Hyper Fan's Laminar Flow Fan Blade & Stator Technology create optimal airflow similar in design to an airplane jet engine. The result is very high CFM s and exceptional static pressure performance. The Hyper Fan Stealth delivers the highest CFM s per watt of any silenced fan in the industry. The same state-of-the-art digitally controlled electronically commutated motor (ECM) and heavy-duty sealed ball bearings which make the original Hyper Fan so reliable and quiet, are combined with our silencing canister and lightweight acoustic foam in the Stealth series. This results in a reduction of 15DBA s which is perceived to the human ear as 75% quieter. Like the original Hyper Fan, the Stealth fans use 50% less power than traditional fans. A speed controller and integrated mounting brackets are included.
