Clarcor Inc, was organized in 1904 as an Illinois corporation and in 1969 was reincorporated in the State of Delaware. The Company conducts business in three main industry segments: Engine/ Mobile Filtration; Industrial/ Environmental Filtration; and Packaging. The Company's Engine/Mobile Filtration segment sells filtration products for engines used in stationary power generation and for engines in mobile equipment applications, including trucks, automobiles, buses and locomotives, and marine, construction, industrial, mining and agricultural equipment. The products in the Engine/Mobile Filtration segment include oil, air, fuel, coolant, transmission and hydraulic fluid filters which are used in a wide variety of applications and in processes where filter efficiency, capacity and reliability are essential. The Company's Industrial/Environmental Filtration segment includes liquid process filtration products and air filtration products and systems used to maintain high interior air quality and to control exterior pollution. The segment's liquid process filtration products include specialty industrial process liquid filters; filters for pharmaceutical processes and beverages; filtration systems, filters and coalescers for the oil and natural gas industry; filtration systems for aircraft refueling, anti-pollution, sewage treatment and water recycling; bilge water separators; sand control filters for oil and gas drilling; and woven wire and metallic products for filtration of plastics and polymer fibers. These filters use a variety of string wound, meltblown, porous and sintered and non-sintered metal media, woven wire and absorbent media. The segment's air filtration products represent air filters and cleaners, including antimicrobial treated filters and high efficiency electronic air cleaners. These products are used in commercial buildings, hospitals, factories, residential buildings, residences, paint spray booths, gas turbine systems, medical facilities, motor vehicle cabins, aircraft cabins, clean rooms, compressors and dust collector systems. The Company's Packaging segment is conducted by a wholly-owned subsidiary, J.L. Clark, Inc. Products in both the Engine/Mobile Filtration and Industrial/Environmental Filtration segments are sold primarily through a combination of independent distributors, dealers for original equipment manufacturers, retail stores and directly to end-use customers such as truck and equipment fleet users, manufacturing companies and contractors. The Company's operations are subject to U.S. and non-U.S. environmental laws and regulations governing emissions to air; discharges to water; the generation, handling, storage, transportation, treatment and disposal of waste materials; and the cleanup of contaminated properties.
