MV876 Automatic-Backwash Controls
F74C

APPLICATION

'The F74C Reverse Rinsing Water Filters, used at
point-of-entry (POE) to remove sediment and debris from
residential or commercial water systems, ensure a continuous
supply of filtered water. The fine filter prevents the ingress of
foreign bodies, such as rust particles and grains of sand. Both
horizontal and vertical installations are possible. The flow,
filtering capacity and ease of cleaning make the F74C the
ideal filter for the most demanding applications. Both
horizontal and vertical installations are possible.
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
backwash function according to the desired interval.
