Ruck 8 inch Prime HO Mixed Flow Inline Duct Fan | 946 CFM, 217W

Ruck 8 Inch Prime HO Mixed Flow Moves 946 CFM

The HO version of the 8-inch Prime trades watts for air. 946 CFM against 656 from the standard, for 217W and 1.8A instead of 176W and 1.6A. That is a good exchange rate. It keeps the plastic housing, the 3D impeller and the 5.5 ft cord. It also adds an integrated 3-speed switch the standard model lacks.

Where a High Output Mixed Flow Fan Is Worth It

Choose HO when the standard 8-inch runs out of pressure: a long duct, several elbows, or a filter you do not change often. In an easy run it is unnecessary and you will just hear more fan. The 3-speed switch helps here, since you can take the headroom and run it on low most of the time. Plastic housing keeps weight down but transmits more noise than the metal-cased sizes, so isolate it at the joints. Keep the run straight where you can, since elbows cost more pressure than people expect. Give the joints a rubber coupling if the fan sits above a quiet room.

Key Features

• 946 CFM: Mixed flow output that holds pressure against a loaded filter.
• 217W at 1.8A: Published draw on 120V, so the circuit can be planned properly.
• 3D Shaped Impeller: The blade form Ruck uses to lift efficiency and drop noise.
• Plastic Housing: Keeps weight low, though it carries more noise than metal.
• 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.
