California Air Tools 4620AC

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.

5 Stars
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.

4.0 out of 5 stars A contractor's dream (and his contomer's)
Reviewed in the United States on April 9, 2018
I am now a couple weeks into my new compressor and overall I am very pleased. To start with I will say this is not the best compressor for everyone, however, if you are an idividule/contractor that is often in need of a compressor for work indoors that can still put out. This is it. Do not be fooled by the picture though this model is HEAVY and not as mobile as it would appear. That said it is I am sure far more mobile than the other 2HP offerings and can safely sit in the back of my cab if the seat is folded up. This in its self is a huge benifit as it means I can keep my $300 investment out of the rain and out of the pawn shops. If I do find myself on a job where I need more than 4 gallons of tank storage I can use one of the 10 gallon spare tanks inline just fine.

Now for the meat and potatoes of this review. Is it really as queit as the sales pitch claims? No, it is still louder than I expected at 77db at the compressor. To CAT's credit though it is a much lower pitch hum compared to most other units that have a grating whine, and that 77 quickly drops off as you walk away from the unit. At about 5' away I was comfortable having a conversation with my brother while it ran. At about 8' away I had a conversation on the phone with an associate who couldn't believe that my compressor was running. Compare this to my old *insert brand here* 2 gallon .25hp unit(which I thought was quiet to begin with) and it was about half as loud at the same distance. The impressive thing is that it is managing to do this while delivering enough power to run LVLP, HVLP, and nail guns continuously.

The biggest problem I have with this unit and the only reason that it does not get five stars is the build quality. Although the motor and tank seem to be of a good construction the frame and control panel have room for improvement. When I got my unit I was careful in unpacking and inspected the box for damage and found none. However, when I inspected the unit its self I found a few nicks and scrapes in the paint as well as one of the tack welds had snapped free. I also soon discovered that the rubber handle on the top of my unit had been glued on in a hurry and not properly aligned. The last problem resolved its self as the rubber handle came off all together the second time I picked it up. I was able to glue the grip back on, and straight this time, but this is not something that I expect to do with a $300 compressor. The final quality issues is the control panel that holds the manifold and quick connects in place. It has been said on here before and I will say it again. The plate needs to be thicker so that it does not flex when you connect a hose. This again is not a serious issue and I can live with it/fix it, but again, $300 so I shouldn't have to.

All in all it is a great compressor with a good combination of power and noise level while remaining relatively portable and compact. The only real problem that CAT needs to address are the finishing touches. At about three times the cost of your bargain compressors people expect both a good and good looking tool. If that means the cost of the unit needs to be raised a little to cover the Q&A guy's salary then it should be done. In the meantime I HIGHLY recommend this compressor (or its larger tank model) to all my fellow contractors. Let's ditch the bulky wheelbarrow compressors that people can hear for miles and save our hearing!
