The FSD Series Water Separators have been designed for the efficient removal of bulk liquid contamination from compressed air. The Super-Dry water separators use centrifugal motion to force liquid water out of compressed air. Each centrifugal separator comes with a built-in float drain and an internal spinner. That removes large quantities of condensate by centrifugal action. Centrifugal water separator designs are installed upstream of a compressed air dryer or downstream of aftercoolers or air receivers.
