Ruck 14 inch Prime EVO EC Mixed Flow Inline Duct Fan | 1,930 CFM, 0-10V EC

The 14 Inch Prime EVO EC Against the 12 Inch

The comparison with the 12 inch is the interesting one. This moves 1,930 CFM on 244 to 257W, where the 12 inch needs a similar draw for noticeably less air. The difference is impeller speed, 1,868 to 2,173 RPM against nearly 3,200 on the smaller fan. A bigger blade turning slower is the more efficient machine, and this is where that shows most clearly. Maximum current is 3.1A and the unit weighs 16.1 lbs.

Fitting a 14 Inch EC Inline Duct Fan to a Trunk Line

A fan this size belongs on a trunk line serving several tents or rooms rather than one tent on its own. Straight duct at the inlet and outlet matters more here than on anything smaller, because a wide body loses more to a tight bend. The temperature rating is the one place it gives ground to the 12 inch. At -13°F to 104°F the ceiling is lower, and a hot attic in summer can reach it. Everything else carries over, from 0-10V control and ETL listing to the bracket, the 5.5 ft cord and three years of cover.
