V- Bank HEPA filter, V-style air filter plastic enclosing frame
Core Structure & Material Composition
1. Outer Frame
- ABS plastic frame: Lightweight, anti-corrosion, low cost, ideal for general cleanroom AHU;
- Galvanized steel frame: High mechanical strength, shock-resistant, suitable for industrial ventilation;
- Aluminum alloy / SUS304 stainless steel frame: For high-humidity, disinfection and corrosive workshop environments.Single flange / no-flange designs are available for flexible installation inside filter racks.
2. Filter Media & Separator
- Filtration medium: Ultra-fine borosilicate glass fiber HEPA paper, uniform micro-pore structure to capture 0.3μm particles efficiently; optional synthetic fiber media for low-temperature, anti-static requirements;
- Separator: Hot-melt polypropylene glue mini-pleat partition, replaces metal aluminum separators, avoids particle shedding and corrosion, keeps consistent pleat spacing for even airflow distribution;
- Sealing: Two-component PU polyurethane glue fully seals media packs and frame to eliminate air bypass leakage.
3. V-Cell Combination Configurations
4. Sealing Gasket
Main Technical Grades & Performance
- Filtration efficiency standard: EN1822
- H10–H12: Medium-high efficiency, used as pre-filter to protect terminal HEPA boxes;
- H13 (≥99.99% @ MPPS), H14 (≥99.995% @ MPPS): HEPA grade, final filtration for ISO5–ISO8 cleanrooms;
- Optional U15–U19 ULPA grade for ultra-high purity semiconductor labs.
- Operating environment: Continuous temperature ≤80°C, relative humidity up to 100% non-condensing;
- Initial pressure drop: 100–180Pa, recommended final replacement resistance: 450–550Pa;
- Max airflow per standard unit: Up to 5000 m³/h.
Outstanding Product Advantages
-
Ultra-Large Filtration Area & High Airflow
Multi-V folded structure multiplies effective media area in the same frame size, supporting massive air volume circulation without increasing system wind resistance, greatly reducing fan energy consumption.
-
Low Pressure Drop & Energy Saving
Uniform mini-pleat layout minimizes airflow turbulence; lower static pressure loss cuts long-term HVAC operating cost vs standard single-panel HEPA filters.
-
Super Dust Holding Capacity & Long Service Life
More filter media stores more particulate contaminants, filter replacement cycle extends 2–3 times compared to ordinary box HEPA filters, lowering maintenance labor and material costs.
-
Excellent Anti-Leakage & Sanitary Performance
Full PU seamless sealing between media and frame, no air bypass; non-shedding fiberglass and plastic separators avoid secondary particle pollution, fully meeting pharmaceutical GMP and hospital infection control requirements.
-
Strong Turbulent Air Adaptability
Rigid integral frame and fixed hot-melt pleats resist airflow impact deformation, stable performance under variable air volume (VAV) AHU operating conditions.
-
Flexible Customization
Customizable outer dimensions, V-cell quantity, frame material, flange type, efficiency grade; activated carbon composite V-bank filter optional for simultaneous dust and odor removal.
