Overview

The nVent WeatherFlo Type 3R Fan Enclosure (SKU: WF75LP) delivers forced-air cooling for high-heat industrial equipment in outdoor environments. Constructed from durable aluminum with a low-solar-absorption white polyester powder finish (RAL 9003), this enclosure measures 56.00 x 36.00 x 16.00 inches. Its active ventilation system includes a factory-installed 115 VAC axial fan and washable metal filter, controlled by an adjustable thermostat (70–140°F) for automatic operation. The integrated solar shield top and intake cover minimize heat gain, while the gasketed door with quarter-turn latch and lift-off hinges ensures weather-resistant access. A top front hood exhaust efficiently expels heated air. External mounting brackets and grounding provisions simplify installation. Designed for Type 3R applications, it meets UL 508A, cUL, NEMA Type 3R, and IEC 60529 IP32 standards. Ideal for cooling VFDs, motor controllers, and PLCs in outdoor substations, pump houses, and telecommunications shelters.
