Conclusion: You can replace it yourself, but there are certain conditions – it’s not just a simple replacement. It must meet the requirements of compliance, sealing, leak detection, and verification. Otherwise, the replacement would be in vain and could even affect the cleanliness level.
\n1. When can you replace it yourself?
\nIf the following conditions are met, you can replace it yourself:
\nYou have personnel who understand equipment maintenance (electricians \/ equipment technicians are sufficient)
\nYou have filters of the same specification, size, and qualified (with certificates and test reports)
\nAfter replacement, simple verification of air velocity, leak detection, and cleanliness can be done
\nThe workshop \/ laboratory does not involve GMP, pharmaceutical, etc. high-level certification (or it is internally allowed to replace by yourself)
\n2. Key steps for self-replacement (simplified version)
\nTurn off the power, unplug the power supply
\nRemove the decorative cover, trim, and old high-efficiency filter
\nClean the box, sealing groove, and replace the sealing rubber strip (aging requires replacement)
\nThe new high-efficiency filter should have the arrow pointing towards the outlet direction and be evenly pressed
\nLoosen the screws diagonally and tighten them to ensure no air leakage
\nTurn on the machine to measure air velocity, and if normal, then perform PAO \/ dust particle leak detection
\nRecord: replacement date, model, person, test results
\nKey point: Sealing is the soul. Air leakage = waste of effort, directly fails the inspection.
\n3. These situations are not recommended for self-replacement, please contact the manufacturer \/ professional personnel
\nPharmaceutical, biological, GMP, sterile laboratories
\nRequire third-party testing, auditing, factory inspection
\nComplex structure, sealed with liquid tank, DOP\/PAO leak detection interface
\nYou are unsure about the size, air volume, installation direction
\nYou do not have a leak detection instrument and cannot confirm if it is qualified
\n4. Summary in one sentence
\nFor ordinary laboratories \/ small workshops: You can replace it yourself, saving money and time
\nFor those with certifications \/ high requirements: Do not replace it yourself, avoid audit risks<\/p>","protected":false},"excerpt":{"rendered":"
