California Air Tools CAT-1610A Ultra Quiet Air Compressor, Isn't Really.

- Comparison of sound output of a 59 dB TC-20 & a 60dB CAT-1610A compressor. The TC-20 is a nice small compressor, but it's really only shown to give a reference point to the sound measurements. The CAT-1610A measured at 70 dB, MUCH louder than advertised.

The TC-20 is still available on Amazon =)
Thank you for purchasing the California Air Tools 1610A Ultra Quiet & Oil-Free Air Compressor.We have every product Independently tested by a certified testing laboratory.The sound level is professionally tested with "Certified" measuring devices in Certified test areas.The test procedure used is authorizes by the EPA - Title 40 Section 204.To clarify the models that were compared were a TC-20 "MINI" Air Compressor 1/5 Hp & CAT-1610A Air Compressor - 1.0 Hp. If you are looking for a quieter air compressor. California Air Tools has 1.0 hp air compressors in Sound Proof Cabinets that are only 40 decibels. www.californiaairtools.com/sound-proof-cabinet-ultra-quiet-air-compressors/
+californiaairtools Perhaps it would be helpful to disclose on the box, 60 dB if you are 20 (MOL) feet away from the compressor. But I appreciate you for responding.
Per Title 40 Section 204 f) Microphone locations.
Five microphone locations must be employed to acquire portable air compressor sound levels to test for
noise standard compliance. A microphone must be located 7 ±.1 meters from the right, left, front, and back sides and top of the test unit. The microphone position to the right, left, front, and back sides of the
test unit must be located 1.5 ±.1 meters above the reflecting plane.
+californiaairtools I'm guessing you didn't test a normal conversation at 21 feet? Maybe the box should say "Makes less noise(when it's 21 feet away from you) than a normal conversation(at normal conversation distance)."
Advertising 60 db at 21feet is misleading. Inaccurate and misleading advertising is a pet peeve for me. Still, for the money this is a nice air compressor. I don't know of any quieter at this hp and price. I'm quite happy with mine. You're not comparing apples to apples. I'd rather have the CAT1610A than the little one you're comparing with. Also notice while it is louder, your voice over the mic is still coming through just fine.
I have the same compressor and it sounds just as loud as the one in your video. Did you find out if there is anything wrong with your compressor or the problem is with the sales team?
+Jung Ko With the sales team. The 60dB sound measurement number they quote was measured while they were 21 feet away from the compressor. If you turn it on and stand one mile away, it is virtually silent.
+Takai2012 I researched this topic a bit more and realized that the compressor comes with a black plastic "straw" that attaches to the air filter. It turns out that this plastic straw reduces the compressor noise considerably!
+Jung Ko Yes, thank you. I was aware of the little black straw. In my video you can see it sticking up from the far corner of the compressor. It does reduce the noise, but not enough.
are you comparing a fish tank pump to a compressor?
+Rocky Ho No, that small tankless compressor is one commonly used for airbrushing. It is here for two reasons. First is so people currently using these can see how much louder this larger one would be. Second reason is to validate the testing, the mfg specs say the little one should read about 58 dB and indeed it does show that on the Sound Pressure Level meter. Which implies that readings taken for the bigger compressor are probably accurate.
That's pretty disappointing. It seems that the only way to upgrade from a rinky dink airbrush compressor without upping the dBs is to employ a refrigerator compressor. Unfortunately, we don't, to my knowledge, have an affordable option like the Bambi in North America. Sourcing and assembling your own compressor with a refrigerator unit is sure to be inconvenient and/or beyond many people's skill set.
+semple3 I know there are fridge like sealed compressors available, but very expensive. There are some based on a slightly better "rinky-dink" compressor, but have a small (1 gal or so) tank attached. That at least removes the issue of the small ones drooping in pressure during an airbrush stroke. I suppose you could also use two of the "rinky-dinks" to feed a stand alone tank. Or buy two small compressors and 1 tank, just switch between them if one starts to get too hot (having a 2nd or spare compressor as a spare is not a bad idea) . Or buy a longer hose for one like the CAT-1610A. If it has to be near you , you could put a box with a fan attached over the compressor to make it quieter and still allow it to cool. Best of luck to you.
Takai2012 Those are all good points. I've got one of the slightly better rinky dink dual piston airbrush compressors. The 3.5L tank on it is great for keeping the pressure consistent, but that's about it. I went with a CAT-5510se thinking that the dB level would be similar to the airbrush compressor, and my experience was the same as yours in the video. I think the pumps are the same or similar. On the bright side, I usually airbrush at 12-20psi, so I can charge up 5.5gal at 120psi, watertrap and down-regulate it and get a lot of spraying time in on a fill. Your video is really helpful for anyone in the same position; they really need to know that there is a significant difference between those little airbrush compressors and what the compressor industry considers a "quiet" (low RPM, intake snorkel) compressor. You can use an airbrush compressor indoors without pissing most people off, but a quiet compressor is still a bit ignorant. Thanks for the video.
You are most welcome, that is exactly why I took the time to make this video.
