Ruck 16 inch Prime EVO Mixed Flow Inline Duct Fan | 2,342 CFM, 299W, 3-Speed

The 16 Inch Prime EVO and Its Slow Blade

At 16 inches the impeller slows right down, to 1,715 RPM, and the efficiency figures change character completely. 2,342 CFM on 299W and 2.5A works out at about 7.8 CFM per watt. A big slow blade moves more air per watt than a small fast one. The housing is still injection moulded plastic and still IPX4, with the same three-speed switch fitted to the casing.

Placing a 16 Inch Inline Duct Fan in Commercial Ducting

This is commercial ducting territory rather than tent equipment. Sixteen inch trunk lines, a bank of filters, or a room needing several air changes an hour are the conditions it suits. Circuit capacity and physical clearance both deserve checking before it goes in. A body this size needs straight duct either side to reach its rated flow. A tight elbow at the inlet costs more than the spec sheet suggests. Retailer listings disagree on wattage here, with figures as high as 350W in circulation. The manufacturer number above is the one to plan around. The bracket and a 5.5 ft cord come in the box. The warranty runs three years.
