Multi-pocket bag filters are air filtration devices that use multiple pockets to increase the surface area for filtering air in HVAC systems, clean rooms, and industrial applications. They are made from synthetic or fiberglass media and are highly efficient at capturing fine particles like dust, pollen, and other airborne contaminants.
- High filtration efficiency.
- Large surface area.
- Low pressure drop.
Description
- Aerodynamic, Tubular Pocket Spacers and Wedge-Shaped Filter Design channel the air for particulate loading throughout the depth of the pocket and minimum air flow resistance.
- Self-Supporting Pockets stay rigid in turbulent airstreams and during turbine shutdown.
