Claim 0:
1. An electromagnetic interference (EMI) attenuation device comprising:
a housing stator having an aperture therethrough, wherein at least a portion of the housing stator is electrically conductive;
a fan rotor adjacent to the aperture and having a rotational axis relative to the housing stator and a proximate surface proximate the housing stator, wherein the fan rotor is electrically conductive and the proximate surface is continuous around a rotational direction of the fan rotor and the fan rotor allows fluid flow through the fan rotor and aperture; and
an electrical bridge between the proximate surface of the fan rotor and a contact surface of the housing stator.
