Here is a set of preventive measures for unstable pressure differential readings of the air shower transfer window that can be directly implemented on-site, are simple and easy to remember, and are suitable for training, posting on the wall, and creating an SOP:
\nUnstable pressure differential readings of the pressure differential meter
\nPrevention measures
\n1. Daily operation prevention (most critical and effective)
\nDo not open both doors simultaneously
\nAlways ensure the electronic interlock is normal, prevent direct connection between the clean area and the non-clean area, and avoid chaotic airflow and sudden pressure differences.
\nClose the door tightly
\nAfter each use, confirm that the door body is completely closed, and the sealing strip is seamlessly attached without any gaps.
\nDo not block the nozzle or the air duct with items
\nPlace the transfer materials centrally, do not block the air shower nozzle or the return air filter, to ensure stable airflow.
\nDo not open the door or disturb during the air shower operation
\nDo not touch the door or move items during the air shower, to avoid sudden changes in pressure.
\n2. Daily maintenance prevention of pressure differential meter and pressure guiding tube
\nCalibrate the zero position once a month
\nThe pointer must return to zero when the power is cut off and the machine stops to prevent drift and random reading jumps.
\nDo not bend, press, or block the pressure guiding tube
\nRegularly inspect the pipeline, straighten the bends, and blow clean air once a month to prevent dust or water from blocking.
\nRegularly tighten the joints
\nPrevent loose air leakage and cause unstable readings.
\nDo not randomly disassemble, collide, or damage the pressure differential meter
\nAvoid damaging the internal mechanism.
\n3. Prevention of filtration system (stabilize the airflow from the source)
\nClean \/ inspect the primary filter weekly
\nBlockage of the primary filter \u2192 unstable air volume \u2192 pressure differential must jump.
\nRegularly check the sealing of the high-efficiency filter
\nPrevent air leakage and sudden changes in resistance.
\nReplace the high-efficiency filter promptly when reaching the pressure differential threshold
\nDo not use beyond the expiration date to avoid long-term overloading of the fan and fluctuation of air volume.
\n4. Prevention of door body and seal
\nRegularly inspect the door seal
\nReplace immediately if aging, deformed, or hardening to ensure consistent sealing.
\nRegularly tighten the hinges and locks
\nPrevent the door from not closing tightly and leaking air.
\nRegularly test the interlock function
\nEnsure that when one side of the door is opened, the other side is absolutely locked.
\n5. Prevention of fan and electrical components
\nListen for sounds, observe vibration
\nAddress any abnormal sounds or large vibrations promptly to avoid sudden changes in air volume.
\nEnsure stable power supply
\nUnstable voltage will directly cause pressure differential fluctuations.
\n6. Management prevention (the simplest but most easily overlooked)
\nEstablish a pressure differential record sheet
\nRecord daily, detect abnormalities early, and handle them promptly.
\nUniformly train the operators
\nClarify: standard actions for opening the door, placing items, air shower, and closing the door.
\nDo not allow non-professionals to randomly disassemble, adjust, or modify
\nDo not privately change parameters or dismantle the air duct.<\/p>","protected":false},"excerpt":{"rendered":"
