Ruck S-Prime Evo 8 Inch Sound Insulated Fan for Grow Rooms
Ruck's 8-inch S-Prime Evo houses a Prime Evo mixed flow fan in a sound insulated galvanized sheet steel casing. The lining cuts the noise that radiates from the fan body. Maximum airflow is 783 CFM, and the fan works against up to 1.73 in.wg of static pressure. The one-phase AC motor runs on 120V, 60 Hz, drawing 184 W and up to 1.6 A. A 3-speed switch built into the fan sets the output. Rated speed is 3125 rpm, with a maximum of 3350 rpm. Housing break-out noise measures 61 to 64 dB(A) sound power across the fan curve. The terminal box is rated IP44, and the complete unit carries an IPX4 rating. It runs in air and surroundings from -13°F to 104°F. The fan measures 12.6 x 13.58 x 27.17 in and weighs 21.2 lb. It plugs into a standard outlet and carries UL and CSA certification. Ruck covers it with a 3-year warranty.
Installing a 3-Speed Inline Duct Fan on a Grow Room Exhaust
This fan suits mid-size grow rooms, workshops and greenhouses where a quieter exhaust helps. Hang it from structure with straps or brackets rated for its weight, rather than from the ducting. Allow for its length, since it needs a straight section of duct to sit in. Put the carbon filter on the inlet side and duct the outlet to the exhaust point. Clamp both collars and seal every joint with foil tape. Give the room a lower intake so fresh air can replace the exhaust. Use the high setting while the lights are on and heat peaks. Drop to a lower speed overnight, when the room needs less air. A silencer on the outlet helps if the duct ends near people. A backdraft damper stops cold air drifting back when the fan is off. Disconnect power before cleaning, then wipe dust from the impeller between crops.
