Constant-flow air supply ceiling – Core component replacement cycle
\n1. High-efficiency filters HEPA\/ULPA (the most critical consumable)
\nClassical cleanroom \/ operating room: 1-2 years
\nHigh usage frequency, large amount of dust: 6-12 months
\nJudgment criteria:
\nResistance reaches twice the initial resistance or cleanliness does not meet standards \u2192 must be replaced
\n2. Diffusing membranes \/ diffusers \/ damping nets
\nPTFE diffusing membranes: 2-3 years
\nAluminum alloy diffusers: 3-5 years
\nIf deformed, clogged, or the effect significantly decreases after cleaning, replace
\n3. Fans, motors
\nOrdinary centrifugal fans: 5-8 years
\nDC brushless fans: 8-10 years
\nIf noise increases, air volume significantly decreases, or abnormal heating \u2192 replacement
\n4. Sealing parts, liquid tank sealant
\nSealing strips: 1-2 years
\nLiquid tank sealant: 3-5 years
\nIf aging, cracking, or air leakage occurs \u2192 replace immediately
\n5. Pressure boxes, frames, shells
\nThese belong to structural components and do not need to be replaced regularly
\nNormal use can last 10-15 years with the ceiling
\nOne-sentence summary (for your convenience)
\nFilters: must be replaced within 1 year
\nDiffusing membranes: 2-3 years
\nFans: 5-8 years
\nSealing parts: 1-2 years<\/p>","protected":false},"excerpt":{"rendered":"
