The vessel frame high-efficiency filtration unit is mainly used for air filtration in clean rooms, laminar flow areas, and at the end of purification equipment. The core maintenance focuses on seal checks, pressure difference monitoring, cleaning protection, replacement cycle, and maintenance of the vessel frame structure, to ensure filtration efficiency and stable airflow. The following are the standardized maintenance steps:
\n1. Daily inspection (daily \/ weekly)
\nPressure difference monitoring
\nCheck the pressure difference gauge of the high-efficiency unit and record the initial resistance: Generally, the initial resistance of a high-efficiency unit is 180-220 Pa. When the pressure reaches twice the initial resistance or reaches the upper limit specified by the manufacturer, the filter element must be replaced. Visual inspection
\nObservation of the filter element for any damage, frame leakage, blackening, dust accumulation, moisture absorption, mold formation; Check the **frame (support framework)** for deformation, loosening, rusting, and weld seam cracking.
\nSealing inspection
\nCheck if the filter element and the frame, as well as the frame edge sealing strip, have fallen off, cracked, hardened, or have any air leakage gaps. Air leakage will directly damage the cleanliness level.
\nOperation status
\nCheck if the unit’s air outlet is uniform, if there are any abnormal noises or vibrations, and determine if the fan \/ air supply system is abnormal.
\nII. Regular Maintenance (Monthly \/ Quarterly)
\n1. Maintenance of the frame of the frame
\nMetal frame: Use a dust-free cloth to wipe the surface dust; Do not directly rinse with water; For slight rust, treat with a neutral rust remover and then apply anti-rust paint.
\nTighten all fixing bolts and clasps to prevent the frame from loosening and causing the filter element to shift or leak air.
\nDo not knock or press the frame forcefully; Avoid frame deformation caused by pressure to prevent the filter element seal from failing.
\nHigh-efficiency filter elements should not be washed with water or blown with air in reverse, as this will damage the fiberglass filter material and reduce the filtration efficiency.
\nHigh-efficiency filter elements cannot be washed with water or blown back to the air supply direction for reverse sweeping\uff0c as this will damage the fiberglass filter material and reduce the filtration efficiency.
\nOnly use a dust-free cloth to gently wipe the dust on the outer frame and the air outlet surface\uff1b Do not touch the air inlet surface.
\nIn humid areas\uff0c check if condensation occurs and promptly investigate temperature and humidity\uff1b Prevent the filter element from mold growth and resistance from rising.
\n3. Maintenance of the sealing system
\nReplace the aging\uff0c hardened\uff0c or fallen sealing strips with the same specification of anti-aging silicone rubber sealing strips in time.
\nEnsure uniform compression during installation\uff0c without local underpressure or gaps\uff1b If necessary\uff0c perform DOP leak detection.
\nIII. Replacement Standards (Key Points)
\nPressure difference reaches twice the initial resistance\uff1b
\nFilter element damage\uff0c air leakage\uff0c moisture absorption\uff0c mold formation\uff1b
\nThe microorganisms and dust particles in the clean area exceed the standard, and the leak detection is unqualified.
\nRegularly replace in conventional usage environments every 6 to 12 months\uff0c and in high dust \/ high humidity environments every 3 to 6 months.
\nReplacement operation points
\nShut down\uff0c depressurize\uff0c and take personnel protection measures in the clean area\uff1b
\nRemove the old filter element\uff0c clean the accumulated dust inside the frame\uff1b
\nNew filter elements should be handled gently\uff0c and the filter material surface must not be touched\uff1b
\nUniformly compress the seal\uff0c and perform integrity leak detection (DOP\/PAO leak detection) after installation\uff1b
\nRecord the replacement time\uff0c pressure difference\uff0c and leak detection results\uff0c and establish a ledger.
\nIV. Prohibited Operations and Precautions
\nDo not wash\uff0c brush\uff0c or reverse-sweep the high-efficiency filter element\uff1b
\nDo not drill holes\uff0c cut\uff0c or press the filter element surface\uff1b
\nThe frame must not be corroded by strong acids or strong alkalis\uff1b Take anti-corrosion measures in humid environments\uff1b
\nDisassembly and assembly must be carried out under clean conditions to avoid secondary pollution\uff1b
\nWaste filter elements should be disposed of in accordance with the hazardous waste\/purification consumables standards and must not be discarded at will.
\nV. Long-term Shutdown Maintenance
\nClean the surface dust before shutdown\uff1b
\nWrap the air outlet surface of the filter element with a dust-proof film to prevent dust accumulation\uff1b
\nMaintain a dry and ventilated environment to avoid the filter element from getting damp\uff1b
\nCheck the pressure difference\uff0c seal\uff0c and integrity before restarting\uff0c and use them before putting it back into use if they are qualified.<\/p>","protected":false},"excerpt":{"rendered":"
