Ruck 20 inch Prime Mixed Flow Inline Duct Fan | 4,595 CFM, 1004W

Ruck 20 Inch Prime Mixed Flow Moves 4,595 CFM At 4,595 CFM this is room-scale equipment. It runs on 240V, drawing 4.2A and 1,004W, inside an aluminium shell with an IP54 motor and an integrated 3-speed switch. The operating ceiling is 104°F, lower than the 18 inch, which is worth checking against a hot plant room before fitting. Sizing a Grow Room Ventilation Fan at 4,595 CFM This belongs in a commercial room or a large greenhouse rather than a garage. Confirm the circuit, then hang it on dedicated supports. The 3-speed switch lets you size for the top figure and live at a lower one, which is quieter and easier on the motor. Ambient temperature is worth watching given that ceiling. Keep the runs short and the elbows few, because a fan this size loses real airflow to a badly routed duct. Leave clear access at both collars so the impeller can be cleaned without dropping the fan. Key Features 4,595 CFM: Mixed flow output that holds pressure against a loaded filter. 1004W at 4.2A: Draw on 240V, so the circuit can be planned properly. 3D Shaped Impeller: The blade form Ruck uses to lift efficiency and drop noise. Aluminum Housing: Light for the size and easy to handle. Mounting Bracket Included: Hangs on its own support rather than loading the ductwork. Motor in the Hub: The motor sits inside the fan hub, out of the weather and the dust. Integrated 3-Speed Switch: Step output down at night without extra hardware.
