Description
The Foldaway Paper Frame Filter Mesh is designed for dust protection and airflow filtration in electric vehicle charging stations, charging cabinets, power distribution enclosures and outdoor electrical equipment.
Featuring a pleated synthetic fiber filter media combined with a moisture-resistant paper frame, this lightweight panel filter provides high dust-holding capacity, low airflow resistance and reliable particle capture performance.
Installed at the air inlet of charging equipment, the filter prevents dust, fibers, sand particles and airborne contaminants from entering internal cooling components, helping protect fans, heat sinks, power modules and electronic control systems.
With G3 and G4 filtration options, the filter provides an economical and efficient solution for EV charging infrastructure manufacturers requiring stable ventilation protection and customized OEM filter designs.
