V bank HEPA Filter

V Bank HEPA Filter, also named W-type large airflow compact HEPA filter, is a high-efficiency terminal filter specially designed for high-air-volume central air handling units (AHU) and cleanroom ventilation systems. Multiple mini-pleat filter packs are arranged in parallel V-shaped groups inside a rigid frame, which greatly expands the effective filtration surface within limited cabinet depth. Compared with traditional flat panel HEPA filters, it delivers larger airflow, lower operating resistance and longer service life, widely deployed as secondary or final high-efficiency filtration before laminar flow ceilings, air showers and HEPA terminal boxes.

Core Structure & Material Composition

1. Outer Frame

Multiple frame material options to match different working conditions:

• 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

Standard modular V group designs: 3V / 4V / 5V / 6V cells. More V packs mean larger filtration area, higher rated airflow and stronger dust holding capacity. Standard filter depth: 292mm, compatible with universal AHU filter slot sizes.

4. Sealing Gasket

EPDM / PU elastic foam gasket pre-installed on frame edge, ensures airtight fit with AHU cabinet to prevent unfiltered air leakage around filter edges.

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

1. 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.

2. 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.

3. 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.

4. 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.

5. 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.

6. 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.
