The Enviro-Care Company SAVI Flo-Drum Screen with a 2 mm perforated opening has a proven capture rate of 86 percent as verified by UK-WIR testing in 2015. A triple-face seal is the first barrier to incoming solids in the flow. The labyrinth seal prevents even small solids and hair from bypassing the screen. As the drum rotates, solids are captured on the interior of the drum and collected by strategically placed scoops that deposit the solids into the conveyor trough, where they are moved to discharge. A brush and spray on the exterior of the drum keep even the smallest solids inside the perforated drum. 815/636-8306; www.enviro-care.com.
