Hyper Fan: 5 year warranty with most efficient fan motor on the market. Multi-Phase motor uses of half the power of traditional EC or DC motors. 6" fan is 35w -- 0.5 amps @ 120v. Hyper Fan: Lightweight aluminum housing is one-third the weight of comparable steel bodied fans. Universal mounting positions. Hyper Fan combines Laminar Blade Design and Stator Technology inspired by the modern jet engine, to reduce noise, increase airflow and create the highest static pressure performance of any fan in it's class. Black Ops: 2 year life expectancy. Make of virgin Activated Australian RC-412 granular carbon. Light weight (13 lbs). Black Ops filters have a built in flange and 2 pre-filters are included. Note: Flange on Black Ops filter is slightly larger than 6". This is to allow 6" fans and other flanges to sit inside the flange of the carbon filter. We recommend cutting a slit in the ducting to make it fit over the Black Ops flange, then taping the ducting for an air tight seal.
