  • Super quiet compressor for a personal workshop
Style: Manual Drain Valve
The noise level is something else. This replaced a large standard style compressor that I wore hearing protection for when working in the shop if it was running. Now you can have a normal conversation. Tank is small but the system is basically designed to run on demand, I've never run out of air operating my vapor blaster or anything else. BUT it's like the outsourced the painting of the tank to children. I've only had this for a year, it lives in a heated & cooled garage and the paint is just flaking off every weld on the tank and getting rust. I'm going to have to remove the motors, strip it and repaint it to avoid it turning into a pile of rust. ... show more

  • Awful Product and Customer Service Experience
Style: Manual Drain Valve
This order was mishandled from the start. I ordered this compressor to have a low power/low noise air supply for LVLP finishing. The compressor arrived and would not start. After providing the serial number and QR code associated with my particular machine, the customer service representative repeatedly assured me that the compressor had been checked and was running at the warehouse. Upon closer inspection, I found a set of wires hanging out near where the start capacitors should be. They never installed the start capacitors! Not sure how they had the machine running at the warehouse without the pats required to start the compressor. The customer service rep said he had to send an entire new unit (from California, I'm East Coast). I lost a ton of money on two jobs and put out sub-par finishes that will ultimately reflect poorly on my brand. Returning the other compressor was a nightmare. It sat on a pallet taking up space in my shop for nearly 6 weeks because California Air Tools couldn't coordinate with the freight company for a pick up. I was told that it was being picked up on a Friday from 11-3. I received a phone call from the freight company during that window to schedule a pick up. As it turns out, CAT emailed the freight company 30 minutes before to schedule the pick up. Not how that works. Within a week the welds on the exterior of the machine had started to rust. The machine, after light use, has started to get noticeably louder. So very disappointing! I was told I would receive a free air hose to compensate me for the inconveniences. I never received it and when I asked when the air hose would arrive they acted like they had never offered. In Summary - Compressor arrived missing parts - Customer service lied about working status of machine - Customer service was unable to efficiently handle return/replacement logistics - Compressor started to develop rust within a week - Customer service did not make good on compensation offer This company has a lot to figure out. I cannot endorse this product nor the way in which the customer experience was handled. ... show more

  • Compressor Goes Down Hill!
Style: Manual Drain Valve
The compressor was great the first 4 months or so and just went downhill from there. I have had this compressor for just over a year and has gotten noisier as time passes. The compressor has had light use with no were close to the advertised 3000hr mark. My guess is it may have run for 300 - 500hrs with a duty cycle of 50/50 when used with the longest period of time being 6 hours. One of the motors seems to be making more noise than the other. I have reached out to California Air via email multiple times to get a rebuilt cut but no luck. The footprint of the compressor is nice and the once low noise was too. The fact that you can get it is 220v was nice but the main reason for purchasing this was to reduce noise in the garage and higher CFM. There aren't many options for quiet and higher CFM compressors. The hunt continues for a better option. ... show more

  • Good product
Style: Manual Drain Valve
Great air compressor but piss poor shipping by Amazon. Product arrived on time but badly (yet fixable on my own) damaged. Something fell on one of the pumps collapsing the pumps angle iron mounting brackets and cutting the power cord of that pump. I couldn’t return it because I needed it to finish an arch for my wedding later that week ... show more

  • Nice unit but auto water release is well over 75 DB
Style: Automatic Drain Valve
Nice unit but much louder than the 2 HP CA units I have but 75 DB is not that bad. Got the auto water drain, great to have but it’s much louder than 75 DB and goes off as factory set every 2 minutes.

  • Super freaking quite.
Style: Manual Drain Valve
Great compressor. Super quite. No one in the house hears it when I’m in the garage. Only negative about this for me is doesn’t come with wheels. Feels up air super fast and a lot of cfm

  • Both failed in first month
Style: Automatic Drain Valve
Bought two of this compressors with auto-drain function, all failed in first month. The first one's auto drain valve failed to work after couple days of use, it turned out the inner spring of the auto-drain valve was rusty, we had to clean it to make it work again. The 2nd one failed to work properly due to one of the compressor motors was dead! Called tech support who was no help at all even hang up my phone, called back and left my number on voice mail but never got any response! Had to call Amazon to clean up the mess. We have over 10 all types of California Air compressors in our workshop, I don't think it will be a good idea to buy their products again! ... show more
