Custom Size Pocket Bag Filter for Central AC with High Dust Capacity
Medium-Efficiency Pocket Air Filter
Medium-efficiency pocket air filters are critical filtration components in central air conditioning systems and cleanrooms. Their core structure includes an aluminum alloy or galvanized steel frame, zinc-plated pressure bars, and non-woven/fiberglass filter pockets . Pocket colors indicate efficiency grades: F5 (Orange), F6 (Green), F7 (Pink), F8 (Yellow) . Operating on principles of interception, inertial impaction, diffusion, and electrostatic adsorption, they capture 1-5μm particles with 60%-95% filtration efficiency
Core Features
-
Performance Advantages
- High Dust Holding Capacity: Extends service life and reduces replacement frequency
- Low Air Resistance Design: Lowers fan energy consumption for enhanced operational efficiency
- Robust Construction: Aluminum alloy frame resists deformation and withstands high air pressure impacts
-
Primary Applications
- Intermediate filtration in central AC systems (protecting HEPA filters)
- Purification systems for pharmaceutical workshops, electronics factories, and hospital operating rooms
- Commercial buildings (offices, shopping malls) for fresh air treatment
-
Usage & Maintenance
- Installation Requirement: Pocket openings must face vertically downward to ensure uniform airflow distribution
- Replacement Cycle: Replace every 3-4 months or when resistance reaches 400Pa
- Precaution: Requires pre-filtration with primary filters to prevent clogging by large particles
Industry Comparison
Compared to ultra-micro electrostatic filters, pocket filters offer lower initial costs and superior dust holding capacity. However, electrostatic models provide advantages in sterilization and submicron particle (0.3-1μm) filtration
