AHU Casing and Filter Standards as per EN 1886
EN 1886 standard is a part of a series of standards for Air Handling Units used for ventilation and air conditioning of buildings for human occupancy. It considers the mechanical performance of an Air Handling Unit as a whole and will be supported by a standard for sections and components. This standard specifies test methods, test requirements and classification for Air Handling Units which are supplying and / or extracting air, via duct work for ventilating / conditioning a part or the whole of the building. Except for the thermal and acoustic performance of the casing, the test methods and requirements are applicable to both complete units and any separate sections. Filter bypass test is not applicable to the testing of HEPA filters. The test method for the thermal performance of the casing is applicable to the comparison of different constructions but not to the calculation of thermal losses through the casing or the risk of condens...
