Ruck 12 inch Prime EVO EC Mixed Flow Inline Duct Fan | 1,448 CFM, 0-10V EC

Where the 12 Inch Prime EVO EC Gets Efficient

This is the size where the line stops being merely powerful and starts being efficient. 1,448 CFM comes from somewhere between 217W and 261W depending on where it sits on the curve, drawing at most 3.1A. Impeller speed ranges from 2,945 to 3,195 RPM. Ruck rates it from -13°F to 131°F, the widest span in this family. The motor sits at IP30 behind an IP44 terminal box, and the unit weighs 15.7 lbs.

Running a 12 Inch EC Inline Duct Fan Day to Day

This size makes sense when a room ventilates continuously rather than switching on and off. An EC motor holds a set point without cycling, so humidity drifts less and the room stays more even through the day. Weight is the thing to plan for. It needs a proper hanger rather than a duct strap, and it should never rest on the ducting itself. That wide temperature rating means an unheated outbuilding is well within range. Stepless 0-10V control, a mounting bracket, a 5.5 ft cord and three years of German warranty come as standard.
