Build your own plenum
Plenum box can be constructed of plywood or metal.
Oneida Air Systems sells 22 gauge galv. plenum boxes.
The filter medium is a 16 ounce polyester felt which has
been singed inside to help release caked dust.
For the tube style filters, a 12” dia. ring thimble (Part #
FAZ000000) is needed for each filter. The plenum box and
the ring thimbles are suspended above the floor at a height
that will allow for a 5 gallon plastic bucket and tube filter to
fit properly underneath.
A well sealed plywood box will make a good plenum for
air distribution through the tube filters. Use plywood for the
plenums. Cut 12” dia. holes in the bottom of the box (spaced
2 - 3” apart), so that the ring thimbles fit snugly. The rings
should not be able to slide through the holes. Bend Ring
Thimble tabs then apply duct sealant or caulk around the
edge of the ring thimble. Use sheet metal screws to secure.
Be sure to remove any sharp edges from the bucket or
ring thimble that may abrade the filter. Slide the filter over
the thimble past the raised bead. Secure with a band clamp.
Slide the bottom of the filter over a five gallon plastic bucket.
Secure with a band clamp or strong bungee (shock cord).
Be sure filter is not loose or moving around when the system
is on. This could lead to wear on the filter.
With the use of a cyclone pre-separator, the buckets will
not need emptying very often, but do need to be checked
occasionally. Simply lift the bucket, the weight will indicate
how full the bucket has become.
