Ruck S-Prime EVO EC HO 14 Inch EC Inline Fan for Large Rooms
The S-Prime EVO EC HO is a high-output 14-inch mixed flow fan from Ruck Air Movement. A Prime Evo EC mixed flow fan sits inside a sound insulated galvanized sheet steel casing. Maximum airflow is 2849 CFM, and the fan can work against up to 3.73 in.wg of static pressure. The EC motor runs on 240V single-phase, 60 Hz. It draws 731 W and up to 3.4 A at full output. Speed is stepless through a 0-10V input, so any compatible 0-10V controller can set it. Rated speed is 2865 rpm, with a maximum of 3000 rpm. Housing break-out noise measures 63 to 70 dB(A) sound power across the fan curve. The terminal box is rated IP44, and the complete unit carries an IPX4 rating. Air and surroundings can range from -13°F to 104°F. The fan measures 17.32 x 17.32 x 27.17 in and weighs 42.3 lb. It carries UL and CSA certification and a 3-year limited warranty.
Running a 0-10V Duct Fan on a Heavy Exhaust Line
This fan suits large grow rooms, warehouses and commercial spaces with a big carbon filter or a long trunk line. Have an electrician confirm a dedicated circuit at the right voltage before the fan arrives. Hang it from structure with hangers or brackets rated for its weight, never from the ducting. Mount the carbon filter on the inlet side and run the outlet duct to the exhaust point. Clamp both collars and seal every joint with foil tape. Wire a compatible controller, potentiometer or climate controller to the control input in the terminal box. Run the fan hard when lights are on and heat peaks. Turn it down overnight, when the room is cooler and needs less air. Lower speed also cuts noise and power use at the same time. The casing quiets the fan body, but a silencer on the outlet helps where the duct ends near people. A backdraft damper stops outside air returning when the fan slows or stops. Disconnect power before cleaning, and wipe dust from the impeller between crops.
