Air intake filter systems for rotary machinery. Test methods - Static filter elements Ingestion-build-47553 the chain produced to BS1 Scope 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 m particles. Filters with higher initial particle efficiencies are tested and classified according
