G1 Nylon Mesh Prefilter
Washable G1 nylon mesh prefilter for HVAC fresh-air units, AHUs and cleanroom pre-filtration. High airflow, low resistance and reusable — resists acid, alkali, oil mist and high temperature.
Overview
The G1 nylon mesh prefilter is a washable coarse-dust filter designed for commercial and industrial heating, ventilation and air-conditioning (HVAC) systems. Its filter media is a nylon mesh woven from PP, PA or PE monofilament and mounted in an aluminium or nylon-edged frame, delivering high airflow at low initial resistance while capturing coarse dust and smoke particles. Because the media can be repeatedly washed and reused, the filter offers a long service life and low total cost of ownership.
Key Features
- High airflow with low initial resistance
- Washable and reusable – long service life
- Resistant to acid, alkali, oil mist and high temperature
- Effectively removes dust and smoke particles
