Ruck 14 inch Prime EVO EC HO Mixed Flow Inline Duct Fan. 2,819 CFM, 0-10V EC

What High Output Means on a 14 Inch Duct HO stands for high output, and here it means 2,819 CFM out of a 14 inch duct. That is some 46 percent more air than the standard Prime EVO EC version manages. Maximum current is 3.4A at 120V. The motor is rated IP20 rather than the IP30 or IP54 used elsewhere in the range, so it prefers a drier mounting position. It is ETL listed and rated down to -13°F. When a High Output EC Inline Fan Is the Right Call Reach for the high output version when the duct size is fixed and the standard fan cannot keep up. Long runs, heavy filter banks and rooms with high air-change targets are the real cases. If the ducting can grow instead, the 16 inch moves more air for a similar current and is usually the better call. The lower motor rating is the thing to design around, so keep this one well clear of splash zones and standing damp. It comes with 0-10V control and three years of warranty.
