Koch Filter 102-499-003 Multi-Pleat 14 x 20 x 1" Panel Filter

Koch Filter, 102-499-003, Multi-Pleat 14x20x1" Standard 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

Standard Capacity XL11 filters provide a combination of efficiency, economy, and excellent overall performance. Standard Capacity XL11 filters are an excellent choice in applications where filter change schedules are based on preventive maintenance schedules.
