Description
The HF-JS Metal Mesh Air Filter is a washable and reusable primary filtration solution developed for energy storage boxes, containerized battery energy storage systems, battery cabinets and PCS ventilation compartments.
Constructed with multiple layers of corrugated aluminum mesh and a stainless-steel support layer, the filter provides high airflow capacity, low initial pressure drop and reliable mechanical strength. It captures coarse dust, fibers, insects and airborne debris before they enter battery compartments, cooling fans, heat exchangers and sensitive electrical equipment.
Its all-metal construction offers good resistance to heat, moisture, cleaning chemicals and repeated maintenance. With 21 mm, 25 mm and 46 mm depth options, the filter can be selected according to available installation space, airflow requirements and site dust conditions.

Applications
| Containerized BESS Units | Battery Cabinet Cooling | PCS & Inverter Compartments | OEM Energy Storage Equipment |
|---|---|---|---|
| Used as a washable first-stage intake filter in containerized battery energy storage systems to reduce the entry of coarse dust and outdoor debris. | Installed upstream of cooling fans, coils and heat exchangers to help maintain clean airflow passages and stable thermal management. | Suitable for PCS modules, inverter cabinets, UPS compartments and electrical control sections requiring continuous filtered ventilation. | Designed for BESS integrators, battery cabinet manufacturers, enclosure suppliers and cooling-system producers requiring standard or customized metal filters. |
Benefits for Energy Storage Boxes
| High Cooling Airflow | Reusable Maintenance | Equipment Protection | Demanding-Environment Durability |
|---|---|---|---|
| Low initial resistance helps preserve the airflow required for battery cooling and enclosure temperature control. | The all-metal filter can be cleaned and returned to service, reducing disposable-filter consumption. | Coarse particles are intercepted before reaching batteries, fans, heat exchangers and power electronics. | Metal construction provides reliable strength under heat, humidity, vibration and repeated cleaning. |
