MERV-8 Pleated Panel Air Filters for Gas Turbine Applications Multi-Pleat GT filters are specifically designed for use as a prefilter in gas turbine applications to help extend the life of more expensive final filters. Durable and efficient, the Multi-Pleat GT is an ideal choice for many gas turbine applications. Low pressure drop/high efficiency. The Multi-Pleat GT carries a MERV-8 fractional efficiency rating in accordance with ASHRAE Test Standard 52.2 and has an initial pressure drop of less than .25" water gage. This combination of efficiency and low resistance to airflow make it a superior upgrade to conventional pleated filters and media pads.

Multi-Pleat XL11 - MERV 11 Extended Surface Pleated Panel Filters The Multi-Pleat GT-HD is a heavy-duty pleated panel filter designed for use in gas turbine applications where filter durability and extended life are of primary concern. The Multi-Pleat GT-HD pleated air filter is designed to offer superior performance in the most extreme conditions.The heavy-duty construction of the Multi-Pleat GT-HD helps to insure product stability, high dust holding capacity, and low pressure drop in many gas turbine applications. The Multi-Pleat GT-HD uses a heavy .056" beverage-board frame, which is twice as thick as normal pleated filters on the market. The heavier frame helps maintain the filter’s integrity throughout its service life even in most high moisture applications. High-loft synthetic media is bonded to a rust resistant heavy-duty expanded metal backing. The heavy-duty expanded metal backing helps maintain the pleat structure to ensure full media utilization during operation. Two media options: Standard and high efficiency.

MicroMAX Minipleat Filter The Koch MicroMAX is an extended surface minipleat filter designed for use in a wide variety of air filtration systems. The MicroMAX offers a unique combination of high efficiency and low pressure drop making it the ideal filter for use in any standard HVAC system. The added advantages of its compact 4" depth and lightweight-yet-rigid construction also give the MicroMAX unsurpassed capability to perform in more specialized and difficult applications. MicroMAX Filters are available with standard beverage board frames or with galvanized steel frame. Steel framed MicroMAX filters are available with no header or with a single upstream header.

DuraMAX V-Style Minipleat Filter The DuraMAX is a rigid, extended surface air filter, engineered to provide maximum performance and prolonged filter life cycles, even in the most difficult environments. The durable, rugged, construction of the DuraMAX make it the filter of choice in filtration systems with high velocities or variable air volumes. DuraMAX Filters are constructed with a 100% plastic frame and are completely incinerable. DuraMAX provides an unequaled combination of low pressure drop and high efficiency through the use of our unique minipleat design. This high capacity minipleat design allows a nominal 24x24x12 filter to incorporate 194 square feet of filter media. This increased extension of the media surface area insures low pressure drop, and low resistance to airflow means lower energy costs to the user. Another benefit of the increased media area is extremely high Dust Holding Capacity, which significantly prolongs the service life of the filter. Fewer filter changes translate into substantially reduced maintenance and disposal costs. In order to meet the wide range of requirements found in today's complex air filtration systems, DuraMAX filters are available in five ASHRAE efficiencies, 65, 75, 85, 95, and 98%. The Filter is offered in three standard sizes, 24x24x12, 20x24x12, and 12x24x12. Single or double header configurations are available.

Maxi-Cell Extended Surface Filter For High Velocity Applications The Koch Maxi-Cell is a high efficiency, extended surface air filter designed for use in gas turbines and other applications where higher-than-normal airflow velocities exist. A step up from the Multi-Cell, the Maxi-Cell is constructed with faceguards on both sides of the filter and includes other features which make the Maxi-Cell a superior filter in any application where extreme conditions require additional filter strength and reliability.

Fiberglass Air Filter Media Rolls and Pads Koch Supergrade Fiberglass Air Filter Media is available in a wide range of pad and roll sizes. Because all air filtration systems are different, one standard media cannot meet every requirement. With three media depths to choose from it is possible to find the right media for any fiberglass application. Contact your Koch representative for recommendations on your system.
