TrolMaster Aero-Fan HE-20M 20 inch High Velocity Fan. 4,980 CFM, IP66

The HE-20M Moves 4,980 CFM on 610 Watts 150 Pa of maximum static pressure is what separates this from a hardware-store fan, because it keeps pushing when the air has somewhere to go. IP66 means the motor is sealed against dust and water jets, not merely splashes. Airflow peaks at 4,980 CFM from a 610W motor pulling 3.0A. Voltage sensing is automatic across 200-277VAC. Five blades, and 29.76 lbs on the hanger. Placing a 20 Inch High Velocity Fan in a Room Mount it high and aim along the canopy rather than down into it. A fan this size is for moving the whole room's air in a loop, not for cooling one bench. Rated ambient range is -4°F to 140°F and mean time to failure is 50,000 hours at 25°C. The catch is the supply. This needs 200-277VAC, so a standard 120V outlet will not run it. The included ECS-7 cable connects it to a TrolMaster controller, and without one you lose the speed and scheduling control that justify the price. Key Features 4,980 CFM Maximum: Enough to turn over the air in a full commercial room. 610W, 3.0A: Real draw at the top of the range, useful for load planning. 200-277VAC Auto-Sensing: Adapts to the supply without a jumper or a switch. 150 Pa Static Pressure: Keeps moving air when the path is not wide open. IP66 Rated: Sealed against dust and water jets, not just splashes. Five-Blade Rotor: Turns counter-clockwise, 29.76 lbs assembled. ECS-7 Cable Included: Connects straight to a TrolMaster controller. 50,000 Hour MTTF: Manufacturer figure at 25°C ambient.
