ISO 29461
International test standards for turbomachinery air intake filters

ISO 29461: Turbomachinery air intake filter standards

ISO, a global committee of industry experts that release international standards, has published the first turbomachinery-specific standards for air intake filters, ISO 29461-1, ISO 29461-2 and ISO 29461-3.

ISO 29461-1 reports the efficiency and dust holding capacity for turbomachinery air intake filters. ISO 29461-2 rates a filter’s endurance in fog and mist environments, and determines its resistance to water penetration. ISO 29461-3 assesses a filter's mechanical integrity under high pressure through burst testing.

These standards present a uniform method for testing filters that enables turbomachinery operators to more easily compare and select air inlet filters.
