Ruck S-Prime EVO EC 6 Inch EC Duct Fan for Quiet Rooms
The 6-inch S-Prime EVO EC from Ruck Air Movement combines an EC motor with a sound insulated casing. Inside the galvanized sheet steel shell sits a Prime Evo EC mixed flow fan. Maximum airflow is 430 CFM, and the fan can work against up to 1.49 in.wg of static pressure. The EC motor runs on 120V, 60 Hz. It draws 72 W and up to 1 A. Speed is stepless through a 0-10V input, so any compatible 0-10V controller can set it. Rated speed is 3735 rpm, with a maximum of 3790 rpm. Housing break-out noise measures 53 to 58 dB(A) sound power across the fan curve. The motor is rated IP54, the terminal box IP44 and the complete unit IPX4. Air and surroundings can range from -22°F to 104°F. The fan measures 11.02 x 12.01 x 27.17 in and weighs 17.0 lb. It plugs into a standard outlet and carries UL and CSA certification. Ruck backs it with a 3-year limited warranty.
Running a Sound Insulated Inline Fan Near Living Space
This fan suits a grow space, office or studio that shares a wall with bedrooms or living areas. Hang it from a joist or frame with straps rated for its weight, rather than letting the ducting carry it. Plan for its length, since it needs a straight section of run to sit in. Connect a carbon filter to the inlet side and duct the outlet outdoors. Clamp both collars and seal the joints with foil tape. Wire a compatible controller, such as the Ruck MTP 21, to the control input. A controller lets the fan hold one steady speed instead of switching on and off. That keeps humidity steadier through the night. Turning it down lowers noise and power draw at the same time. A silencer on the outlet helps where the duct ends close to people. Unplug it before cleaning, and wipe dust off the impeller between crops.
