Daily Maintenance Specifications for High-Efficiency Filters of Layered Air Filtration Hood
\nIt includes daily inspection, weekly check, monthly maintenance, annual verification, and replacement management. Throughout the process, the high-efficiency filter material is not touched or cleaned. The core is to protect the pre-filtering and monitor the pressure difference.
\n1. Daily Routine Inspection (Operator \/ Cleanroom Personnel)
\nPressure difference record (core)
\nCheck the pressure difference value on the high-efficiency pressure difference meter and compare it with the initial pressure difference ledger;
\nReport promptly if the pressure difference increases rapidly or the wind pressure fluctuates frequently.
\nAir flow appearance inspection
\nEquipment operating status the airflow is uniform without local lack of air or turbulence.
\nEquipment operation status
\nThe fan has no abnormal noise or severe vibration\uff1b the outlet is not blocked by materials\uff0c boxes\uff0c or tools.
\nEnvironmental control
\nClean the floor before transporting materials and turn off the layer flow hood\uff1b wait for the dust to disperse for 30 minutes before starting\uff1b do not direct the disinfectant mist onto the filter surface.
\n2. Weekly Maintenance (Maintenance Personnel)
\nCheck the dust accumulation on the surface of the primary filter and use an air gun for low-pressure blowing (only for the primary filter\uff0c prohibited for the high-efficiency filter).
\nCheck the sealing edges and rubber strips around the filter\uff1a are there any whitening\uff0c cracking\uff0c detachment\uff0c or air leakage gaps?
\nWipe the outer shell of the layer flow hood to keep it clean\uff0c avoiding dust accumulation in the intake section.
\nCheck if the return air outlet is blocked by debris to ensure normal circulation air volume and reduce high-efficiency resistance.
\n3. Monthly Deep Inspection
\nCompare the initial and intermediate pressure differences to determine if they have reached the replacement warning value\uff1b replace the pre-filter material in advance to protect the high-efficiency filter.
\nCheck the fan operating current and wind speed. If the wind speed is continuously lower than 0.36m\/s\uff0c eliminate the fan fault and determine that the high-efficiency filter is clogged. Check if there is any debris blocking the return air outlet to ensure normal circulation air volume and reduce high-efficiency resistance.
\n4. Annual Compliance Maintenance and Verification (GMP Mandatory)
\nPAO\/DOP High-Efficiency Integrity Leak Detection
\nScan the filter surface\uff0c frame\uff0c and sealing gasket at least once a year. If there is a leakage that cannot be repaired\uff0c immediately replace it.
\nCompletely test the average wind speed at the work surface and record it for archiving.
\nRecheck the initial pressure difference of the high-efficiency filter and update the ledger to evaluate the remaining service life.
\nOverall check the pressure strips\uff0c fastening screws\uff0c and evenly reinforce them diagonally to prevent long-term vibration from causing sealing gaps.
\nSimultaneously replace the aged sealing rubber strips to prevent dust bypass leakage.
\n5. Long-Term Shutdown Maintenance
\nIf the production is stopped for more than 3 days\uff1a cover the outlet with a dust-proof plastic film to isolate environmental floating dust.
\nIf the production is stopped for more than 1 month\uff1a start the machine for 1 hour each week to disperse internal moisture and avoid filter material mold and sealant aging.
\nBefore resuming production\uff0c remove the protection film\uff0c blow for 30 minutes with no load\uff0c recheck the pressure difference and wind speed\uff0c and then put it back into use.
\n6. Key Maintenance Prohibitions (Strict Prohibition of Operations)
\nDo not blow or wash the high-efficiency filter\uff1b it will puncture the glass fiber filter material and cause permanent leakage\uff1b
\nDo not touch the filter paper surface with your hands\uff1b grease on your hands will block the micropores and accelerate the increase in pressure difference\uff1b
\nDo not remove the high-efficiency pressure strips or modify the sealing structure privately\uff1b
\nDo not operate at full load with high wind speed for a long time to accelerate dust accumulation\uff1b
\nDo not wait for the high-efficiency pressure difference to double before arranging for purchase\uff1b prepare in advance to avoid production risks.
\n7. Replacement Determination and Maintenance Connection
\nIf the pressure difference reaches twice the initial value, the leak detection fails, or the wind speed remains persistently low, immediately arrange for replacement.
\nRemove the old high-efficiency sealing package from the cleanroom area\uff0c install the new high-efficiency filter\uff0c and must recheck the leak\uff0c measure the wind speed\uff0c and establish a new pressure difference ledger\uff1b
\nAfter each replacement of the high-efficiency filter\uff0c simultaneously check and replace the primary and intermediate pre-filters to maximize the service life of the new high-efficiency filter.
\nSimple Operation Summary
\nRecord the pressure difference daily\uff0c clean the primary filter weekly\uff1b
\nCheck the sealing monthly\uff0c and conduct leak detection annually\uff1b
\nDo not blow or wash the high-efficiency filter\uff1b the pre-filtering is frequently replaced to prolong the service life.<\/p>","protected":false},"excerpt":{"rendered":"
