How to Clean High Efficiency Filters
How to Clean High Efficiency FiltersPurpose of high-efficiency filter cleaning: To establish high-efficiency filter outlet cleaning and replacement operation procedures to ensure that the clean room (area) air cleanliness meets the composite requirements or laminar flow rate to meet the regulations.How is the cleaning of a high-efficiency filter? 1. When the air velocity of the high-efficiency filter drops to the minimum value or the air volume is 70% of the original air volume, the initial and intermediate filters should be replaced, and regulate the air volume control valve of the static pressure box. 2. They must be replaced when the workshop is shut down and the air-conditioning purification unit stops running. 3. After replacing the high-efficiency filter, it can be put into use only after passing the leakage check. 4. Cleaning of high-efficiency filter deflector: Remove the screws of the high-efficiency filter deflector, remove the deflector, wipe the deflector to clean it, and put it back to its original position. 5. Maintenance of high-efficiency filter: When the detection of dust particles fails and it is confirmed that it is caused by the leakage of the high-efficiency filter, it should be operated by the "High-Efficiency Filter Leakage Picking Operation Procedures" to find out the leakage point. When the frame leaks, tighten the fastening screws. Sealant leakage points can be sealed by leakage on the filter surface. If the leakage point is too much to be repaired, it should be replaced. 6. Remove the deflector plate, loosen the fastening nut, remove the original high-efficiency filter, install the new high-efficiency filter, tighten the nut, and install the deflector plate. 7. Record: Fill in the cleaning and replacement record of the air conditioner filter. |
