4. – DESCRIPTION OF FILTER FMA-3000
The filter consists of an outer casing which houses three distinct chambers. The first one is a
prefiltering chamber which coincides with the filter water inlet, and where the Coarse Mesh is
located, the second one is a FILTERING CHAMBER where the fine mesh is located and where
the filtering process takes place and the third one, which is a cleaning chamber.
In this case the water flows outwards from inside the filtering body. Suspended solids (dirt) are
retained in the filtering element, ie in the mesh. This chamber coincides with the filtered water
outlet to the desired application: drinking water, process water, cooling water, etc.
The dirt retained gradually forms a cake on the mesh, which generates a given pressure drop.
Cleaning the filter is supported by a second chamber, the CLEANING chamber, whose outlet is
connected to the DRAIN VALVE allowing evacuation of the wash water when generating the
SELF-CLEANING process. The cleaning chamber is separated from the filtration chamber by
means of a special seal.
Finally, the SUCTION SCANNER is a vital element of this technology. This scanner occupies the
exact position that the central axis of the filtering cartridge would occupy, and is hydraulically
connected to the cleaning chamber. In turn, the SUCTION NOZZLES are arranged
perpendicularly in the zone that it occupies in the filtration chamber, with the nylon bristles
