FOR USE AS AN EXHAUST FILTER
The 225T uses two distinct media layers sewn and welded
together to form the cube. The first media layer is a 1” white
single 15 denier polyester media. This polyester media is
treated on the inside with a special tackifier to help hold the
paint particles to the media 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 sur-
face 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 sec-
ondary level of protection against overspray. This second layer
of defense aids in decreasing maintenance on exhaust equip-
ment, 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 fur-
ther 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.
