Cut our change-out frequency
Dust holding capacity is noticeably better than what we were using, so we're getting longer intervals between changes.

The PBR-AG Pre-Pocket Filter uses four non-shedding polyester pockets in a stainless-steel frame to capture large particles and salt aerosols before they reach high-efficiency filters. With high dust-holding capacity and performance up to 80°C, it is suited to humid, salt-laden offshore and coastal environments. It is also an OEM-equivalent replacement for Altair-specified systems.
Construction
The four pockets use non-shedding, thermally bonded polyester in a robust stainless-steel frame with a 22mm header. The standard 4-pocket size is 597 × 597 × 400mm, with other sizes, clips and seals available for bank installations.
