PURE PERFORMANCE Provides effective removal of odors and Volatile Organic Compounds (VOC). Constructed with premium grade coconut shell carbon Available with specially impregnated adsorption medias As worldwide Indoor Air Quality specifications become more demanding, gas phase adsorption is quickly becoming a major factor in commercial and industrial air filtration systems. The DuraPURE is an excellent high performance solution in applications such as airports, industrial facilities, chemical plants, office buildings, and a wide variety of other air filtration systems. The Koch Filter DuraPURE is an extended surface carbon filter which utilizes premium grade granular 60% activated carbon. DuraPURE's unique V-shaped frame holds up to 26 pounds of activated carbon in a single 24x24x12 filter, which insures maximum VOC and odor removal in any commercial or industrial application. Two Capacity Levels and Three Standard Sizes To meet the tough requirements of today's complex air filtration systems, DuraPURE is available in three standard sizes, and two media capacity levels, Standard Capacity and High Capacity. Specialized Carbon Media DuraPURE is also available with specialized impregnated carbon media for removal of ammonia, hydrogen sulfide, and other dif-ficult-to-remove compounds. Consult your Koch Filter representative to find the appropriate DuraPURE model for your system.
