The Gaparator ERS range of external rotary screens operates with a pumped or gravity feed entering the inlet launder that is designed to reduce the flow velocity and ensure a uniform and controlled distribution of liquids and suspended solids. This is presented to a circumferentially wound external wedge wire drum and dewatering takes place immediately on contact with the carefully selected slot-gap screen cylinder.

Suspended solids on rotation are efficiently removed by a spring-loaded doctor blade whilst the screened liquid passes through the cylinder and performs a systematic backwash of the screen opening on its exit to the outlet chamber.

An integral wash facility is provided to intermittently flush the screen providing maximum open area at all times affording high capacity throughputs with the ability to separate fine and hostile particles. Machine widths range from 300 to 3000mm.

On site demonstration facilities are available for the Gaparator ERS range with interchangeable wedge wire elements in a variety of slot gaps to determine the ideal separation.
