WORK
Water enters the filter through the inlet and goes through the pre-filtering cylinder from the
outside to the inside, after the water goes to the filtering cylinder from the inside to the
outside.This will retain all non-deformable suspended solids that are the same size or bigger than
the filtration degree installed. Filtered water leaves through the outlet pipe outlet.
REGENERATION
The continuous settling of suspended solids inside the filtering cylinder obstructs the passage
of water which results in a pressure difference (ΔP). At a preset value of ΔP (range 0.3 ÷ 1 Bar) an
automatic cycle will start to clean the filter cylinder. This operation begins with a signal that
opens the discharge valve and creates communication between the suction nozzles with the
outside environment. At the same time, the electric motor creates a rotating motion which
enables the nozzles to inspect the filtering surface. Dirt is ejected through the discharge valve.
The cleaning cycle lasts approximately 15 seconds.
