I have a 5HP Oneida Dust Gorilla that I purchased used, it is much more dust collection than I ever wanted or needed, but for $1,000 total, I could not pass it up. And it came with some pipping and fittings, enough that I had to buy very little to install. But the thing is NOISY, I knew that and expected it when I got it. Now I find myself not turning it on sometimes for one or 2 cuts. The plate on the motor says to avoid turning that motor on/off more than 3 times an hour (I think it was 3) so when I turn it on, I tend to leave it on and I hate wearing hearing protection in the garage if I am not actively cutting or routing or ?
So, how do I quiet the thing down. I have purchased Oneida's muffler, it will arrive in 2 weeks. I assume that will help.
I really could not place it outside, neighbors bedroom window is 12 ft. from my garage wall and I felt that would be noisy for them at night even with soundproofing.
I was thinking of building a cabinet for it and soundproofing that, but when I did that for my air compressor, I ended up overheating the compressor at first, I had left ventilation but not enough. I have the DC placed as high as I can go in the shop, the motor is about 10ft off the ground and the barrel is on the ground with about 2ft of hose since the DC is up higher than normal. I placed it that high to get the best straight shot along the ceiling for the pipes. I have 9ft walls with scissor joists so about 12ft in the middle of the garage. I was thinking I could enclose the barrel and hose, that will not cause a heat issue but it seems like that would cause the least noise reduction. If I enclose the motor, it will get too hot, that leaves the filter area.
I can't be the first to want to do this, but when I searched, I didn't get any good results so I think my search keywords just were bad.
