CONCENTRATION TO INNOVATION FOR REVOLUTION

NanoFiltech focus on the R&D, manufacture and sales of high-class functional nanofiber materials. 

Product
Separator-Free High-Efficiency Filter Series

The NAFIL Series is a separator-free, high-efficiency air filter designed as the final filtration stage in critical environments. Installed downstream of pre-filters (e.g., MERV 8-13) or bag filters, it captures 99.99% of 0.3μm particles (tested per EN1822), ensuring ISO Class 5-8 cleanroom compliance.

Featuring ultra-thin frames (50-110mm) with anodized aluminum construction and nanofiber/PTFE media, it outperforms traditional HEPA filters by eliminating separator blocks—reducing pressure drop, energy costs, and maintenance frequency. Ideal for laminar airflow systems in pharmaceuticals, semiconductor fabs, and biotech labs.

Compatible with FFUs, AHUs, and modular cleanrooms, the NAFIL Series extends system lifespan when paired with proper upstream filtration.
