Overview

The nVent WeatherFlo Type 3R Enclosure with Fan (SKU: WF40LP) provides forced-air cooling for high-heat industrial equipment in outdoor environments. This 47.00 x 24.00 x 14.00 inch enclosure features a factory-installed 115 VAC axial fan with washable metal filter, delivering 200 CFM of airflow to prevent thermal overload in drives, VFDs, and motor controllers. The adjustable thermostat (70–140°F) automatically activates cooling when internal temperatures rise, while the integrated solar shield top and intake cover minimize heat gain from direct sunlight. Built to UL 508A, cUL, NEMA Type 3R, and IEC 60529 IP32 standards, the WF40LP protects against rain, dust, and temperature extremes. The white polyester powder finish (RAL 9003) reduces solar absorption, extending equipment lifespan. Designed for easy installation and maintenance, it includes a lift-off hinged door with quarter-turn latch, gasketed sealing, external mounting brackets, and grounding provisions. Compatible with nVent accessories like electric heaters and swing-out panel kits, the WF40LP is ideal for outdoor substations, pump houses, HVAC systems, and renewable energy installations.
