Abstract

ISO 29461 specifies methods and procedures for determining the performance of particulate air filters used in air intake filter systems for rotary machinery such as stationary gas turbines, compressors and other stationary internal combustion engines. It applies to air filters having an initial particle efficiency up to 99,9 % with respect to 0,4 µm particles. Filters with higher initial particle efficiencies are tested and classified according to other standards (e.g. EN 1822). These procedures are intended for filters which operating at flow rates within the range 0,25 m3/s (900 m3/h) up to 1,67 m3/s (6000 m3/h). ISO 29461-1:2013 refers to static (barrier) filter systems but can be applied to other filter types and systems in appropriate circumstances. Two methods of determining the efficiency are used in ISO 29461-1:2013: particulate efficiency (measured with respect to particle number and size); gravimetric efficiency (percentage weighted mass removal of loading dust. Also a flat sheet media sample or media pack sample from an identical filter is conditioned (discharged) to provide information about the intensity of the electrostatic removal mechanism. After determination of its initial particle efficiency, the untreated fil
