TThe Weather Resistant Filter solution delivers outstanding protection for electronics enclosures deployed in harsh outdoor environments, allowing designers to utilize ambient air to cool vented systems, increasing efficiency and reducing operating costs compared to closed systems with limited heat dissipation capacity. Custom Weather Resistant Filter solutions limit ingress of dust, water, and salt fog into electronics enclosures using fresh air intake and direct air-cooling systems instead of costly, inefficient, closed loop heat exchangers. This is an ideal solution for outdoor video displays and kiosks, power generation, security, military/defense, telecom, and any other industrial or commercial outdoor enclosures installed in harsh environments.
The Weather Resistant Filter was developed with a unique three-stage approach, incorporating a high-efficiency main filter and a coarse low-efficiency prefilter with water resistant mesh. An open-cell polyurethane foam pre-filter with a treated hydrophobic mesh layer is used to capture coarse dust particles. This knocks down the majority of the potential water ingress. Furthermore, a high-efficiency primary filter is used to capture fine dust and airborne water droplets. Weather Resistant FiltersThe Weather Resistant Filters feature a lower pressure drop to ensure longer filter life and maintenance cycles. Additionally, the Filters meet industry compliance standards for RoHS/REACH and UL flammability, IP55 and Telcordia NEBS GR-487 (salt fog).
