Core Advantages
The Whalesens WSE-S ultra-thin air filter is a tailor-made ideal protection solution for electric vehicle charging piles, especially suitable for common dusty environments such as city centers and highway service areas.
- Cost-Effective, Long-Term Savings: Featuring a unique washable design, when the filter becomes clogged, performance can be restored simply by cleaning it with a vacuum cleaner or rinsing it with clean water, allowing for repeated use. Compared to traditional disposable filters, this can significantly reduce the long-term operating and maintenance costs (OPEX) of charging stations.
- Dual-Layer Protection, Reliable Performance: Innovatively combines an open-cell foam layer with a high-efficiency moisture barrier layer. The open-cell foam effectively intercepts and retains larger dust particles, pollen, and insects from the air, while the moisture barrier resists rain splash and prevents moisture ingress, protecting the sensitive internal electronic components.
- Ultra-Thin Design, Strong Compatibility: Designed specifically for space-constrained charging piles, it features an integrally molded aluminum alloy frame with a thickness of just 7mm (0.28 inches, customizable dimensions). It can be easily installed without modifying existing equipment, making it a perfect choice for upgrading existing charging stations.
- Safe, Durable, Internationally Certified: Complies with the UL94 HF-1 flame retardancy standard, ensuring safe use under extreme conditions. Its robust construction resists water splash from all directions (effectively splash-proof), providing all-weather basic protection for outdoor charging piles.
