According to
EN 1822-4 High efficiency air filter (EPA, HEPA and ULPA) Part 4: Determining leakage of filter elements (scan method)
GB/T 6165 High efficiency air filter performance test method: Efficiency and resistance
Advantages
1. It adopts intelligent component control and is composed of PLC, HMI and XYZ axes. Software interface is simple and clear, easy to operate. 3-axis control realizes automatic detection.
2. Adopt point-by-point scan method and has leakage point rescan function. Which can accurately locate the leakage point position, and reflected in the test report, it is convenient for users to repair the leakage point.
3. Customized isokinetic sampling head and test template can meet the test requirements of different product specifications.
4. Adopt the main road bypass test principle, meet the requirements of continuous product test. Save the time of preparation and improve work efficiency.
5. Aerosol generator adopts Laskin nozzle, adjust the aerosol concentration automatically.
6. Adopt high-precision imported differential pressure transmitter and Lighthouse high-precision laser particle counter to ensure accurate and stable test results.
7. Adopt well-known brand fan, equipped with a high-efficiency filter group to ensure the cleanliness of the air flow. Combined nozzle ensures the accuracy of test results under different air flow. Equipped with flow rectifier to ensure the uniformity of air flow.
8. The test report is automatically generated after the test is completed, all test data will be reflected in the report. Users can choose to print directly or save it.
Applications
It is suitable for the filter efficiency and resistance test of HEPA filters with grade E10-U15.
It also can detect the leakage of filter elements by scan method.
