Abstract

A filter system and method use a filter housing that defines an interior chamber and that includes an inlet opening extending into the interior chamber. The outer air flow housing has an outlet conduit through which a flow of air having particles is directed toward the inlet opening of the filter housing along a flow direction toward the interior chamber of the filter housing. The outer air flow housing engages the filter housing such that the filter housing is separated from the outer air flow housing along the flow direction to permit at least some of the air to pass around an exterior of the filter housing and exit the outer air flow housing while the particles in the at least some of the air pass into the interior chamber of the filter housing through the inlet opening.
