Criteria for Judging the Replacement of High-Efficiency Filters (General for Clean Rooms, Simple and Direct)
\nThere is no need to memorize the years. Instead, focus on checking the pressure difference, leak detection, cleanliness, and appearance. Any one of these conditions being met requires replacement.
\n1. The most standard: Check the pressure difference (most commonly used and most accurate)
\nRecord the initial resistance (the pressure difference after the new filter is installed and stabilized)
\nWhen the final resistance \u2265 2 times the initial resistance \u2192 Replace immediately
\nExample: The initial pressure difference is 100 Pa, and it should be replaced when it reaches 200 Pa
\nThis standard is strictly followed in DOP supply air outlets, liquid tanks, and GMP workshops.
\nAn increase in pressure = accumulation of dust and blockage, decreased air volume, and deteriorated cleanliness
\n2. Insufficient leak detection (priority for DOP supply air outlets)
\nUse PAO\/DOP leak detection scanning:
\nFilter body leakage, frame sealing leakage, liquid tank sealing failure
\nInsufficient leak detection \u2192 Replace immediately, cannot continue to use
\n3. Exceeding cleanliness \/ dust particle standards
\nDaily inspection in the workshop:
\nSuspension particles, microorganisms exceed standards
\nAfter excluding problems with the fan, duct, and return air, it is the failure of the high-efficiency filter
\n4. Abnormal appearance and operating conditions
\nFilter material damage, blackening, mold growth, moisture absorption
\nSignificantly reduced air volume, weak air outflow from the outlet
\nExcessive dust in the workshop, failure of the pre-filter, and rapid contamination of the high-efficiency filter
\nIn such cases, replace immediately.
\n5. Time reference (bottom-line standard)
\nOrdinary clean rooms: 1-2 years
\nGMP pharmaceutical \/ operating room: It is recommended to replace every 1 year (mandatory)
\nFor workshops with large dust and frequent opening: 6-12 months<\/p>","protected":false},"excerpt":{"rendered":"
