How do i quiet my blower??

[Eric Mims]

YES I AM YELLING. I ASSUME YOU CAN HEAR MY LOBE BLOWER FROM THERE!!!

all kidding aside, this thing is LOUD. I put a muffler on it and it helps, but it is still loud (it is currently under the machine). Should I try to build a box around it and the motor, and if so, use MDF/PLywood, insulate it somehow, multiple wall layers, air spacing? any ideas guys?

What about the unit/motor getting hot? It is way too loud to use as is for long.

It may be possible to put it in the back room in an enclosure of sorts and run a long PVC pipe back there (about 30'+).

what do you think?

mine is next to the machine and is under a box yet has airflow

get some ear muffs

oh believe me, I have the highest rated ear muffs sold at msc. It's way too loud right now. I can work in there, but it's too loud for the neighbors I'm sure. Definitely couldn't work at night.

well the lobe blower vacuum pump was way too loud to use in the shop (think 5 shopvacs going 10' away) and I didn't have room to box it in under the table where I had mounted it. PLus the exhaust really needed to be sent outside. So I extended the PVC piping into the back room and mounted the motor and pump inside an enclosure I built from MDF and 2" thick Corning 703. I shot the exhaust outside through the muffler mounted on the side of the building. Well, this was quite nice now on the inside of the shop, but now it was screaming outside! So over the past 2 rainy afternoons, I built a double baffle box that attaches to the outside of the shop, completely encompassing the muffler, and extended through a baffle maze, forcing the air to make zig zag turns around 4 'walls' covered in 703 insulation.

the thing is quieter than my AC unit now! Only thing I have to monitor is possible heat build up inside the box.. but that 703 fiberglass insulation is good at handling high heat.
