Ruck 12 inch Prime Mixed Flow Inline Duct Fan | 1,684 CFM, 449W

Ruck 12 Inch Prime Mixed Flow Moves 1,684 CFM The 12 inch Prime is the one size in the range where it is worth pausing to compare. It moves 1,684 CFM, but draws 449W at 4.0A to do it. The 14 inch Prime moves more air, 1,758 CFM, on 226W. If your duct can take 14 inches, it costs far less to run. Where 12 inches is fixed by the ductwork, this is a solid galvanized-steel, IPX4 unit with a 3-speed switch. Sizing a Grow Room Ventilation Fan at 1,684 CFM If the duct is already 12 inches, fit it and move on, because it is a well-built fan. Use the bracket, keep the run short, and set the 3-speed switch to the lowest step that holds your target exchange. Circuit capacity deserves a look, because that draw is a real load and on a 15A circuit shared with lighting it does not leave much. The galvanized housing and IPX4 rating handle humidity without complaint, which matters in a room that runs wet through flower. Key Features 1,684 CFM: Mixed flow output that holds pressure against a loaded filter. 449W at 4.0A: Draw on 120V, so the circuit can be planned properly. 3D Shaped Impeller: The blade form Ruck uses to lift efficiency and drop noise. Galvanized Steel Housing: Rigid and corrosion-resistant in damp exhaust air. 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.
