Air Filtration Units

About this category

This class serves treating air per the application. Unit configurations vary by contaminant type and facility: some may be portable units for zone-air treatment, ceiling-mounted units for larger facilities, or units integrated with central HVAC systems. Technologies in use vary by model: some units may include mechanical filtration, activated-carbon filtration, or high-efficiency filtration. A distinction is maintained between mechanical filtration — which addresses separation of airborne particulates — and gas or vapor treatment technologies that may rely on adsorption media or chemical media depending on the target contaminant and the unit design. Ultraviolet and ionization technologies are treated as air-treatment technologies rather than mechanical filter media in the same sense, and their availability is defined by product design. Technical note: technology suitability for the application requires assessment of the target contaminant; a single technology is not assumed suitable for all applications. Uses: printing facilities, pharmaceutical manufacturing facilities, precision manufacturing facilities, hospitals, research laboratories, food-industry facilities, and electronics-assembly facilities. Operating considerations: selecting the unit based on contaminant type and target area, maintaining filters or media per the manufacturer schedule, and integration with the on-site ventilation system. Model specifications, treatment technology, flow capacity, and installation requirements are reviewed in the product documentation before selection.
