The daily cleaning of the DOP laminar flow transfer window should be carried out in separate areas and for individual components. It is necessary to ensure that the cleanliness meets the usage requirements while avoiding damage to the equipment components during the cleaning process.

II. Cleaning Methods for Components
\n1. Inner walls, transfer platform, observation window
\nCleaning tools: Dust-free cloth, clean cotton swabs (for corners and crevices)
\nCleaning agents: Neutral cleaner (pH 6-8), pure water (resistivity \u2265 18 M\u03a9\u00b7cm) Operation steps
\nDip a lint-free cloth in the diluted neutral cleaner (cleaner: pure water = 1:10), and wipe the inner walls and the transfer table in the same direction to avoid secondary contamination from repeated wiping.
\nUse clean cotton swabs to clean the corners, edges, and blind spots such as the frame and guide rails, and remove any remaining stains.
\nDip another lint-free cloth in pure water, wipe off the remaining cleaner.
\nUse a dry lint-free cloth to dry the water stains on the surface, or turn on the transfer window fan and run it for 5-10 minutes to dry. Notes for Attention
\nDo not use chlorine-based, acidic or alkaline cleaners as they may corrode the stainless steel surface.
\nWhen cleaning the observation window, avoid using hard tools to prevent scratching the glass.
\n2. Sealing Strip
\nCleaning Tools: Soft dust-free cloth, silicone-specific cleaner Operation steps
\nGently wipe the surface of the sealing strip with a lint-free cloth to remove dust and debris.
\nIf there is stubborn oil residue, apply a small amount of the special cleaning agent for silicone to wipe it off, and then clean it with pure water.
\nAfter cleaning, check if the sealing strip has any deformation or cracks. If necessary, apply a small amount of silicone grease for maintenance (once a quarter). Notes for Attention
\nDo not use organic solvents such as alcohol and acetone to prevent the sealing strips from aging and hardening.
\n3. Primary Filter
\nCleaning Tools: Soft-bristled brush, vacuum cleaner (with HEPA filter), cleaning sink
\nCleaning Method
\nRemovable Metal Mesh Filter
\nTurn off the power of the transfer window, then remove the filter.
\nGently brush off the surface dust with a soft-bristled brush, or use the vacuum cleaner with low power to suck up the dust.
\nIf there is a lot of oil stains, soak it in a neutral cleaner for 10-15 minutes, rinse with clean water, and dry it in a cool place (strictly prohibit direct exposure to sunlight or high-temperature drying).
\nNon-woven Fabric Filter
\nThe non-woven fabric material cannot be washed, directly use the vacuum cleaner to remove the floating dust on the surface.
\nAfter cleaning 3-5 times or after using for 3 months, replace the new filter directly. Notes for Attention
\nAfter cleaning, the filter needs to be confirmed to be completely dry before installation to prevent the growth of microorganisms due to moisture.
\nWhen installing, ensure that the filter fits tightly with the frame and there are no air leakage gaps.
\n4. The outer surface of the high-efficiency filter
\nCleaning tool: Anti-static dust-free cloth Operation steps
\nTurn off the power supply, gently wipe the dust on the filter surface with an anti-static dust-free cloth. Be gentle to avoid damaging the filter material.
\nDo not wash, blow with air, or disassemble the high-efficiency filter with water. If there are obvious stains on the surface or the pressure difference exceeds the standard, replace it directly.
\n5. Pressure gauge, control panel, door handle
\nCleaning tools: slightly damp dust-free cloth (tightly wrung out so that it does not drip water) Operation steps
\nUse a slightly damp and dust-free cloth to gently wipe the dial of the differential pressure gauge, the control panel buttons, and the door handle, removing fingerprints and dust.
\nAvoid allowing water to seep into the gaps of the control panel to prevent short-circuit faults.
\nAfter cleaning the differential pressure gauge, check if the readings are normal to ensure the accuracy of the instrument.
\nIII. Cleaning Prohibitions and Precautions
\nBefore cleaning, the power supply of the transfer window must be turned off. The ultraviolet lamp should be turned off and cooled for 10 minutes in advance to avoid ultraviolet radiation and burns from high temperatures.
\nAll cleaning tools must be dedicated and cannot be mixed with ordinary cleaning tools to prevent cross-contamination.
\nAfter cleaning, turn on the fan to run for 10-15 minutes to remove the residual cleaning agent odor, and then proceed with the transfer of items.
\nEstablish a cleaning record ledger to document the cleaning time, personnel, area and cleaning effect, facilitating traceability.<\/p>","protected":false},"excerpt":{"rendered":"
