FOR USE AS AN EXHAUST FILTER
The 425T uses two distinct media layers sewn and welded
together to form the cube. The first media layer is a 1.5”
white/green/white triple 45/15/6 denier polyester media.
This polyester media is treated on the inside with a special
tackifier to help hold the paint particles to the mediia as they
enter the filter. The second media layer is a tightly needled
1/4” 6 denier polyester media. This layer prevents the fine
particles from exiting the filter.
Cube filters have a distinct advantage over flat pads (more
surface area). An increase in surface area increases the
amount of paint that can be captured in a given area and
reduces the restriction to airflow. Cube filters are an ideal
choice as a secondary level of protection against overspray.
This second layer of defense aids in decreasing mainte-
nance on exhaust equipment, reducing fire hazards due to
exhaust buildup and decreasing the amount of overspray in
the environment.
cubes are available with 1, 2, or 3 pockets. Each pocket
further increases the paint holding capacity. There is also a
choice of self-sealing headers or 7/8” metal headers.
Each media pack is welded around a 9 gauge wire support
frame. The self supportive media is overlapping the frame
by 1/2”, allowing the excess media to work as a gasket
when the filter is installed.
