Steel 38 Dia 39 L 30 H Roof Fan w.Motor

Engineered with durable steel construction for industrial settings, this roof fan provides an ideal solution for facilities seeking high-performance ventilation systems while maintaining quality air indoors through reliable exhaustion of heat or fumes during operation hence minimizing health hazards related to poor indoor air quality. The rugged design ensures that this versatile roof fan operates efficiently in humid, hot environments like agriculture or warehouses requiring robust ventilation systems that are energy-efficient while allowing customizable airflow direction using the variable speed controls thus cutting on energy costs, and maintaining smooth operation overtime making it essential for HVAC or refrigeration industries needing long-lasting reliable solutions cost-effectively.

This exhaust ventilator is for use in industrial and commercial buildings, including warehouses, manufacturing facilities, foundries, and laboratories. It's highly weather-resistant, with housings constructed of heavy-gauge galvanized steel, bolted seams, and reinforced edges for added strength. Drive frames are die-formed, galvanized structural steel, providing a rigid platform for motors, shafts, bearings, and drives. Fabricated steel propellers have steeply pitched blades to generate low sound levels. Integral butterfly dampers prevent unwanted backdrafts and have magnetic latches to minimize damper flutter when not in use. Built-in lifting lugs speed installation; the windband is removable for easy inspection.
