Compact & Sustainable: How V-Bank Filters Redefine High-Efficiency Filtration for HVAC Systems｜Nanofiltech NAFIL-V Series
In cleanrooms, pharmaceutical facilities, hospitals, and advanced HVAC systems, filtration solutions are never simply about “the highest efficiency possible.” The real challenge lies in achieving the optimal balance of efficiency, pressure drop, and service life within limited space.
The Nanofiltech NAFIL-V Series integrates a compact V-Bank structure + nanofiber filter media + separatorless hot-melt design to deliver system-level performance across efficiency classes E10/E11/E12/H13—ensuring low pressure drop, long service lif
e, and structural stability.
Why NAFIL-V (V-Bank)?
Low Pressure Drop / High Airflow / Low Energy Use:The V-Bank design significantly increases effective filter area, maintaining high airflow within the same footprint while reducing pressure drop—directly lowering fan energy consumption.
Nanofiber Filter Media:Fine fibers with uniform pore distribution ensure consistent particle capture. Across E10–H13 classes, filters provide both high efficiency and low initial resistance.
High Dust-Holding Capacity & Long Service Life:Enhanced dust capacity delays the “final resistance point,” minimizing maintenance frequency and downtime risks.
Structural Stability & Turbulence Resistance:Separatorless hot-melt design resists flow deviation; multiple frame options (plastic, galvanized steel, aluminum) adapt to different conditions.
Disposal-Friendly:Optional single-flange polypropylene (PP) frame supports easier incineration disposal in certain regions—simplifying end-of-life handling (disposal depends on local regulations and costs).
Typical Applications
l Cleanroom Terminal / Supply & Return Air Sections (Pharma, Electronics, Healthcare): Stable efficiency and airflow under VAV and turbulent conditions.
l Space-Limited AHUs/MAUs: Compact 292 mm depth modules help achieve compliance in “tight-space, high-airflow” projects.
l Commercial & Industrial HVAC Upgrades: Deployed as final-stage or upstream pre-high-efficiency filters, balancing energy performance and reliability while reducing HEPA load and extending HEPA service life.

Selection Guide (for engineers)
Airflow Density / Face Velocity: At a given face velocity, V-count (2V/4V/5V) impacts effective filter area and resistance. At the same airflow, a higher V-count yields lower resistance and longer service life.
Efficiency Options:
l E10/E11: As upstream pre-high-efficiency filters, reducing load and resistance on downstream HEPA filters.
l E12/H13: For terminal stages or retrofit projects with stricter cleanroom requirements, where V-Bank design maximizes overall efficiency/pressure drop/service life balance.
Final Resistance Management: Recommended control at 450 Pa with ΔP monitoring and routine checks to prevent excessive resistance, energy waste, or bypass risks.
Summary
For projects with space constraints, energy sensitivity, and strict cleanliness requirements, the Nanofiltech NAFIL-V Series provides a balanced optimization of efficiency, energy use, and service life—covering efficiency grades E10–H13, with low initial resistance (80–240 Pa), a reasonable final resistance (450 Pa), compact 292 mm depth, and multiple frame materials.
Whether you are upgrading VAV cleanroom systems, enhancing terminal efficiency, or boosting airflow in limited AHU space, the NAFIL-V is ready for on-site testing.
