After reading many blogs about how to make small compressors in your garage quieter for example. Solberg seemed to be a favorite silencer. Using many different brands, colors and labels, only about 2 companies make compressors in the US and the parts are fairly interchangeable. I just rebuilt my big and small compressors. Small - Sears 33 gallons. and LOUD. When you have a cheap, non-replaceable, plastic air intake filter bracket that costs less than $5-8, you know you're stuck. If you don't want to machine the part, the following is much easier than moving the machine in the annex. It also avoids creating an isolated box which will likely cause your compressor to overheat. Order this 1/4" muffler. It is measured by the size of the pipe thread, which is totally different from the size of the bolts. To avoid cutting a hole in the plastic case covering the pump and motor, buy a 1/4"X2" fitting and a 1/4" coupling. The nipple into the sleeve. Then screw the sleeve onto the muffler. Then CAREFULLY screw the assembly into the existing plastic bracket on the pump (remember to remove the round filters from the plastic bracket first). Hand tighten only to avoid damaging the plastic bracket. Turn the muffler in the plastic five full turns. If You're Done When you're done, you want the inlet on the muffler (the shiny metal sleeve) to be pointing down to keep debris out. This muffler has replaceable filter elements that take less than 30 seconds to swap out. When replacing the filter, do not unscrew it from the pump. Simply remove the cap while holding the assembly with your other hand Muffler - 94dB. (This causes permanent hearing loss in just 1 hour). After installing the silencer-87db. (it takes 4 hours before irreversible damage). Reading with new muffler but 15ft from pump - 81db. (Tolerable all day without permanent damage). By the way without a counter? There are free smartphone apps if you don't have a decibel meter. I used one as I couldn't find my meter. Hope that helps. HM? WHAT DID YOU SAID? :)
