Description
The G3/G4 Heat-Resistant Panel Air Filter is developed for primary air filtration in energy storage boxes, containerized battery energy storage systems, battery cabinets and power conversion equipment compartments where ventilation air may be exposed to elevated temperatures.
Manufactured with imported organic synthetic fiber media and a rigid metal frame, the filter offers high airflow capacity, controlled pressure drop and stable structural performance. It captures coarse dust, fibers and airborne debris before they reach battery modules, cooling fans, heat exchangers, PCS units and electrical control components.
Available in G3 and G4 configurations with multiple panel depths, the filter can be customized to match different BESS enclosure openings, cooling modules and thermal-management requirements.
Technical Parameters
| Grade | Size (mm) | Rated Airflow (m³/h) | Average Arrestance | Initial Pressure Drop (Pa) | Recommended Final Resistance (Pa) | Frame |
|---|---|---|---|---|---|---|
| G3 | 500 × 500 × 15 | 1,000 | 86% | 45 | 180 | Aluminum Alloy / Galvanized Steel |
| G4 | 500 × 500 × 25 | 1,200 | 90% | 50 | 200 | Aluminum Alloy / Galvanized Steel |
| G4 | 500 × 500 × 46 | 1,200 | 90% | 50 | 200 | Aluminum Alloy / Galvanized Steel |
The listed values are nominal specifications. Actual airflow, resistance and service life may vary according to operating temperature, face velocity, dust concentration, sealing condition and system design.

Applications
| Containerized BESS Units | Battery Cabinet Thermal Management | PCS & Electrical Compartments | OEM Energy Storage Integration |
|---|---|---|---|
| Used as the first-stage air filter in containerized energy storage systems to reduce dust entry into battery racks and internal cooling areas. | Installed upstream of cooling fans, coils and heat exchangers where ventilation air may operate at elevated temperatures. | Suitable for PCS units, inverter cabinets, UPS compartments and electrical control sections requiring filtered cooling air. | Designed for BESS integrators, battery cabinet manufacturers, container suppliers and cooling-system producers requiring standard or customized filters. |
Benefits for Energy Storage Boxes
| Thermal Stability | Cooling Airflow Support | Equipment Protection | Flexible System Integration |
|---|---|---|---|
| Heat-resistant media provides improved stability in warmer ventilation sections compared with conventional primary filters. | Controlled pressure drop helps maintain the airflow needed for battery and power-electronics cooling. | Coarse particles are intercepted before reaching battery racks, fans, coils, sensors and electrical components. | Multiple grades, depths and metal-frame options support different BESS enclosure and cooling-module designs. |
