Koch DURAMAX V-Bank Pleated Filters | Extended Surface for AHUs

Koch DURAMAX is the V-bank extended-surface pleated filter line for commercial AHUs with depth constraints. Where rigid Multi-Cell or pocket Multi-Sak filters won't fit, DURAMAX delivers extended-surface media area in a header-style configuration that drops into existing 12″ rigid filter tracks. DURAMAX 2v, 3v, 3vS, 4v, 4vS, 4vGT cover the standard MERV 11 through MERV 15 commercial range. DURAGLOVE adds a fabric outer-glove for high-debris environments. Standard Capacity and High Capacity (HC) variants for matching AHU CFM and pressure-drop budget. The right answer when a Multi-Cell rigid won't fit but pleated panels won't deliver enough service life.
