High-efficiency filters correctly installed + Complete maintenance plan (core points for extending service life)
\nI. Standard Installation (Installation errors will directly shorten half of the service life and cause dust leakage)
\n1. Pre-installation Preparation
\nClean the cleanroom ducts, static pressure boxes, and DOP supply air boxes thoroughly, removing any welding slag, dust, or debris; Installation of high-efficiency filters is not allowed without cleaning.
\nPre-install the first-stage G4 + second-stage F8\/F9 pre-filters in advance. Pre-filters are the first line of defense for high-efficiency filters; their absence will quickly block the high-efficiency filters.
\nOpen the box to inspect the filter: the filter material is undamaged, the aluminum frame is not deformed, and the liquid tank sealant is not cracked; if damp or damaged, it must be scrapped and cannot be used.
\nWhen transporting, do not grasp the filter material, only hold the frame edge to avoid scratching the glass fiber filter paper.
\n2. Installation Key Points for DOP Liquid Tank High-Efficiency Supply Air Outlet
\nPour the sealing gel into the liquid tank, ensure the liquid level is within the standard range. Place the filter vertically and steadily, with the entire ring of the frame completely submerged in the gel, without any suspended gaps.
\nInstall the diffuser plate last. During the installation process, avoid hitting the filter surface.
\nAfter installation, conduct a 24-hour no-load air supply to clean, then perform PAO\/DOP leak detection. The leak detection must be qualified before the high-efficiency filters can be put into production.
\nCalibrate the pressure differential gauge in advance and record the initial resistance under the rated air volume as the basis for later replacement.
\n3. FFU \/ High-Efficiency Installation Key Points with Partition
\nThe sealing strip is complete without any fractures, evenly pressed, with consistent force on all four sides, and no gaps on any single side.
\nDo not forcefully squeeze the filter material, align the frame, and do not tilt.
\n4. General Installation Prohibitions
\nDo not open the high-efficiency filter in a dusty or unclean environment;
\nDo not step on or press the filter paper;
\nAfter installation, must perform leak detection; leakage will contaminate the clean area and accelerate filter blockage.
\nII. Daily Operation and Maintenance Management (Core for extending service life)
\n(1) Grade-by-Grade Replacement of Pre-Filters (Most Critical)
\nFirst-stage G4 filter: Replace once when the pressure difference doubles or every 3-6 months to block large particles of dust;
\nSecond-stage F8\/F9 filter: Replace when the pressure difference doubles or every 6-12 months to intercept fine dust;
\nIf the pre-filter fails, the dust will directly impact the high-efficiency filter, reducing its service life by half or even to 3-6 months.
\n(2) Regular Pressure Differential Monitoring and Recording
\nDaily inspection of the pressure differential gauge and recording of the values;
\nSlow increase in resistance is normal dust accumulation;
\nSudden increase in resistance: Check if the pre-filter is damaged, if the dust production in the workshop has increased sharply, or if the doors and windows are frequently opened;
\nReplace immediately when the resistance reaches twice the initial resistance.
\n(3) Control of Cleanroom Environment
\nMaintain positive pressure in the workshop to prevent outdoor dust from flowing in;
\nWear complete dust-free clothing to reduce human skin debris and hair dust production;
\nDust in production materials should be pre-cleaned before entering the clean area;
\nReduce frequent opening of doors and large-scale personnel entry and exit to reduce the introduction of external dust.
\n(4) Maintenance of Air Conditioning Units and Air System
\nEnsure the air conditioning fan operates stably, avoid frequent start-stop, and avoid large air volume impact on the filters;
\nRegularly clean the new air ducts to reduce the load on the high-efficiency filters with high dust content;
\nTemperature and humidity control: Maintain humidity between 40% and 60%; High humidity can cause the filter to mold and the resistance to increase rapidly; Select moisture-proof high-efficiency filters in humid environments.
\nIII. Regular Special Maintenance Procedures
\nMonthly: Inspect the pressure differential, the appearance of the air outlet, and the accumulation of dust on the diffuser plate, wipe the outer surface of the air outlet;
\nQuarterly: Check the pressure difference of the first-stage and second-stage filters, replace the blocked pre-filters in time;
\nHalf-year\/Yearly: Perform PAO leak detection on DOP supply air outlets; Check if the sealing gel of the liquid tank is aging or cracking;
\nDuring production shutdown and maintenance: Blow clean the interior of the static pressure box, clean the accumulated dust in the air ducts, to avoid secondary dust pollution of the new high-efficiency filters.
\nIV. Prohibited Operations (Significantly Shorten Service Life)
\nDo not use water or high-pressure air to rinse the high-efficiency filter; If the glass fiber filter paper is damaged by water or fibers fall off, it must be scrapped immediately;
\nDo not tap or blow the high-efficiency filter surface to clean, which will damage the filter paper seal and cause leakage;
\nUse damaged, leak-tested, or damp filters;
\nLong-term shutdown without dust protection, with exposed air outlets covered with dust membranes; it is recommended to cover with dust membranes for long-term shutdown.
\nV. Dust Protection During Shutdown
\nLong-term shutdown of the workshop (more than 7 days):
\nTurn off the air conditioning supply;
\nFully seal the outside of the high-efficiency air outlet with a dust membrane;
\nBefore resuming production, remove the dust membrane first, run the air supply without load for half a day, retest the pressure difference and particle count, and then resume production.
\nVI. Summary of Core Logic
\nThe lifespan of the high-efficiency filter is 80% determined by the maintenance of the front-end pre-filter, and 20% by the installation sealing and dust control in the workshop; if the installation is airtight, replacing the primary \/ intermediate efficiency filters on time, and monitoring the pressure difference stably, the lifespan of the high-efficiency filter can be increased from 6 months to 2-3 years.<\/p>","protected":false},"excerpt":{"rendered":"
