Ducts are used in heating, ventilation, and air conditioning (HVAC) to deliver and remove air. The needed airflows include, for example, supply air, return air, and exhaust air. Ducts commonly also deliver ventilation air as part of the supply air. duct with less than 0.75 mg/100m 2 is considered to be clean, per the NADCA standard. A Hong Kong standard lists surface deposit limits of 1g/m 2 for supply and return ducts and 6g/m 2 for exhaust ducts, or a maximum deposit thickness of 60 Âµm in supply and return ducts, and 180 Âµm for exhaust ducts.
