Mini-Pleated HEPA Filter with 69/78/150/220 Thickness 1175x575x69mm Size and ≥ 99.97% Filtration Efficiency

High efficiency air filter with efficiency class H13-U15 engineered to meet stringent air purity requirements in laboratories and cleanroom environments.

The Mini-Pleated H13 V BANK HEPA Filter is designed for advanced air filtration applications in Air Handling Units (AHU), HEPA Filter Boxes, Fan Filter Units, and Cleanroom Terminal Filtration systems, ensuring superior air purity and performance.

V-shaped HEPA filters are essential in semiconductor front-end cleanrooms where nanometer-scale device features demand ultra-clean environments. In photolithography bays, even sub-0.1 μm particles can cause catastrophic defects on wafers.

The V-shaped design provides larger filtration surface area within compact frames (e.g., 570×570×69 mm), enabling ULPA U15/U17-grade efficiency (≥99.999995% @ 0.12 μm MPPS) while maintaining low initial resistance (~180 Pa at 0.45 m/s). This reduces energy consumption in recirculating fan filter units (FFUs) that operate continuously across large cleanroom footprints (>10,000 m²). The self-supporting pleated structure eliminates internal partitions, minimizing dead zones and airflow turbulence—critical for ISO Class 1-3 environments.

For technical validations, refer to ISO 14644-3 leak testing protocols to ensure compliance with stringent cleanroom standards.
