Ruck 8 inch Classic Centrifugal Fan. 527 CFM, 115W, Metal Casing

What the 8 Inch Classic Centrifugal Fan Delivers At 8 inches the Classic starts to look efficient rather than merely adequate. 527 CFM on 115W and 1.00A is a better airflow-per-watt figure than either smaller size manages. Backward curved impeller, powder-coated metal casing, incorporated mounting brackets. It carries a three-year warranty and ships with a 5.5 ft cord. Placing This Inline Duct Fan in the Run An 8-inch Classic suits a small room or a tent pair sharing one exhaust. Put it downstream of the filter, hung on its own strap, with the brackets that come fitted to the casing. Static pressure is where centrifugal fans earn their money. A long run with two or three elbows will not collapse the airflow the way it would with an axial booster. It is still a metal-cased AC fan, so expect industrial noise rather than tent-fan quiet. Plan a silencer if the room is anywhere near living space. Controller choice matters at this size. The motor is voltage controllable but not suitable for solid-state speed controls, so use an autotransformer. Key Features 527 CFM: Centrifugal output that holds up against a loaded carbon filter. 115W at 1.00A: Real draw at 120V, so the circuit load is easy to plan. Backward Curved Impeller: The blade form that keeps pressure up on long duct runs. Powder-Coated Metal Casing: Metal rather than plastic, and corrosion-resistant in damp air. Incorporated Mounting Brackets: Fitted to the casing, so it hangs without extra hardware. 5.5 ft Power Cord: Reaches a socket or controller without an extension in most tents. Voltage Speed Control Only: Not suitable for solid-state controllers, so use an autotransformer. 3-Year Warranty: German-built, and covered for three years.
