With more than 6,000 references and recognized as the most efficient headwork screen, the ANDRITZ SEPARATION Aqua-Guard fine screen is the most reliable screen you can find. Using the functional principle of a moving/lifting staircase, the Aqua-Guard fine screen allows, as the flow passes through the screen, to replace separated elements by using exchangeable and proven ABS teeth. This unique system of retractable teeth allows the Aqua-Guard fine screen to be self-cleaning (at the top of the machine). To eliminate the sticky and fine particles from the screen, a system of rotating brush comes to increase the cleaning performance. Its bi-dimensional mesh system makes it ideal for any installation of screening. Hence, our Aqua-Guard fine screen is one of the most reliable and proven equipment (lifespan up to 20 years).
