1. A filter system comprising:
a filter configured to receive a first fluid mixture via an inlet, the first fluid mixture comprising a first fluid and debris, the filter shaped to separate a portion of the debris from the first fluid;
a fluid control device fluidly coupled with the filter, the fluid control device configured to receive the first fluid from the filter and change a characteristic of the first fluid to form a second fluid within the fluid control device, the fluid control device configured to direct a first portion of the second fluid out of the fluid control device via a first outlet of the fluid control device and direct a second portion of the second fluid out of the fluid control device via a second outlet of the fluid control device; and
a conduit fluidly coupled with the filter and the fluid control device, the conduit configured to receive the portion of the debris from the filter and the second portion of the second fluid from the fluid control device,
the conduit extending along an axis and comprising a section including an increasing cross-sectional size along the axis, the conduit configured to receive the portion of the debris and the second portion of the second fluid at a location that is upstream along a direction of flow from the section including the increasing cross-sectional size, the conduit configured to combine the portion of the debris with the second portion of the second fluid within the conduit upstream of the section including the increasing cross-sectional size to form a second fluid mixture, the conduit shaped to control one or more of a pressure or a velocity within the conduit to direct the second fluid mixture through the conduit toward an outlet.
