Air filters shield emi, shed rain

Honeycomb Vent Panel air filters provide electronic cooling and EMI shielding, while maintaining clean, dry airflow in outdoor electronic enclosures such as traffic-control boxes, electrical and power-generation back-up systems, and wireless base-station huts.

Filters feature 30, 60, or 90°-slanted honeycombs. Units with the company's Quadrafoam filter media comply with Telcordia GR-487-CORE requirements for flame, fungus, and corrosion resistance. Those with Quadrafoam II also withstand dust intrusion and wind-driven rain. Filters for indoor use direct laminar airflow towards concentrated areas within the chassis.
