Koch Filter, 102-500-001, Multi-Pleat 10x20x1" High Capacity MERV 11 Extended Surface Pleated Panel Filter
Features:
- Upgrade from the standard pleated filter
- MERV 11 rating
- Dual-Layered filter media
- Low-pressure drop
- High dust-holding capacity
- Superior Efficiency
The Koch Multi-Pleat XL11 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 XL11 carries a MERV 11 fractional efficiency rating in accordance with ASHRAE Test Standard 52.2. The filter will also provide an Initial Dust Spot Efficiency of 45%, and an Average Dust Spot Efficiency of 55-60% in accordance with ASRAE Test Standard 52.1. The MERV 11 efficiency ratings provided by the Multi-Pleat XL11 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 Construction
The Multi-Pleat XL11 is produced with a highly specialized, dual-layered 100% synthetic media, developed by Koch Filter specifically for use in extended surface air filters. The 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.
Media Area Capacity Level
High Capacity X11-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.
