Vortex Powerfans V-Series – 12 in

Vortex Powerfan V-Series Inline Fan Built Around a Mixed-Flow Impeller The V-Series is the steel-bodied blower Atmosphere builds for rooms that outgrew an 8-inch fan. Its mixed-flow impeller sits between an axial and a squirrel cage. The 12-inch moves 2,050 CFM at 1,700 RPM and meters 53 dB max. The 14-inch turns 2,905 CFM at 1,500 RPM. The 16-inch reaches 4,515 CFM at 1,600 RPM. Impact-resistant heavy-gauge steel under a hammertone powder coat absorbs part of what the motor makes. The balanced impeller rides on permanently lubricated ball bearings. Nothing in the airstream is plastic. Sizing a High CFM Inline Duct Fan From 12 to 16 Inches Duct diameter sets the ceiling, so size off room volume and target exchange time. At 2,050 CFM the 12-inch turns over a 2,000 cubic foot room in about a minute, before filter losses. All three are 100% speed controllable, and that is how most rooms run them. Growers dial them back until the carbon filter's static pressure and the day's heat load call for full output. The extended collar and lip take duct without a fight. Galvanized brackets hang the fan horizontally or vertically off a factory 6 ft cord. Two honest limits. The 16-inch is 240V only. And at 44 to 69 lbs of steel, these want a mechanical room or an attic run, not a tent pole. Key Features Mixed-flow impeller: Moves centrifugal-class air volume at 1,500-1,700 RPM instead of spinning faster for it 2,050 to 4,515 CFM: Three duct sizes cover single-room exhaust up to whole-facility ventilation 53-60 dB maximum: Low enough that the duct run, not the motor, becomes the loudest part of the system 100% speed controllable: Trim output to the room's real load and cut both noise and motor wear Hammertone powder-coated steel: Rustproof and sound-absorbing in the humidity of a sealed flowering room Extended collar and brackets: Duct tapes up cleanly and the fan mounts horizontally or vertically on a 6 ft cord Technical Specifications Specification 12 in (736690) 14 in (736691) 16 in (736698) Airflow @ 0.0 SP 2,050 CFM 2,905 CFM 4,515 CFM RPM 1,700 1,500 1,600 Rated wattage 540 W 860 W 1,550 W Rated amperage 4.8 A 7.5 A 13.2 A Voltage / frequency 120V / 60Hz 120V / 60Hz 240V / 60Hz Maximum sound 53 dB 57 dB 60 dB Weight 43.8 lbs 54.3 lbs 68.8 lbs Dimensions (L x W x H) 19.3 x 19.3 x 24.0 in 22.0 x 25.5 x 21.0 in 23.0 x 23.0 x 28.0 in Speed controllable Yes, 100% Yes, 100% Yes, 100% Power cord 6 ft, factory installed 6 ft, factory installed 6 ft, factory installed
