Press release -
New Standard: ISO 29461-2:2022, The first international standard for filter performance in fog and mist environments
ISO, the global committee of industry experts that release international standards, has recently published its latest turbomachinery-specific standard for air intake filters, ISO 29461-2. This is the first official standard for turbomachinery applications that rates a filter’s endurance in fog and mist environments, and determines a filter’s resistance to water penetration.
Prior to this standard, filter manufacturers applied in-house testing methods to measure hydrophobicity, making it difficult to compare filters. ISO 29461-2 standardizes the testing procedure, requiring filters to be measured and rated according to the following test parameters:
- The test procedure is 3 hours
- The filter must have a pressure drop less than 1000 Pa (4” w.g.)
- There cannot be any measurable water downstream of the filter
- Optional test method if a filter is to be labeled “Hydrophobic”: use a water dye to confirm that there is no water downstream of the filter.
Measuring a filter’s hydrophobicity, or resistance to water penetration, is critical for turbomachinery applications. Gas turbines, for example, can be subjected to large quantities of water. If a filter is not hydrophobic, or lacks drainage capabilities, water can carry over contaminants that are harmful to the gas turbine. The result is output loss, higher heat rate, increased maintenance requirements and higher CO2 emissions per MWh produced.
In September 2021, the ISO committee also released the first international standard for rating the efficiency of turbomachinery air intake filters, ISO 29461-1. Using a combination of both the ISO 29461-1 and ISO 29461-2 standards, turbomachinery operators can better select filters that will best protect their assets from part and output degradation. For example, for most applications exposed to heavy water concentrations, Camfil recommends filters that are high efficiency T10+ according to ISO 29461-1:2021 and hydrophobic according to ISO 29461-2:2022.
For an in-depth comparison of different filters, Camfil offers a Life Cycle Cost (LCC) Analysis to determine how filters will perform according to your specific local site conditions and operations. Learn more about the LCC at www.Camfil.com/LCC.
Camfil will be hosting a webinar on September 21st at 9:00am EST. During this webinar, a detailed explanation of the ISO 29461-2:2022 will be presented. Register Here.
