BOLLFILTER Simplex
TYPE 1.12.2

Application
Filtration of all liquids. For installation

with flanged connections DN 25 – DN 80
optionally with integrated steam heating

into suction or pressure pipework
to protect downstream equipment
(pum­ s, bearings, heat exchangers,
p
valves, pipework etc.) against contamination or accumulation of mud.

Operation
The filter is completely maintenancefree except for checking of the seals
and cleaning of filter elements. The
pressure drop indicates the contamination degree of the filter. To clean the
filter element, the installation must be
shut-down or the filter isolated.

Cleaning
Depressurize the filter chamber by
means of the venting screw. Lift the
housing cover, remove the filter element, rinse it with the cleaning fluid,
e.g. BOLL-CLEAN 2000, and clean it by
compressed air.
(See operating instructions ‘filter element cleaning‘).
