Used measuring the raw material’s filtration efficiency and initial pressure drop values at diffirent air velocities.
• Different oils (Emery 3004, Paraffin etc.) and salt (NaCl) can be used as the source of liquid and solid aerosols in the tests.
• Pre-tests are made for raw materials manufactured by different suppliers to make detailed comparisons. The selection of the best quality raw materials is supported by the test results obtained here.
• Raw material quality control tests are carried out with this system before production.
