Abstract
In one aspect, a system for controlling an air intake system for a work vehicle may generally include a filter assembly having a pre-cleaner configured to separate particulates from air received by the filter assembly. The pre-cleaner may define a pre-cleaner outlet. The system may also include an electric aspirator in fluid communication with the pre-cleaner outlet. The electric aspirator may include a motor configured to rotate a fan so as to create a vacuum for scavenging the particulates separated from the air within the pre-cleaner. In addition, the system may include a controller communicatively coupled to the electric aspirator. The controller may be configured to vary a rotational speed of the motor based on changes in a load-based parameter of the work vehicle.
