🔍 How is a filter's efficiency measured?
One of the most widely used methods to evaluate filtration performance is the Multipass Test.
During this test, a controlled amount of contaminant is introduced into the fluid and continuously circulated through the filter. Advanced particle counting instruments then measure contamination levels both upstream and downstream of the filter.
By comparing these results, engineers can accurately determine the filter's particle retention capability and verify whether it meets the required performance standards.
At Filtrec, rigorous testing ensures that every filter delivers reliable protection, enhanced equipment performance, and extended service life.
