F76S Water Filters and
MV876B Automatic-Backwash Controls
APPLICATION
The F76S is a high flow capacity water filter used at point-of-
entry (POE) to remove sediment and debris from residential or
commercial water systems. Used as a prefilter, the F76S
protects elements of the water system, including specialized
treatment devices such as taste/odor or reverse osmosis
(R/O) or other common fixtures and appliances. The flow,
filtering capacity, and ease of cleaning make the F76S the
ideal filter for the most demanding applications.
The MV876 Automatic-Backwash Control is available as an
accessory. This control is fitted to the drain valve and is
programmed by the user to automatically perform the back-
wash function according to the desired interval.
