Everfilt’s 94B-4L-Series Backwash Controls are stainless steel backwash control units, fitted with LCD screens.

The backwash control unit will initiate a backwash cycle after reaching a predetermined time or by receiving a signal from the pressure differential switch, indicating a dirty filter condition.The 94B-4L, 94B-8L, and 94B-12L controls are equipped with an LCD Display to monitor total number of backwashes, time remaining until the next backwash cycle and the number of backwash cycles that have been initiated by the pressure differential switch.
