V-Bank HEPA Filter is a high-efficiency air purification device that achieves ultra-large filtration area and ultra-high dust holding capacity through V-shaped pleated structure. It is designed for industrial and medical scenarios with high air volume and high cleanliness. It complies with EN 1822 H13-H14 or ISO 16890 ePM1 99.95%-99.995% standards, and can intercept ≥99.97% of 0.3μm particles (such as viruses, bacteria, radioactive particles, etc.), becoming the ultimate filtration barrier for clean rooms, biosafety laboratories, electronic manufacturing and energy industries.
Core structure and technical highlights
V-shaped pleated design
Multi-piece V-shaped layout: 4-12 groups of independent filter elements are arranged at an acute angle of 60°-90°, and the effective filtration area is increased by 3-5 times compared with flat HEPA, significantly reducing airflow resistance (initial pressure difference ≤180Pa).
Filter material selection:
Glass fiber: high temperature resistance (≤350℃), chemical corrosion resistance, suitable for pharmaceutical sterilization and industrial high temperature scenes;
Electret polyester fiber: electrostatic adsorption enhances the capture ability of 0.1μm particles (MPPS efficiency ≥99.99%), and the initial pressure difference is lower.
Aluminum partition: serrated corrugated aluminum foil supports the filter material to prevent fold collapse and withstand wind speed ≤4.0m/s.
Seal and frame
Heavy metal frame: 304/316L stainless steel or galvanized steel, corrosion-resistant and impact-resistant, suitable for large air volume systems (≤50,000m³/h);
Zero leakage seal: polyurethane casting or laser welding edge sealing, leakage rate ≤0.005%, in line with ISO 14644-1 clean room standards.
