Automatic self-cleaning filters

Rotor filter sel cleaning ROTO-CLEAN R-BP-S2x

Rotor filter self cleaning screen filters are designed for filtration of
liquids with solid particles and colloidal materials. Special suction
pads ensure the complete cleaning of the screen with minimum
water consumption and without stopping the filtration process.
Rotor filter filters are completely made of stainless steel and this
gives them exceptional resistance to wear and corrosion. They can
be supplied in three different configurations (Y, L, and O) depending on the position of In/Out connections. The filtering cartridge can be supplied either as a polyester mesh inserted between two AISI 316 net tubes or as a three layer AISI 316 stainless steel cartridge (REPS); with this solution the filtration degree ranges from 25 μm to 810 μm. All filters are supplied ready to work, with valves, pressure gauges and electronic controller included.

FILTRATION
Dirty water flows in to the filter through the inlet port (IN) across
the filtering element (1) who retains the suspended solids inside;
clean water exits from the output port (OUT).

CLEANING
The cleaning of the filtration element can be performed by
preset time or when the progressive buildup of suspended solid
causes an excessive differential pressure between inlet and outlet
(0.8 bar). During the cleaning cycle the opening of the drain valve
and the engine rotation actuate the suction scanning system (2).
The perfect adherence of scanners to the internal surface of the
cartridge guarantees the aspiration of all the particles retained in
the filter. Dirty water and solids are purged through the drain port
(DRAIN).
