Description
Koch Filter® Extended Surface Pleated Panel Filter, Series: Multi-Pleat XL11™ SC, 18 in Width, 4 in D, 24 in Height, MERV: 11, 900 to 1875 cfm, 150 deg F, Paperboard Frame, 60 to 65% Efficiency, 0.13 to 0.45 in WG Initial Resistance, 1 in WG Final Resistance, 100% Synthetic Media, Yellow, Domestic
Features:
- 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
- 17.4 sq-ft media
