The 10 Inch S-Prime EVO EC and Its 1,271 CFM
This is the size where the line stops being a tent fan and starts serving a room. 1,271 CFM comes from 298W at up to 3.5A, with the impeller reaching 3,900 RPM, the fastest in the family. The motor rating steps down to IP30 here, where the 6 and 8 inch use IP54, so it prefers a drier mounting position. The terminal box stays IP44 and the complete unit is IPX4, with weight at 23.1 lbs.
Hanging a Sound Insulated Duct Fan This Heavy
At that weight and 27 inches long, mounting is the first thing to sort out. Two hangers hold it more comfortably than one, and the ducting should never carry the load. Straight duct either side is worth arranging as well, because a body this wide loses real airflow to a tight elbow at the inlet. Run it below full tilt on the 0-10V input wherever the room allows. It is quieter there, it draws less, and the motor has an easier life. Ruck builds it in Germany and covers it for three years.
