CONCENTRATION TO INNOVATION FOR REVOLUTION
NanoFiltech focus on the R&D, manufacture and sales of high-class functional nanofiber materials.

Box Air Filter is designed as a pre-filter before HEPA/ULPA stages. It’s suitable for central HVAC systems, AHUs, and industrial air compressors. With rigid construction and stable airflow, it can replace bag filters in certain conditions while ensuring high dust-holding capacity and low resistance.
Product Features:
~V-Type Low Pressure Drop Filter
~Separator-Free Design, Nanofiber Filter Paper
~High Dust Holding Capacity, Long Service Life
~Robust Structure, Ensures Performance Under Turbulent Flow Conditions
Product Structure:
~V-Shaped Pleat Design- Maximizes filtration area, reduces pressure drop, and extends service life.
~High-Efficiency Filter Media- Made from ultra-fine fiberglass or nanofiber materials, offering ≥99.97% efficiency @ 0.3μm.
~Robust Frame Construction- Durable housing made of plastic, galvanized steel, or aluminum — corrosion-resistant and deformation-free.
~Airtight Sealing- Equipped with PU or EPDM gaskets to prevent air leakage and maintain cleanroom integrity.
~Anti-Deformation Support Structure- Built-in support grid or spacers to maintain pleat shape and ensure uniform airflow distribution.
