A few months ago I finally upgraded to a 3HP 60 gal IR compressor. I put it in the shop temporilary (I'm going to install it outside in the spring). One thing I noticed was how small the air filter was and the deep throated noise it mades was at a frequency that was not very pleasant.
So the other day, while at Lowes I picked up the parts I needed to improve on this otherwise pretty well made machine.
The first pic is the small filter (with the cover removed) that came with the machine.
The second pic is my red neck engineering fix. I know that a good bit of the noise from a compressor comes from the intake side, especially that low frequency rumble. So what you see is a muffler for a 7.5 HP gasoline engine with a filter from a shop vac attached, along with a few pipe fittings. (Please don't laugh, I know how hockey it looks.)
Since I'll be putting it out side, the last pic is the assembly complete with a cover for the filter, a plastic paint bucket ( no laughing please).
Anyway, the compressor won't be starving for air from a clogged filter and although the machine is still not the quietest one in the shop, I probably lowered the noise level 10 to 12 bd and changed the frequency to something much less offensive. Not to bad for $18 in parts and about 20 minutes of my time.
OK now you can laugh. Perry
