F74C Reverse Rinsing Filter;
MV876 Automatic-Backwash Controls
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. 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.
