Here is a set of general, standardized, and directly applicable installation steps for ultra-clean workbench high-efficiency filters, suitable for both horizontal flow and vertical duct systems, applicable to pharmaceutical factories and laboratories.
\nInstallation Steps for Ultra-Clean Workbench High-Efficiency Filters
\nI. Preparation
\nTurn off the power of the ultra-clean workbench and unplug the plug.
\nPrepare the new high-efficiency filter: Check the size, rated air volume, efficiency grade (H13\/H14), and inspect for no damage or deformation.
\nPrepare tools: Phillips screwdriver, clean dust-free cloth, 75% ethanol, sealing rubber strips (if aging, consider replacing them together).
\nClean the operation area to reduce dust.
\nII. Disassembly of the Old High-Efficiency Filter
\nOpen the rear\/top access cover or outlet decoration cover of the ultra-clean workbench.
\nLoosen the fixing strips\/screws of the high-efficiency filter (it is recommended to loosen diagonally to avoid deformation).
\nGently remove the old high-efficiency filter, do not hit it hard to prevent secondary dust contamination.
\nWet the inside of the box, the air duct, the sealing groove, and the strips with 75% ethanol, and thoroughly clean.
\nIII. Installation of the New High-Efficiency Filter
\nConfirm the air flow direction: The arrow on the outer frame of the filter must point to the outflow side (the operation area), installing it in the opposite direction will result in low air volume and high resistance.
\nPlace the new high-efficiency filter smoothly into the sealing groove, ensure uniform contact on all four sides, without warping or edge curling.
\nInstall the strips, gradually tighten the screws diagonally, apply uniform force to avoid local over-tightening and resulting in deformation and air leakage.
\nCheck the sealing around the edges: Press the frame lightly with your hand, there should be no looseness or obvious gaps.
\nIV. Restoration and Trial Run
\nReplace the access cover and decoration cover.
\nConnect the power supply and turn on the fan. Run for 5-10 minutes.
\nObserve if the operation is normal: no abnormal noise, no obvious vibration, uniform air outflow.
\nV. Post-Installation Verification (Must be done)
\nAir velocity measurement
\nThe average air velocity in the operation area should be 0.3-0.6 m\/s, and it should be uniform at all points.
\nLeak detection
\nIn GMP scenarios, PAO\/DOP leak detection must be performed;
\nIn general laboratories, at least smoke leak detection should be conducted to confirm there is no leakage.
\nSimple confirmation of cleanliness: no obvious dust flying or falling.
\nVI. Record and Archiving
\nFill in the maintenance record, including:
\nReplacement date
\nFilter model and specification
\nInstaller
\nAir velocity, leak detection results
\nNext replacement date
\nKey precautions
\nDo not install the arrow in the opposite direction, as it is equivalent to a waste replacement.
\nSealing is the core, air leakage is more dangerous than dirty filter.
\nDo not squeeze the filter forcefully, as it will cause filter paper damage.
\nAfter replacement, leak detection must be conducted, and it cannot be just “installed and considered done”.
