Rotary components are described that include a housing comprising a rotor having a rotor working face and a gate having a gate working face and a pocket; at least one vane, wherein the vane is coupled to the rotor; at least one wiper coupled to the vane; a plurality of endplates coupled to the housing, wherein at least one of the endplates is a float plate; an intake chamber; and an outlet chamber. In addition, methods of aspirating a working medium by utilizing the rotary component having at least one float plate includes pulling the working medium into the intake chamber, depositing the working medium into a working chamber that is located between the intake chamber and the outlet chamber; maintaining the working medium in a stationary position until the vane sweeps around toward the outlet chamber; accumulating the working medium into the outlet channel of the outlet chamber; and centrifugally ejecting the working medium into the outlet chamber and out of the system.
