Abstract
Compact centrifugal fan and filter assemblies for use in providing laminar flow clean air to a work space environment such as those within clean rooms and clean air work stations or cabinets wherein the fan and filter element are mounted in a close physical relationship with respect to one another and within a common plenum chamber and wherein the fan creates an airflow which is initially generally parallel with respect to the filter element and which is thereafter channeled by baffle members so as to provide uniform air pressure and airflow across the filter element while reducing vibration and increasing the air flow rate from the fan and filter assemblies to such clean air environments.
