Multi-Pleat XL11-HC Multi-Pleat XL8 MERV 8 Extended Surface Pleated Panel Filter

Multi-Pleat XL11-HC

The Koch Multi-Pleat XL11-HC is a medium efficiency extended surface pleated panel filter, engineered to provide higher initial efficiencies and better overall performance than standard pleated filters.

The Multi-Pleat XL1-HC carries a MERV 11 fractional efficiency rating in accordance with ASHRAE Test Standard 52.2-2017.

The MERV 11 efficiency provided by the Multi-Pleat XL11-HC make the filter an excellent upgrade from disposable filters and ordinary pleated filters in applications such as hospitals, laboratories and pharmaceutical environments.

Multi-Pleat XL11-HC Construction

The Multi-Pleat XL11-HC is produced with a highly specialized, dual-layered 100% synthetic media, developed by Koch Filter specifically for use in extended surface air filters. The new media is composed of an upstream electrostatically enhanced layer (the E-layer), and a downstream mechanical layer (the M-layer). The dual-layered construction of Multi-Pleat Series XL11 overcomes a common problem found in single-layered electrostatically charged filters. In filters produced with single-layered media, the effectiveness of the electrostatically charged media decreases over time as the filter becomes dirty and the charge dissipates. As the effectiveness of the electrostatically enhanced E-layers decreases, the downstream mechanical M-layer takes over.

High Capacity XL11-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 XL11-HC the ideal filter for use in filtration systems where filter change schedules are predicated on recommended final pressure drop readings.
