Filters are extensively used in industries where particulate free or sterile air is required. Certain production processes demand the clean air that HEPA filters provide. Applications range from filtration systems for factory, office and hospital air systems, as well as assembly areas where precision parts are assembled. These include aerospace, microelectronics, research and photoprocess laboratories. Food and beverage processing plants and pharmaceutical packaging systems are prime users of clean air systems. The applications are many and diverse depending on the contamination control required. We provide the lower prefilter and factory systems or the medium and high efficiencies for Laminar Flow Benches and Clean Rooms.
