Maximum Area in Every Pocket: Medium Efficiency Filter Bags
The Medium Efficiency Filter Bags (Pocket/Bag Filter) are the workhorse of HVAC and cleanroom medium-stage filtration — multiple filter pockets (bags) arranged on a rigid frame to multiply the filtration area within a compact housing. At F5-F9 efficiency, these bags capture medium particles (≥1-2 µm) that pass the primary stage, protecting downstream HEPA filters. With high dust-holding capacity, low resistance, and easily replaceable bags, they are the dependable medium-stage filter choice for cleanroom air systems, air handling units, and HVAC equipment.
Multi-Pocket Design — Multiplied Filtration Area Multiple filter bags arranged on a rigid frame multiply the filtration area within a compact housing — maximizing dust-holding capacity and airflow. Efficient Medium-Particle Capture (F5-F9) Captures medium particles (≥1-2 µm) at F5-F9 efficiency levels (EN 779 / ISO 16890) — removing particles that pass the primary stage. High Dust-Holding Capacity — Extended Service Life The large total bag area provides high dust-holding capacity — extending service intervals and reducing replacement frequency. Low Initial Resistance — Energy Efficient The multiplied filtration area delivers effective capture at low initial resistance — balancing performance with energy efficiency. Protects Downstream HEPA Filters By intercepting medium particles before the HEPA stage, the filter bags extend the life of the most expensive filters in the chain. Easily Replaceable Bags The filter bags are individually replaceable or replaceable as a complete assembly — simplifying maintenance and reducing downtime. Wide Application Suited to cleanroom air systems, air handling units (AHU), HVAC equipment, pharmaceutical facilities, and electronics plants.
