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 and ISO 29461-2.

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.

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