Ruck Classic HO 10 Inch Inline Duct Fan for Exhaust and Supply
The Classic HO is a 10-inch inline centrifugal fan from Ruck Air Movement. Its backward-curved impeller sits in a powder-coated metal casing with built-in mounting brackets. Maximum airflow is 806 CFM, and the fan can work against up to 3.29 in.wg of static pressure. The one-phase AC motor runs on 120V, 60 Hz. It draws 286 W and up to 2.5 A at full speed. Rated speed is 2730 rpm, with a maximum of 3360 rpm. Speed is voltage-controlled, so a compatible variable-voltage controller can turn it down. The data sheet lists 40 V as the lowest allowed control voltage. The motor carries insulation class F and an IP33 rating. Ambient and conveyed air can range from -13°F up to 113°F. The fan weighs 12.1 lb and measures 9.84 x 13.78 x 15.75 in. A 5.5-ft power cord comes attached. It carries UL and CSA certification.
Running a Centrifugal Fan with a Carbon Filter
Ruck builds this fan for residential, commercial and light industrial ventilation, including grow rooms, attics, basements and HVAC duct runs. In a grow room, it usually pulls air through a carbon filter and pushes it out of the space. Mount it to a wall, joist or frame with the built-in brackets. Connect the carbon filter or intake duct to the inlet side, and run the outlet duct to the exhaust point. Clamp both collars and seal the joints with foil tape. Keep duct runs short and avoid sharp bends right at the fan, since each one adds resistance. The outlet side is the louder side, so a muffler or insulated flexible duct there keeps noise down. A backdraft damper on the outlet stops air flowing back while the fan is off. Set the controller so the room holds its temperature target at the lowest speed that works. Keep the fan away from air hotter than its rated limit, such as a hot lamp exhaust. Unplug it and wipe dust from the impeller blades between crops to hold airflow up.
