I. Daily Inspection (Per Shift \/ Daily)
\nObserve the air outlet
\nCheck for uneven airflow, vibration, or abnormal noise
\nLook for discoloration, accumulated dust, or mold spots
\nCheck the pressure difference
\nRecord the current pressure difference of the high-efficiency filter
\nIf the pressure difference suddenly increases rapidly, it indicates that the front-end filter has failed or is clogged
\nProhibited Actions
\nIt is strictly forbidden to have dust, unpacking, sanding, or spraying large amounts of disinfectant under the high-efficiency air outlet
\nIt is strictly prohibited to poke, scrape, or collide with the uniforming plate of the air outlet
\nII. Weekly Maintenance
\nSurface Cleaning
\nUse a lint-free cloth and 75% alcohol to gently wipe the uniforming plate and frame
\nDo not use hard brushes, high-pressure air, or strong acids and alkalis Check the seal.
\nCheck if the filter strips and rubber seals are loose, cracked or have peeled off.
\nTighten loose screws (uniformly and evenly in opposite directions).
\nArchive the pressure difference records.
\nForm fixed records to facilitate the judgment of the blockage trend.
\nIII. Monthly Maintenance
\nPressure difference analysis
\nCompare with the initial pressure difference
\nIf it rises by more than 50%, it requires special attention
\nCheck the surrounding of the static pressure box
\nFor any condensation water, moisture, or mold
\nIf there is water, it must be dealt with promptly to avoid corrosion and bacterial growth
\nCheck the operation status of the fan\/FFU
\nFor any abnormal noise, vibration, or overheating
\nIV. Quarterly Maintenance
\nCheck the uniformity of wind speed
\nTest the wind speed at multiple points to ensure laminar flow stability
\nVisual leak detection
\nObserve if there is any air leakage or dust accumulation lines at the frame
\nCheck the front filter
\nCheck if the primary and intermediate filters are clogged and replace them in time to protect the high-efficiency ones
\nV. Annual Mandatory Maintenance (Critical)
\nPAO integrity leak detection
\nAll frames and filter materials should be thoroughly inspected for leaks. Those that do not meet the standards must be replaced
\nComprehensive performance verification
\nRecheck wind speed\uff0c pressure difference\uff0c and cleanliness
\nReplace the high-efficiency filter based on the situation
\nNormal environment\uff1a Replace every 1-2 years
\nHigh dust\uff0c high humidity\uff0c frequent sterilization\uff1a Replace every 1 year or so
\nReplace if the resistance reaches twice the initial resistance
\nVI. Maintenance Red Lines (Absolutely Not Allowed)
\nDo not use high-pressure air to directly blow the high-efficiency filter
\nDo not use water for rinsing
\nDo not randomly disassemble\uff0c step on\uff0c or squeeze
\nDo not use it for long-term use beyond the expiration date to avoid fiber detachment and dust loss
\nDo not not keep records and have the maintenance ledger checked by auditing
\nVII. Summary in One Sentence
\nRegularly check the pressure difference\uff0c wipe the surface weekly\uff0c inspect the status monthly\uff0c and replace it when due.<\/p>","protected":false},"excerpt":{"rendered":"
