California Air Tools 20020 2.0 HP Ultra Quiet and Oil-Free Air Compressor with Wheels, 20 Gallon Tank Capacity, 70 dB Noise Level, Electric, Portable

Shipment came as promised, the assembly was straight forward. Start up instructions were clear. Product runs very quietly. I am using it to supply air to my 24x40 woodshop.

This is my second compressor from California air tools and so far it’s seems just as good as the first one. It was shipped quickly and arrived earlier than the estimate and it was very well packed. It has no leaks, holds pressure, and the auto-drain works correctly. These are quiet, well build compressors, in my experience.My first California Air Tools compressor, a smaller model, is about ten years old now and still going strong. I’ve only had one problem with it which occurred when it was over two years past warranty. A brass fitting in the auto-drain assembly cracked causing it to leak constantly. I contacted customer service looking to buy a replacement fitting, since it was out of warranty. They sent me not one but two new fittings, the second one as a spare in case it failed again, free of charge. I didn’t pay anything for the fittings or postage.You can’t beat that for customer service!

It is the quietest compressor I have ever owned and it's oiless. It compared with 2 quick connects, with a regulator already in place and with an auto drain system installed. My last compressor rusted out in 7 years here in FL so the auto drain is a big help. Overall I replaced a large dual cylinder oil filler double pump compressor with this model. Not can't match the CFM/Pressure combo that my old one could but it's good enough for 99% of the work I need. It does keep enought pressure and volume to run multiple tools at once and pressurise probably 200' of air line I have run in my shop.

5 Stars: A Game-Changer for My WorkshopIn my semi-pro workshop, I take great pride in the items I produce, whether they’re for our home, customers, friends, or family. Once I graduated to finishing my work with an LVLP sprayer, it quickly became clear that my existing 2-gallon compressor was no longer up to the task. The California Air Tools 20020 compressor has been a revelation and a worthwhile investment.Spending half a kilo-buck on any tool is no small decision, but I firmly believe in investing in tools that deliver a return on investment (ROI). This compressor has delivered on all fronts:Quality Finish: The improved performance of my LVLP sprayer with this compressor is evident in the flawless finishes I can now achieve.Space Efficiency: Despite its larger 20-gallon capacity, this unit takes up the same footprint as my old 2-gallon compressor. Yes, it’s taller, but in a workshop where space is at a premium, it’s a perfect fit.Quiet Operation: At just 70 dB, it’s remarkably quiet. Noise wasn’t a key driver in my purchase decision, but I was amazed at how quiet it is compared to other compressors I’ve used at a high-end makerspace here in Texas. This unit genuinely feels like a premium product.Assembly was a breeze. The compressor arrived nearly fully assembled, with only the wheels and anti-vibration feet to attach. The instructions were super clear, and I noticed no quality issues whatsoever. It literally rolled into place once I completed the minimal assembly.The oil-free design is another huge win for me. Low maintenance is a key requirement, and this feature fits my needs perfectly. With its powerful 2.0 HP motor, 20-gallon tank, and impressive performance specs (6.40 CFM @ 40 PSI and 5.30 CFM @ 90 PSI), this compressor gives me the capacity and utility to expand my horizons. Whether it’s spraying, nailing, or tackling other shop tasks, I now have the power and reliability to move work forward apace.I couldn’t be happier with this compressor. It combines premium features, space efficiency, and ease of use into one exceptional package. If you’re on the fence about making an investment in a quality compressor, this one is worth every penny.5/29/25 Update:1 Star: Initially Promising, but Ultimately Dangerous and DisappointingInitially, the California Air Tools 20020 compressor seemed like a fantastic upgrade for my semi-pro workshop. It significantly improved the quality of finishes I could achieve with my LVLP sprayer, maintained a compact footprint despite its larger 20-gallon tank, and operated impressively quietly at just 70 dB. Assembly was straightforward, and the oil-free design promised low maintenance, making it seem like an ideal investment.However, after a relatively short period of use, serious problems have emerged. The compressor has started to stutter alarmingly at the end of its repressurization cycle. It sounds dangerous, as though the sensor responsible for shutting off the compressor is malfunctioning or requires adjustment. This issue poses potential safety risks and is unlike anything I've encountered with compressors in my 69 years.Even more frustrating has been the inadequate response from California Air Tools' customer service. After waiting weeks for a response, I was simply told that the behavior I described is "normal for this unit." This explanation is unacceptable and raises significant concerns about the quality and reliability of the product.Given the safety concerns, poor customer service, and lack of a satisfactory resolution, I can no longer recommend this compressor. It is unfortunate, as it initially seemed promising, but the current issues and the company's handling of them have left me deeply disappointed.6/3/25 Update:Following several weeks of intermittent malfunction, a detailed investigation revealed a serious manufacturing defect - a short-stripped and improperly secured wiring connection at the pressure switch. This caused insulation melting and alarming electrical arcing, posing significant fire and shock hazards. Although I managed a temporary repair to safely continue using the compressor, the support experience with California Air Tools has been deeply disappointing, marked by repeated requests for redundant information and inadequate responses to clear safety concerns.I have included photographs showing the melted insulation, evidence of electrical arcing, and the poorly executed wiring connection discovered during my inspection. Given the seriousness of this defect, the unhelpful and repetitive customer service responses, and the overall risk associated with continuing to use this compressor without proper repairs, I can no longer recommend this product without reservation. Buyers should proceed with caution and thoroughly inspect the unit upon receipt.

I am in love with my new air compressor. It is as quiet as they say in the ads. I have no issues with the volume of air it generates. I have held the air nozzle open while blowing dust out of the garage and never ran out of air after 5 minutes of constant use. The tank is 20 gallons and does not take long to fill. I cannot imagine a better air compressor. I am extremely happy.
