David01,
I have a similar small workshop problem occupied by a loud CV1800. Rather than permanently mounting the cyclone, I built a compact enclosure (from 2X 3 lumber and ½” plywood) on castors. The enclosure contains the Motor, Blower Housing, Cyclone Body, and Dust Collection Bin. The Blower Housing Transition extends beyond the enclosure and the filter stack sets outside the enclosure. The enclosure measures 29-1/2” wide and 27” deep. The overall footprint, including the filter stack, is 27” deep x 53”.
This enclosure allowed me to surround the cyclone unit with sound absorbing insulation. I used 2 products to abate sound; R13 (3/12”) Ultratouch Denim Insulation (15” wide bats) and UltraSonic Sound Panels, which are rigid sound absorbing 12” x 12” x 1” panels. Both products offer affordable sound absorbing properties. Ultratouch Denim Insulation can be ordered from Lowes or Home Depot on-line and shipped to the store free. UltraSonic Sound Panels is available on-line at Home Depot. Also, rigid sound panels can be found at
http://www.soundproofcow.com/Acoustic-Cotton. Others have used Roxul Safe and Sound, but the Denim insulation is cotton, not mineral wool, and I think has better sound absorbing properties than Safe and Sound.
I packed the Denim insulation around the cyclone and around the Blower Housing. I used UltraSonic Sound Panels on top of the Blower Housing and around the motor because it is rigid and thus stays where I put it. Most importantly, I left a 3” wide air channel around the motor and two (front and back) 3” wide channels on top of the Blower Housing leading to the lower motor vent, to allow air to freely circulate around the motor. I used 3 layers of Sound Panels on top of the Blower Housing and on top of the Motor Mounting Plate.
I wrapped the Blower Transition with Denim insulation and then wrapped 3 mil plastic around the Denim insulation. This wrapping holds the Denim Insulation in place.
Also, to reduce sound bouncing off nearby walls, I hung insulation on the walls near the cyclone.
