REX® Standard Duty/FR

The REX® Standard Duty/FR (Front Return) Bar Screen is a self-contained chain and rake type screen. The screen can be supplied with either a fixed mounting, or it can be designed to pivot out of the channel. The debris is captured by the bar rack and removed by multiple rakes from the upstream side of the screen.

The Standard Duty/FR Bar Screen is designed to operate at regular 24-hour intervals. A start timer will initiate the cleaning cycle to remove the collected debris from the bar rack. The unit will cycle until two or more rakes have passed the stop limit switch at which time the unit will shut down until the off timer initiates another cycle. The off timer is adjustable to suit each application.

A float switch or differential control can be provided to override the timer and initiate a cleaning cycle. The screen can be mounted in recesses in the channel walls or mounted to the channel walls.
