Donaldson, PGI Cooperate On Filter Bag Media

The Donaldson Co. Inc., Minneapolis, has teamed up with North Charleston, S.C.-based Polymer Group
Inc. (PGI) for the production of industrial filter bag media.

PGI’s Durapex nonwoven fabric, made using PGI’s APEX® process, will be used by Donaldson
Torit® in its line of first fit and replacement baghouses.

Durapex was designed to meet the Environmental Protection Agencys Air Quality Standard, which
specifies a 2.5-micrometer particulate matter limit.

“Teaming up with PGI enables us to deliver industrial air filtration solutions that offer
superior value to our customers,” said Steve Groves, global product director, Donaldson Torit.
