely. This no-load start up requires less amps for an easier start up in cold temperatures. The large 4.6 Gallon Aluminum Air Tank is only 67.2 pounds making it very easy to move around the jobsite. Designed for the person looking for Power, Air Flow, Less Service and Maintenance with at Least 30% Less Noise.Low Amp Draw - 14 Amps

Review: Very quite, quick refill mostly well made - ** UPDATE** Had the compressor a few months now and I love it. Absolutely NO leaks. Leave it plugged in and turned on and never hear it cycle unless I am using it. It's in my shop in the basement so I would hear it if it was cycling. Ready to use when I need it. SUPER HAPPY with it so far. *** I got this compressor to replace a 15 year old, oil bath - single cylinder compressor of the same style. My old compressor got me through a lot of projects and has been a fantastic unit but very loud :-( . This year when I went to power it on for the first time after spending the winter in the garage it will not build pressure. After messing around with it for a while I decided it was time to upgrade to something a but quieter. Of course after ordering the new unit, I was able to find a YouTube video on how to repair my old unit :-) but I decided it was time for a replacement. First impressions: the unit came double boxed with good packing material. There was no shipping damage but it appears that there was "factory" fresh damage in the form of scratches and chips in the paint. Not a huge deal and definately is only cosmetic. Hope to post a couple of videos on how quiet this unit is compared to my old compressor. As other reviewers have said the control panel is a bit on the thin side so as another reviewer suggested, I used a piece of copper strapping to reinforce the manifold mounting points. (have included a lot of pictures). I used a hose clamp to attach the strap to the manifold. When I was shopping for this compressor I was a bit disappointed in the lack of detailed photos so I have done my best to remedy that situation, So far I have tested the unit with my 22g, 18g, 15g and 8G air nailers as well as my 1/2" impact gun and my 3/8" air ratchet. The unit quickly fills the tanks (about 60 sec) and shuts off at 120psi. Cycles back on at 90psi and builds back to 120psi in about 15 seconds. The unit is heavier than I expected but at least 80% of the weight is the motor and pumps. I expect to use this compressor mostly in my shop. If I get to the point where I need to make it more portable I will mount it on a folding luggage cart. The only 2 negative I am aware of at this time are (1) the less than sturdy control panel and (2) the unprotected pressure switch and on/off switch. (see last picture. If U was going to be carrying this in the back of a work truck I think I would weld up a cage to protect the switch from accidental damage. Other than those 2 issues this unit is very well made. If I get the promised 3000 hours of run time out of this unit I will be a happy man. That's basically a year and one half of 8 hours a day 5 days a week nailing.. :-) So far I am very pleased with my purchase.
Review: INCREDIBLE Product! Just DON'T buy it from desertcart. - This air compressor is INCREDIBLE! If you use an air compressor for work or for personal use, this one is GREAT! There are several great aspects to it such as how fast it builds pressure and especially how QUIET it is. I run my compressor indoors and you can barely hear it when you are a room or two away from it. BUT.... Just don't buy it from desertcart. Why? Because you won't be dealing with the normal incompetence we have all come to expect from the delivery drivers that desertcart has. No, you get to deal with a different group of delivery people who appear to have been hired for their complete lack of desire to make any attempt to deliver your product. I'm talking about the freight delivery people. My purchase was made after doing a fair amount of research on compressors. The California Air Tools compressor stood out from the rest. The dual piston design and the high power electric motor really set it apart from the rest. I set the delivery address to my work place address so I could be sure that the "porch pirates" wouldn't get it. And since I set the address to a business address I left special instructions stating that I would be waiting at the address for the delivery, even AFTER normal business hours. desertcart's phone app shows where the driver is and how many stops are before your delivery. The app showed that my delivery was only three stops away. I went to the front window to wait for the driver to arrive. A few minutes later I checked the app and a message appeared stating that the driver reported a delivery attempt was made but could not be completed. This was FALSE information #1 from desertcart. I called the customer service line to ask what happened for the delivery to not be made. The operator said that the driver reported that no one was available to receive the delivery. I asked the operator to look at the order's special instructions. She saw that I had stated in the special instructions that I would personally be waiting at the address for the delivery. Then came FALSE information #2. The operator told me that she would contact the delivery driver and have them turn around and come back. The operator then asked if I would mind giving my cell number to give to the delivery driver so he could contact me when he was coming back. I gave my number and asked how long it would be before I would hear from the driver. FALSE information #3 from the operator was that it would be about 15 minutes when I would hear from the driver. I waited 30 minutes for my California Air Tools compressor delivery driver to contact me. And as you have probably guessed, no contact was made. I called the customer service number again. The operator who answered told me that the special instructions don't actually go to the delivery driver which is something that I can't confirm. But with how desertcart seems to operate, this wouldn't surprise me in the least. Then the operator told me that they have no ability to send any sort of communication to the delivery drivers in the field. Again, this is something that I am not able to confirm. So, if you are in need of a great air compressor that is SUPER quiet and fast I would definitely recommend the California Air Tools line of compressors. The dual piston design will fill the 4.5~ gallon capacity of my compressor in just about a minute. When I do use it I don't have to get out a 100 foot air hose and place the compressor outside, I can have it in the house or the room I am working in without having to deal with the noise other compressors make. The only thing I am not 100% satisfied with about my California Air Tools compressor is the pressure regulator. It isn't the easiest to set to your desired pressure. When you turn the knob it will adjust the pressure in large jumps instead of a few PSI at a time. Maybe this is due to operator error or maybe it is something everyone experiences. Check out their line up if you are in need of an air compressor. Yes, they are more expensive than nearly every other brand out there. But the build quality and the operation of it are well worth the cost. Just don't buy it from desertcart. You'll regret it as much as I do when you get shafted by desertcart like I did.

## Questions & Answers

**Q: How durable is this compressor as a replacement for a Thomas oilless compressor rated for continuous duty ?**
A: I never had a "Thomas Oilless", but my california air tools compressor is constantly running 8 hours a day to run a cnc machine. It's held up very well.

**Q: What size is the drain valve?**
A: Typical tank drain, 1/4" npt I believe

**Q: Whats the amp draw?**
A: It draws 14 amp

**Q: Is this sames as c.a. technologies go portable compressor ?**
A: While I haven't seen CAT's nomenclature, it's a compact work horse. I can recall when 25" TVs were first considered portable but how definitions change. When I bought my CAT material construction, size, intended application (hobbyist, light, infrequent duties around the house), AND generated noise level remained my main prioritized considerations.  I wouldn't call this light and I keep a small moving around but haven't mounted any casters.  Until the day arrives when casters become a daily necessity, I chose to keep the mobility temporary to move my CAT.

### ⭐⭐⭐⭐⭐ Ridiculously quiet!
*by 0***E on January 12, 2026*

My first impression was how quiet it is. I would compare it to being louder than a dryer and much quieter than a cordless vacuum. The tone is low and not ear piercing. I tested my Tornador and it moves enough air consistently to get the job done. It does kick on often but it doesn't matter because the noise pollution is so low. Compared to my 20+ year old 10 gallon compressor I just got rid of, I'm completely blown away.
