Air Filters and Chemical Filtration
High-Airflow Medium-Efficiency Filter
A reinforced extended-surface filter built to process higher air volumes while maintaining open channels through a deep supported media pack.
- High Face Velocity
- Reinforced Metal Cell
- Open Deep-Pleat Channels
- Large Dust Storage
Product Introduction
The high-airflow medium-efficiency filter combines a deep extended-surface media pack with rigid galvanized or aluminized-steel cell sides, protective faceguards and structural support straps. Corrugated separators or stabilized pleat spacers maintain open channels through the full depth of the pack as face velocity rises. A high-loft microglass or synthetic medium stores particles through its depth, while the rigid header resists the pulsation and turbulence found in large air handlers and process-air inlets. This construction emphasizes mechanical stability and airflow capacity rather than minimum cabinet depth.
Key Features
Corrugated separators preserve full-length channels under turbulent inlet conditions.
Metal faceguards and cross straps protect the pack from bowing and handling damage.
A high-strength enclosing cell keeps the gasket plane flat under sustained differential pressure.
Customer Product Concerns
High-volume systems expose filter packs to turbulence, pulsation and structural loads that ordinary medium filters may not withstand.
Increasing airflow sharply raises pressure drop through a small media pack.A full-depth extended-surface pack lowers velocity at the media and preserves open flow channels.
Turbulent inlet air bows the pleats and damages the pack perimeter.Corrugated separators, faceguards and support straps share the load across the rigid cell.
Repeated fan starts loosen the internal pack-to-frame bond.Deep polyurethane potting anchors the entire media perimeter inside the metal cell.
A distorted header leaves compression gaps along the filter bank.Reinforced galvanized cell sides maintain a flat gasket surface at high operating pressure.
Typical Applications
