STI EP201608-O5 NEMA 3R Polycarbonate Filter Fan Vent
Overview
The EP201608-O5 is a NEMA 3R-rated filter vent engineered to manage thermal buildup in outdoor access control, telecommunications, and security equipment enclosures. Built from UV-resistant polycarbonate, this unit delivers passive airflow without requiring powered cooling—a critical advantage in remote gate installations, perimeter reader cabinets, or rooftop network enclosures where power draw must stay minimal or where equipment thermal cycling degrades over seasons of sun and weather exposure.
Compatibility
The EP201608-O5 mounts directly on standard outdoor security enclosures housing access control readers, credential processing hardware, and network switching equipment. Its passive design requires no electrical integration, making it compatible with any outdoor cabinet or junction box in the -40°F to +140°F operating range. The unit does not depend on specific reader models or systems—it functions as a standalone thermal and environmental management component for any metal or composite enclosure where dust infiltration and heat accumulation are concerns.
Installation Notes
Environmental Protection: NEMA 3R rating ensures protection against rain, sleet, and external ice formation—standard for perimeter security and gate control installations. The integrated filter cartridge reduces particulate ingress from dust storms and salt spray common in exposed environments. Mounting and Maintenance: Direct mounting on enclosure surfaces using standard hardware; no ducting or external venting required. Filter cartridges are accessible for routine cleaning or replacement without tools or enclosure disassembly. Thermal Performance: Passive convection airflow prevents equipment thermal degradation caused by sealed cabinet operation in direct sun or high ambient temperatures.
