• Dual-layered filter media
• Low pressure drop
• Superior efficiency
• High dust holding capacity
• Multi-Pleat XL11™ is produced with a highly specialized, dual layered 100% synthetic media, developed by Koch filter Corporation specifically for use in extended surface air filters
• New media is composed of an upstream electrostatically enhanced layer and a downstream mechanical layer
• Dual-layered construction of Multi-Pleat series XL11 overcomes a common problem found in single-layered electrostatically charged filters
• In filters produced with single-layer media, the effectiveness of the electrostatically charged media decreases over time as the filter becomes dirty and the charge dissipates
• Unique dual-layered media design of the Multi-Pleat XL11™ greatly reduces this problem
• Effectiveness of the electrostatically enhanced E-layer decreases, the downstream mechanical M-layer takes over
• M-layer steps up to provide better continuing overall performance and excellent dust holding capacity
• Standard capacity XL11-SC filters provide a combination of efficiency, economy, and excellent overall performance
• Standard capacity XL11-SC filters are an excellent choice in applications where filter change schedules are based on preventive maintenance schedules
