Building your own Filter Clean Out Box
(filtered systems only)
Note:
Filter Clean Out Boxes are available for purchase at www.clearvecyclones.com.
The only requirement for building your own filter clean out box is that it is airtight when
closed and has an opening to remove the dust collected.
1. Determine the height of your filter clean out box:
a. Measure the distance from the bottom of the 90° filter transition to the floor.
b. Subtract the height of the filter stack (68”) to determine the required height for the filter
clean out box.
2. Build the box out of ¾” plywood or MDF, nails and wood glue:
a. The recommended dimensions are 14” x 14” x the height determined in step 1.
b. The box should have a hole cut out of the top approximately 8-½” in diameter.
c. Cut a rectangular access opening on the front of the box for clean out purposes.
d. Build the cover plate larger than the access opening, to cover the opening in its
entirety. Use ½” thick by 1” wide gasket or weather stripping around the inside edge of
the cover plate for an airtight seal.
e. Use wood screws to secure the cover plate in place during use.
