    Compressor Silencers

    Just curious how well these work, anyone used them?

    My Makita compressor came with a filter and cover very similar to that one. It's the quietest piston compressor of that size that I have heard so far.

    Never have myself, step-brother bought a small version for his van mounted compressor, he liked it, but I couldn't tell any difference...The decibel reduction from some of the stats {5 -10} I've read, wouldn't be worth the trouble in my book...just my opi

    Hard to tell from a vid, but here's a little test comparison...might be helpful

    Reducing the volume by 10 dB is perceived by the human ear as cutting the volume in half. If you weren't hearing much difference, I'm guessing the stats came from the marketing department. Sorta like a 2.5 HP router.

    My understanding is that a 3db reduction is perceived as half - so that marketing department may have been workin' overtime to come up with a 10db cut - either way, it'd certainly be noticeable if the claims were even remotely near the truth

    I think you're confusing power with perceived volume. Cutting an amplifier's power in half will lower the volume by 3 dB. Here's a pretty good article explaining it:

    Oh interesting - thanks for that ... somewhere along the line I got 3db in my head. Fixed!

    I had one of those silencers on my last compressor - a 2 hp "Speedaire" from Grainger. The 'silencer' also came from Grainger. It was pretty much the same thing as a paper filter for a gas engine, enclosed in a metal housing. I never thought it did much for lowering the sound. The compressor was still very loud. I did like the idea of the replaceable filter element, though.
