EPUBLIC MANUFACTURING Republic offers a complete line of centrifugal blowers for vacuum or compressed air applications. Centrifugal blowers provide dry, clean, oil-free air and require low energy consumption. Unlike compressed air systems, this series is safe to run at low pressure, and allows for increased production speeds or levels. CENTRIFUGAL BLOWER The RB4000 provides the most flow of the centrifugal series. The blower comes with ceramic hybrid bearings, 360 degree rotatable outlet discharge, easy to remove stainless steel bearing housing assembly, and zinc plated steel motor pulley.
