The RSA flushing automation is used for the automatic initiation of backflushing for the maintenance of DRUFI and DRUFI max filters. The automation features easy operation and is simply installed on the filter in place of the backflush button. It allows for the setting of a flushing interval from 1 hour to 52 weeks. It is battery-powered. A DN 50 drainage connection is required.

The automation is controlled using buttons and a display. The display remains in standby mode most of the time to conserve battery life, and it lights up only when one of the buttons is pressed.
