Abstract
A damper for controlling fluid flow may include a main body, a stator that includes a plurality of stator blades, and a rotor moveably connected to the stator and including a plurality of rotor blades. The damper may also include a rotation mechanism mounted to the main body to move the rotor between an opened position and a closed position. The shape of each of the plurality of stator blades and rotor blades may combine to form a shape such that the velocity of the fluid is increased thereby reducing or eliminating back pressure when the rotor is in the opened position.
