The core of daily maintenance for ultra-low resistance high-efficiency filtration units is pressure difference monitoring, regular inspections, standardized cleaning \/ replacement, and seal checks to ensure low resistance and high efficiency, extend lifespan, and avoid air leakage and secondary pollution.
\n1. Daily Monitoring (daily \/ per shift)
\nPressure difference monitoring: Record the pressure difference at the inlet and outlet, establish an initial baseline value; the final resistance is usually 1.5\u20132 times the initial value, and an alert is triggered when it reaches 80%.
\nAppearance and operation: Check for deformation, damage, and dust accumulation on the casing and frame; no blockage at the inlet and outlet; the fan \/ valve operates smoothly, without abnormal sounds, and no abnormal vibrations.
\nAir volume and cleanliness: Observe if the supply air volume is stable; whether the particle concentration in the clean room \/ workshop meets the standard.
\nRecord and archive: Daily record the pressure difference, operating status, and abnormal situations, forming an operation log.
\n2. Periodic Inspection and Maintenance (according to schedule)
\n1. Every week \/ every two weeks
\nClean the casing and floating dust on the inlet surface (using a soft brush \/ vacuum cleaner, gently sweep from the clean side to the contaminated side).
\nCheck the sealing strips and sealing grooves on the frame, for no aging, cracking, or detachment.
\nVerify the pressure difference trend to determine if it is approaching the warning value.
\n2. Every month
\nComprehensive inspection of filter materials: Check for any damage, bulging, discoloration, or mold; check if the frame is loose.
\nCheck if the fasteners and connecting parts are secure.
\nTest the alarm function (if any).
\n3. Every quarter \/ every half year
\nDeep cleaning: For washable types, clean according to the specifications (\u226440\u2103 warm water, neutral detergent, natural air drying \/ \u226460\u2103 low-temperature drying).
\nFor non-washable types: Only dry sweep \/ reverse dust removal, strictly prohibit water washing.
\nRecheck the sealing performance: Replace the sealing strips as necessary.
\nSystem linkage check: Match with the front-end primary efficiency and rear-end high-efficiency filters.
\n3. Cleaning and Regeneration Specifications (for washable types)
\nPower off and disconnect the power supply, remove the filter to prevent secondary pollution.
\nDry sweep: Lightly sweep with a soft brush or low-pressure compressed air (\u22640.3MPa) to remove large particles of dust.
\nWater wash: \u226440\u2103 warm water, rinse from the clean side to the contaminated side; optional neutral detergent soaking for 10\u201315 minutes.
\nRinse until the water is clear, air dry or \u226460\u2103 low-temperature dry, strictly prohibit exposure to the sun.
\nCheck: The filter material is undamaged, and the efficiency has no significant decrease before reuse; the number of cleanings \u22643 times, and if exceeded, replace.
\n4. Replacement Criteria and Operations
\n1. Replacement trigger conditions (satisfy any one of them)
\nPressure difference reaches 1.5\u20132 times the initial value (final resistance).
\nFilter material is damaged, moldy, or severely dusty and cannot be cleaned.
\nAir volume \/ cleanliness continues to not meet the standard, after excluding other causes.
\nFor washable types, clean \u22653 times or efficiency decreases >5%.
\n2. Replacement cycle reference (dynamic adjustment)
\nGeneral environment: 6\u201312 months.
\nHigh dust \/ high load (such as electronics, pharmaceuticals, subway hubs): 3\u20138 months.
\nLow-load environment: 12\u201324 months.
\n3. Replacement operation points
\nPower off and disconnect the power supply, take precautions to prevent dust at the site.
\nRemove the old filter gently, vacuum clean the frame and sealing grooves.
\nCheck the appearance, efficiency, and sealing integrity of the new filter, install it in the correct direction.
\nCompact the seal, no air leakage; measure the pressure difference, air volume, and check for leaks (if necessary, PAO\/DOP).
\nRecord the replacement time, model, initial pressure difference, and operating parameters.
\n5. Common Problems and Solutions
\nResistance rises too quickly: Failure of the front-end primary efficiency, high environmental dust, excessive air volume; strengthen front-end filtration, adjust air volume, shorten maintenance cycle.
\nLeakage \/ cleanliness decline: Aging sealing strips, frame deformation, improper installation; replace the sealing, correct the frame, reinstall and check for leaks.
\nFilter material moldy: High humidity, condensation water; control temperature and humidity, enhance ventilation, replace the moldy filter in time.
\nAbnormal vibration \/ noise: Fan failure, frame loosening, filter installation offset; Maintenance shutdown, tightening, repositioning.
\nVI. Safety and Management
\nDuring maintenance, power is cut off, signs are hung, and dedicated personnel are on duty. Safety belts are used for high-altitude work.
\nUsed filters are sealed and packaged, and disposed of in accordance with environmental protection requirements.
\nEstablish a full life cycle ledger: model, installation date, initial pressure difference, maintenance\/cleaning\/replacement records, operation data.
\nDevelop emergency plans: rapid response procedures for pressure surge, air leakage, equipment failure, etc.<\/p>","protected":false},"excerpt":{"rendered":"
