Great Quiet Compressor
By Jacob B.
California
Purchased 10/27/2024 |
Review Posted 11/18/2024
I bought this to run my Plasma CNC. I have a Miller Spectrum 875 and it works without any air issues. I have been struggling to find a compressor that can keep up with this cutter and this one does. It’s quieter than my plasma cutter which is nice :) Definitely would recommend!

Ultra Quiet

Review Posted 01/18/2024
The compressor has worked fine for about 2 months now. It’s very quiet and I use it inside under a staircase and I don’t mind the noise.
It’s started making a chirping noise towards the end of the cycle but I’m hoping it’s nothing to worry about.

Very Good Compressor
By Nicholas P

Purchased 11/28/2023 |
Review Posted 12/21/2023
I was having issues before with my shop compressor that I bought at a local store. It was a 30 gal with a 3hp motor. It could never keep up with tasks such as painting or sandblasting. This is only a 20 gallon tank, but with 4 hp, it can keep a steady 10cfm at 90 psi, which covers most tasks I need to do. And yes, it is moderately more quiet that most regular compressors, which is a nice feature as you don't have to put on ear protection every time the compressor goes off.

Exceeded My Expectations
By Michael D
Pennsylvania
Review Posted 01/21/2023
I have to say that the California Air Model: CAT-20040CAD has exceeded my expectations. I use the Model: CAT-20040CAD to run a large adhesive tape slitting machine that requires large amounts of consistent air flow to operate the machinery properly. I am pleased to report that this unit has delivered. The best part about the Model: CAT-20040CAD is that it is so quiet. This is a great piece that was well worth the investment. The only suggestion I would make is to consider installing lockable castors to make the unit easier to move around.

Quiet Is An Understatement

You can stand beside it and talk in a normal voice and understand everything. It is much quieter than our 3-HP Ingersol-Rand. It has very low vibration too. Very good shipping crate for zero damage.

Quality, Quiet, And Powerful!
By Andrew H.

Purchased 07/07/2020 |
Review Posted 08/07/2020
First off, this thing came in packed very professionally. Bolted down to the pallet, heavy cardboard cover, all parts and manuals neatly bagged and zip tied. When we hooked it up we were blown away by how quiet it is, they are not kidding when they say Ultra Quiet! We bought the model with the auto drain and when it goes off in its increments it's 10 times louder than the compressor. We put a pretty decent draw on the air supply and when the motors kick in it takes 30-45 seconds of on time to get back up to max pressure. We never lose our output pressure. Don't try to save money with a big box store model, buy this and forget it.

Expectations Exceeded!
By John R.

Review Posted 05/07/2020
Normally I would not write a review, but in this case I feel I should. I called the lady at Air Compressors Direct, discussed my need for a very quiet compressor for my home shop that was capable of doing light spray painting jobs among various other things. She was very knowledgeable & polite. She confirmed my choice of the California Air Tools 4hp, 20 gal. Duplex compressor. The order process was fast and smooth. I got a confirmation of ship date & arranged curbside delivery. The delivery driver was courteous and wasted no time in dropping off the perfect, undamaged compressor. Moved unit to my shop. Installed the air filters and plugged it in. Even my wife was very pleased with the smooth, quiet operation. Had the compressor for a few weeks now and tried every scenario for my pressure and cfm needs. All in all, best machine purchase in a long time. Great people to deal with. Compressor packaged well for shipping, delivery flawless. Quiet machine. All expectations met!

Yes, It Is Quiet. Makes The Garage Enjoyable Again!
By James S.
Lansdale, Pennsylvania
Purchased 10/09/2018 |
Review Posted 11/03/2018
Unpacked, positioned, wired, turned on, and wow, yes! It’s a good purchase so far. This is so much less stressful a noise volume to live with, we are able to still hear talking and music over the running compressor. It has an impressively clean layout to the compressors wires and hoses, and the motors seem solid. The time to fill is short, and noticeably quite compared to the previous 33 gallon Craftsman which hurts your brains eventually! The auto drain is nice, but you will need to fasten the drain hose to your floor or wall to stop it from whipping around. The CFM output is higher than I am used to for sure, and the recovery time also shorter as well. From all indications, this is a quality air compressor, that hopefully performs without issues. It’s been running about three weeks very lightly, and it will be pushed harder very soon with my project requirements.

Keeps The Shop Quiet!
By Brian T.
Yakima, Washington
Purchased 12/04/2017 |
Review Posted 12/29/2017
While this compressor seems expensive for a 4HP unit it does have a couple of special features that worked great in my small shop. It has a very low current draw at startup for a 20-gallon unit. Only 14amps compared to nearly 25amp when some 2-stage units kick on. This is great if you have a situation where you are low on available power. Secondly, this is one of the quietest compressors that I've ever been around and it cycles quickly. The auto-drain feature is reliable and is one less shop task that I need to deal with. This unit provides air for two CNC machines with enough left over to operate a blow gun. Small enough to tuck in right behind one of the machines. It even showed up with the plug already wired and was up and running in 20 minutes without the need to build some sound proof box for it. Overall, a good, quiet, low maintenance, suitable for general shop use. Probably not enough CFM for a blast cabinet, but makes enough air for everything else.
