JWC Environmental's Bar Screen Monster is a self-contained reciprocating rake bar screen designed to capture and transport large amounts of wastewater debris to the discharge point. It uses a fully submersible, explosion-proof brake motor to drive the rake along the tracking system. The unit consists of a non-lube pin rack and tracking system. It accommodates widths from 2.5 feet to 6 feet and depths up to 12 feet. The rake speed operates at a minimum 20 feet per minute, the company says.
