Dunham-Bush Air Cleaning System: Solution to eradicate viruses in the air

Air Handling Unit (AHU) is often used to regulate and circulate air as part of a heating, ventilating, and air-conditioning (HVAC) system. The basic structure of an AHU usually consists of a large metal box containing a blower, heating or cooling coils, filters and dampers. The basic function of the AHU is to take in fresh air, re-condition it to the required temperature and supply it to a building. AHU also remove the exhaust air and thus creates an acceptable air quality to the building. In Buildings where there is high level of hygienic requirements, AHU can help to improve the indoor air quality (IAQ) of the building with the addition of various air filtration accessories and air cleaning system. In fact, AHU can play the main roles in preventing the spread of bacteria and viruses in the building. DB Air Cleaning System – AHU with Five layers of filtration Dunham-Bush has introduced its new DB Air Cleaning System to fight against bacteria and viruses which includes the recent global pandemic COVID-19
