FOR USE AS AN EXHAUST FILTER

Series 331Y fiberglass media is constructed using 22
grams of fiberglass media per square foot. The fibers
are formed into progressively denser layers. Fiberglass
media is ideal for capturing paint overspray due to its
ability to maintain an open outer layer. It is this initial
outer layer that allows the entire depth of the media to
hold paint particulate and not “surface load” like many
overspray collectors.

The media is solid yellow and has a skin backing on the
downstream side. This skin backing helps prevent the
media from sagging when particulate is captured and
provides a final barrier against small overspray parti­cles.

Fiberglass media is ideal for users with little or now
storage area. The media has 100% memory when
compressed, therefore the rolls are tightly wound and
the pads are available in vacuum packed boxes.

Fiberglass media comes in pad or roll form. The rolls
are available in 300 foot lengths. The pads come in vir­tually any size, but 20x20 and 20x25 pads are most
typical in crossdraft and semi-downdraft booths. A grid
is needed to hold the pad which is standard in most
booths. If you downdraft booth uses a pit, measure the
width of the pit to find the appropriate roll, or check our
booth guide. To change the media, simply unwind the
roll to the proper length and cut a pad.
