The filter box is one of the important pieces of equipment in HVAC systems, used for air filtration in environments such as hospitals, medical centers, pharmaceutical and chemical industries, microelectronics industries, medical equipment, laboratories, and research centers. The primary purpose of using filter boxes is to maintain air quality inside sections, and to reduce the risk of transmission of contaminants.
Filter boxes usually include an air filtration system so that the incoming air to various sections is filtered and purified. These filter boxes use different types of filters, including HEPA and suspended filters, depending on the type of pollutants, and are capable of removing dust, suspended particles, and various chemical vapors from the air.
