What are the detection methods for high-efficiency filter H13?

    High-efficiency filter H13 mostly uses glass fiber filter paper as the filter material and is installed at the end of the purified air-conditioning air supply system. The installation of the high-efficiency filter must have reliable sealing measures and be easy to detect and replace leaks. The detection of high-efficiency filter filters What are the methods? What are the influencing factors?
    High-efficiency filter H13 filtration detection method:
    1. The method of absorbing flames
    2. DOP method
    3. Counting scanning method
    4. Photometer scanning
    5. Oil mist method
    6. Fluorescence method
    7. Variable air volume leak detection
    8. Smoke leak detection
    Generally speaking, its influencing factors include humidity and dust conditions in the production workshop, continuous and intermittent operation modes of the air conditioning system, maintenance of factory facilities, etc., which will affect the service life of the high-efficiency filter. Therefore, if it is general It is indeed difficult to set a replacement cycle, and there are no specific requirements in GMP standards.
    Generally, enterprises make decisions after conducting evaluation and testing based on their actual situation. The resistance of the sub-high-efficiency filter has exceeded the rated initial resistance by 100Pa, or is equal to 2x the design or operating initial resistance (3 times for low-resistance and sub-high efficiency) for more than 1 year. If it exceeds the standard, replace it at any time.
