Series 331Y PA

22 Gram Fiberglass Paint Arrestor

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 parti- cles.

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 vir- tually 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.
