Ruck 14 Inch S-Prime EVO EC at 1,960 CFM
1,960 CFM from a 14 inch duct, inside a sound insulated galvanized steel casing. The motor is the same stepless 0-10V EC unit at 120V. That makes it the largest single-phase fan in the line. Ruck does not publish watts or impeller speed for this size in the retail listings. That is a gap worth knowing about before a circuit gets designed around it.
Placing a Sound Insulated EC Inline Fan on a Trunk
A fan this size belongs on a trunk line serving several rooms rather than a single tent. Straight duct at both ends matters more here than on anything smaller. A 14 inch body loses more to a tight bend, and that loss never shows up on a spec sheet. Since the current draw is not published, size the circuit from the nameplate rather than any retail listing. Everything else carries over, from the insulated casing to the three-year German warranty.
