	What can you expect to learn from a Pneumafil Filter Life Expectancy Test? Pneumafil will perform the specific tests listed below as part of the overall evaluation. To learn more about how and where we perform tests, click here for a quick tour of our filter testing lab (movie). 1. Pressure Drop vs. Flow Rate Pneumafil performs pressure drop vs. flow rate testing on the filter set as received in its own test duct. The pressure drop vs. flow curve in the current condition is compared to the known or estimated curve in the new and clean condition. If filters show a significantly higher current pressure drop vs. the initial clean condition, it is probably nearly time to change them. If the filters were pulsed in service and the pressure drop cannot be reduced by the cleaning system in the filter house, then they almost certainly must be changed. 2. Mullen Burst Pneumafil performs a Mullen Burst test on the filter media from the sample filters. The filter is cut open and a sample of the filter media is tested on a Mullen Burst tester, which measures the overall strength and resistance to bursting. Again the measured value is compared to that of new media or to an estimated value for new media. Mullen values can be obtained in both the dry and wet condition for the media. Wet values are lower for media that include cellulose fibers. Low Mullen burst strength values indicate media that is old or weak and could fail in service allowing bypass of unfiltered air. Burst media could even allow foreign objects like media pieces to be ingested into the turbine compressor. Mullen Burst Tester 3. Permeability Pneumafil performs a permeability test on the filter media that is removed from the sample filter. This is referred to as a Frazier permeability test and is reported as the amount of air that will pas through a one square foot sized sampleat the specific pressure drop of 0.5 inches w.g. Again the measured value is compared to the value of new and clean media. Low Frazier values may indicate media that is ‘blinded’ or clogged with fine particulate (like hydrocarbon soot from diesel or other exhaust) that cannot be removed by the pulse cleaning system on the inlet filter house.
