Service life of high-efficiency filters (general standards for clean rooms)
\nBased on three scenarios: normal operation conditions, harsh conditions, and DOP air supply outlet liquid tank high-efficiency, the industry practical standards are directly provided:
\n1. Ordinary clean rooms (pharmaceutical \/ electronic workshops, conventional ventilation)
\nH13\/H14 high-efficiency filters: Normal use for 1 to 2 years
\nWith intact primary and secondary filters at the front end: Available for 2 to 3 years
\n2. Poor conditions, high dust, large fresh air volume
\n(Noisecell workshops have a lot of dust production, no good pre-filtering, frequent opening)
\nService life is significantly shortened: 6 months to 1 year
\n3. Operating rooms, aseptic GMP workshops, biological laboratories
\nDOP liquid tank high-efficiency air supply outlet filters
\nRecommendation: Replace every 1 year
\nIf the pressure difference rises rapidly or the DOP leak test fails: Replace immediately
\n4. Whether to replace or not is not determined by time\uff0c but by 3 indicators
\nFinal resistance reaches 2 times the initial resistance (the most standard basis)
\nDOP\/PAO leak detection is\u4e0d\u5408\u683c\uff0c there is leakage
\nCleanliness does not meet standards\uff0c dust particle exceeds limits
\n5. Key to extending service life
\nEnsure primary filters are replaced within 3 to 6 months\uff0c secondary filters within 6 to 12 months
\nMaintain positive pressure in the clean room\uff0c reduce the entry of external dust
\nAvoid frequent start-stop and sudden strong blowing with large air volume<\/p>","protected":false},"excerpt":{"rendered":"
