\nPartitioned efficient filter: Built-in aluminum foil \/ paper partition to support the filter paper, with a large gap between the filter layer folds, overall thickness is thick (150\/220mm), and the filter material support strength is high<\/p>\n
DOP liquid channel efficient filter: No partition, hot melt adhesive strips, lightweight model (66\/93mm), the filter core is more compact, and the wind resistance is lower
\n2. Edge frame sealing\u00a0
\nPartitioned efficient filter: Flat edge frame, sealed by foam sealing strips; disassembly may cause frame leakage; DOP leak detection has blind areas
\nDOP liquid channel efficient filter: Four-sided U-shaped liquid channel, matched with blue jelly elastic glue for immersion sealing; seamless sealing, can conduct complete DOP scanning leak detection for the entire machine, in line with GMP audit requirements
\n3. Performance advantages and disadvantages comparison (short sentences with pictures used)
\nPartitioned efficient filter
\n\u2705 Advantages
\nPartitioned support, no deformation under high wind pressure, solid structure
\nLarge filter layer expansion area, high dust capacity, long replacement cycle
\nWide filter gap, convenient manual leak detection and repair
\nAluminum partition model suitable for large air volume continuous operation
\n\u274c Shortcomings
\nFlat sealing strips have average sealing performance, prone to side leakage in high-clean areas
\nThick thickness, occupying a lot of ceiling space
\nCannot conduct complete DOP integrity detection
\nDOP liquid channel efficient filter
\n\u2705 Advantages
\nJelly liquid channel sealing, nearly zero leakage, highest airtightness
\nLightweight, low resistance, lower fan energy consumption
\nSupports complete DOP\/PAO dust emission leak detection, a must-have for pharmaceutical and operating room compliance
\nKnife slot type installation, quick disassembly, no need for sealing strips
\n\u274c Shortcomings
\nNo partition structure, lower dust capacity and pressure resistance than partitioned type
\nHigher price, requires a dedicated liquid channel supply air outlet for use
\n4. Application scope distinction
\nPartitioned efficient filter applicable to
\nLarge purification air conditioning units, main supply air systems of workshops
\nWorkshops with high dust concentration, 24-hour continuous production
\nLarge air volume laminar flow equipment, end of ordinary clean rooms
\nWorkings without mandatory GMP audit requirements for sealing leak detection
\nDOP liquid channel efficient filter applicable to
\nGMP pharmaceutical sterile areas, filling \/ freeze-drying workshops
\nOperating rooms, ICU, P2\/P3 biosafety laboratories
\nHundred-level, ten-thousand-level ultra-high cleanliness workshops
\nClean rooms that require regular DOP integrity verification and strict control of leakage
\nFour words to summarize the selection: Pursue large air volume, long lifespan, high pressure resistance, choose partitioned efficient; Require zero leakage, GMP compliance, complete DOP leak detection, choose DOP liquid channel efficient.<\/p>","protected":false},"excerpt":{"rendered":"
