Based on the paper partition \/ aluminum partition you previously asked about, I have compiled a set of filter selection steps that can be directly implemented in the project. This selection process takes into account various factors such as working conditions, cleanliness level, environment, and cost, and is very practical in engineering.
\n1. First, determine these 4 core conditions:
\nCleanliness level requirements
\nFor general ventilation and comfort air conditioning: Medium efficiency is sufficient, and high efficiency is usually not necessary.
\nFor 100,000-level and 10,000-level clean rooms: Initial efficiency + medium efficiency + high efficiency is required.
\nFor 100-level, 1,000-level: High efficiency \/ ultra-high efficiency filters must be used.
\nTemperatura y humedad ambiental
\nNormal temperature and dryness: Paper partition can be used for high efficiency.
\nHigh temperature, high humidity, and steam sterilization: Aluminum partition must be used for high efficiency.
\nPresence of corrosive and chemical gases
\nFor ordinary air: Paper partition is feasible.
\nFor acids, bases, and organic solvents: Only aluminum partition + anti-corrosion frame can be selected.
\nVibration and installation conditions
\nCeiling, quiet units: Paper partition can be used.
\nNear the fan, high vibration: Aluminum partition should be preferred, as it is less prone to damage.
\n2. Select directly based on the usage scenario (the most practical)
\n1. Ordinary comfort air conditioning, office buildings, shopping malls
\nConfiguration: Initial efficiency G4 + medium efficiency F8
\nNo need for high-efficiency filters, low cost, easy maintenance
\n2. Ordinary clean workshops, electronic assembly, food packaging (dry and normal temperature)
\nConfiguration: Initial efficiency + medium efficiency + paper partition high efficiency
\nAdvantages: Low cost, large dust capacity, high cost performance
\n3. Pharmaceutical factories, operating rooms, sterile wards
\nConfiguration: Initial efficiency + medium efficiency + aluminum partition high efficiency \/ no partition high efficiency
\nKey: Resistance to moisture, high temperature sterilization, stable structure
\n4. High-temperature and high-humidity environments (boiling, sterilization, drying)
\nMust use: Aluminum partition high-efficiency filters
\nPaper partition is prohibited, as it will be damp and collapse
\n5. Semiconductor, precision electronics, high-cleanliness laboratories
\nSelection: No partition high-efficiency filters (PP partition)
\nLow resistance, thin volume, suitable for high-density installation
\n6. Chemicals, corrosive gases
\nSelection: Aluminum partition + stainless steel frame
\nFilter material selection should be resistant to chemicals
\n3. Principles for filter combination (very important)
\nMust have three-level protection
\nInitial efficiency protects medium efficiency \u2192 Medium efficiency protects high efficiency
\nLack of the previous stage of filtration will cause the high efficiency to quickly clog, resulting in extremely high costs
\nEfficiency gradually increases
\nInitial efficiency G3\/G4 \u2192 Medium efficiency F5-F8 \u2192 High efficiency H11-H14
\nThe efficiency of the previous stage is too low, causing excessive burden on the subsequent stage
\nThe final filter determines the air exchange rate and cleanliness
\n100-level: laminar flow + HEPA\/ULPA
\n10,000-level \/ 100,000-level: turbulent flow + high-efficiency filters
\n4. Paper partition vs aluminum partition final selection rule
\nDry and normal temperature, limited budget, ordinary clean area
\n\u2192 Select paper partition high efficiency
\nHigh-temperature and high-humidity, sterilization environment, high cleanliness level, high vibration
\n\u2192 Select aluminum partition high efficiency
\nUltra-thin air outlet, low resistance, clean operating room
\n\u2192 Select no partition high efficiency (PP partition)
\n5. Finally, consider the cost
\nInitial cost is low: paper partition
\nLong-term use cost is low: aluminum partition (longer lifespan, less replacement)
\nThe total cost is the lowest: ensure the previous stage of filtration to protect the high-efficiency filter<\/p>","protected":false},"excerpt":{"rendered":"
