Description
The HF-NL Nylon Mesh Filter is designed for primary dust protection in EV charging points, fast-charging stations, charging cabinets and outdoor electrical enclosures.
Made from black PP fiber woven mesh, the filter provides high airflow capacity, ultra-low initial resistance and reliable interception of coarse airborne contaminants. Installed at the cooling-air inlet of a charging point, it helps prevent dust, fibers, insects and outdoor debris from entering fans, heat sinks, charging modules, circuit boards and electrical control components.
The washable and reusable construction makes it suitable for charging equipment requiring frequent maintenance, low lifecycle cost and continuous cooling airflow. Standard 10 mm and 21 mm depths are available, with custom dimensions and mesh specifications supported for OEM charging-system projects.

|---|---|---|---|---|
| HF-NL | 595 × 595 × 10 | 3,400 | 10 | G1 / 60% |
| HF-NL | 495 × 595 × 10 | 3,200 | 10 | G1 / 60% |
| HF-NL | 295 × 595 × 10 | 2,000 | 10 | G1 / 60% |
| HF-NL | 595 × 595 × 21 | 3,600 | 15 | G1 / 65% |
| HF-NL | 495 × 595 × 21 | 3,400 | 15 | G1 / 65% |
| HF-NL | 295 × 595 × 21 | 2,200 | 15 | G1 / 65% |
Average arrestance is shown for coarse particles larger than 10 μm using the gravimetric method. Actual performance may vary according to airflow, mesh density, dust loading, sealing condition and equipment design.

Applications
| EV Fast-Charging Stations | Charging Cabinets and Piles | Power and Control Compartments | OEM Charging Equipment Integration |
|---|---|---|---|
| Installed at cooling-air inlets of DC fast chargers to prevent coarse dust, insects and debris from entering high-power charging modules. | Used in AC charging piles and charging cabinets to maintain ventilation airflow while reducing contamination inside the enclosure. | Suitable for power conversion modules, cooling fan sections, control boards and electrical compartments requiring dust-protected airflow. | Designed for EV charger manufacturers, charging infrastructure suppliers and enclosure producers requiring standard or customized washable filters. |
Benefits for Charge Point Systems
| Ultra-Low Airflow Resistance | Reusable Maintenance | Internal Equipment Protection | Compact Installation |
|---|---|---|---|
| Initial resistance of only 10–15 Pa helps preserve the cooling airflow required by high-power charging equipment. | The PP mesh can be washed and reused, reducing replacement frequency and lifecycle cost. | Coarse contaminants are intercepted before reaching cooling fans, heat sinks, power modules and circuit boards. | The 10 mm slim model is suitable for charging piles and cabinets with limited filter space. |
