V-Bank HEPA Filter is a high-performance air purification device that optimizes airflow distribution and filtration area through a V-shaped pleated structure. It complies with EN 1822 H13-H14 or ISO 16890 ePM1 99.95%-99.995% standards and is designed for industrial and medical scenarios with high air volume and high cleanliness requirements. With ultra-low resistance, high dust holding capacity and long life as its core advantages, it can intercept ≥99.97% of 0.3μm particles (such as viruses, bacteria, radioactive aerosols, etc.), becoming the ultimate filtration barrier for clean rooms, biosafety laboratories and high-end manufacturing industries.
Core structure and technical features
V-shaped pleat design
Multi-piece V-shaped arrangement: 4-12 groups of independent filter elements are combined in a V-shaped arrangement at an acute angle (usually 60°-90°), and the effective filtration area is increased by 3-5 times compared with the flat HEPA, significantly reducing the pressure drop (initial pressure difference ≤200Pa).
Filter material selection:
Glass fiber filter paper: high temperature resistance (≤350℃), chemical corrosion resistance, suitable for sterilization or industrial high temperature scenes;
Electret polyester fiber: electrostatic adsorption enhances submicron particle capture (MPPS efficiency ≥99.99%), and the initial pressure difference is lower.
Aluminum partition: serrated aluminum foil supports pleats to prevent filter material collapse, and withstands wind speed ≤4.0m/s.
Sealing and frame
Heavy duty metal frame: galvanized steel or stainless steel (304/316L), corrosion-resistant and impact-resistant, suitable for large air volume systems (≤10,000m³/h);
Silicone-free sealing: polyurethane casting or laser welding edge sealing, leakage rate ≤0.005%, in line with ISO 14644-1 clean room standards.
