Description
The G3/G4 Panel Pre-Filter is designed for primary air filtration in energy storage boxes, battery energy storage systems (BESS), containerized battery cabinets and power conversion equipment enclosures.
Installed at fresh-air inlets, cooling-air openings or ventilation sections, the filter captures coarse dust, fibers and other airborne contaminants before they enter battery compartments, cooling fans, heat exchangers, PCS modules and electrical control areas.
The pleated synthetic fiber media provides high air permeability, low initial pressure drop and good dust-holding capacity. These characteristics help maintain the continuous cooling airflow required by energy storage systems while reducing dust accumulation on internal equipment.
Standard G3 and G4 models are available with aluminum-alloy or galvanized-steel frames. Custom dimensions, frame structures and airflow configurations can be manufactured for different BESS container designs and enclosure ventilation requirements.

|---|---|---|---|
| Used as the first-stage intake filter in containerized BESS units to reduce dust entry into battery racks, monitoring systems and thermal-management components. | Installed at fresh-air openings and cooling fan inlets to protect coils, heat exchangers and airflow passages from coarse particle accumulation. | Suitable for PCS modules, inverter cabinets, control compartments, UPS enclosures and auxiliary power sections requiring continuous filtered ventilation. | Designed for energy storage system integrators, battery cabinet manufacturers, container suppliers and ventilation equipment producers requiring standard or customized filters. |
| Stable Thermal Management | Battery and Equipment Protection | Low Fan Load | Reduced Maintenance |
|---|---|---|---|
| Low initial resistance helps preserve the airflow required to control battery and enclosure temperatures. | Coarse contaminants are intercepted before reaching battery racks, fans, coils, sensors and power electronics. | High-permeability media reduces unnecessary pressure loss and additional load on ventilation fans. | High dust-holding capacity can extend cleaning intervals and reduce contamination of internal cooling components. |
