• Moisture-resistant beverage board frame maintains rigidity even in high humidity environments 100% mechanical media provides high efficiency, excellent dust holding capacity throughout the filter's lifecycle Rust-resistant galvanized-dipped expanded metal support grid is totally laminated to media to insure even pleat spacing and structural support Pleats are bonded to frame to guarantee consistent pleat configuration and total media utilization Frame is double walled with reinforced corners to insure rigidity in the toughest applications 30% more media high capacity XL8-HC filters are similar in construction to the standard capacity but have the added advantage of approximately 30% more media The additional media results in extended filter life, making the XL8 HC the ideal filter for use in filtration systems where filter change schedules are predicated on recommended final pressure drop readings

The multi-pleat XL8 media is produced with an optimal blend of highly specialized fibers, developed by Koch Filter Corporation specifically for use in extended surface air filters. Developed to deliver a "one of a kind" performance, this specialized media operates on mechanical filtration principles which provide high efficiency, low pressure drop and high dust holding capacity. The Koch multi-pleat XL8 maintains a MERV 8 performance rating before and after conditioning steps when tested in accordance to ASHRAE test standard 52.2-2007 and 52.2- 2007 Appendix J.
