Description of the Faivre 40 Filter on Stainless Steel Tank
The Faivre Series 40 filter is a compact drum filter mounted in a stainless steel tank.
Operating principle
-
The liquid to be filtered enters the rotating drum, which is covered with a fine stainless-steel mesh.
-
Particles larger than the mesh size are retained on the outside of the filtering surface.
-
The drum rotates slowly (around 17 rpm depending on the model) and carries impurities towards a cleaning ramp.
-
A backwash ramp with nozzles cleans the filter plates, removing impurities into a sludge channel.
-
The cleaned water passes through the mesh and is discharged to the filtered outlet.

-
Drive system: “Direct Drive” — drum directly coupled to the gear motor
-
Rinsing nozzles: typically 3, with optimized pressure to avoid damaging the mesh
-
Rinsing ramp: equipped with a pressure gauge connection for backwash monitoring
-
Removable cover: for maintenance access
-
Options: level sensor, timer, optional rinse pump, electrical control panel with safety shutdowns
Advantages & applications
-
Compact size: easy to install in restricted spaces
-
Robust stainless steel construction: corrosion resistance, long service life
-
Adjustable mesh size: adaptable to system requirements
-
Automatic backwash: reduces manual maintenance and water loss
Limitations & constraints
-
With excessive particle load (suspended solids), clogging may occur more often, requiring frequent rinsing
-
For very high turbidity or extremely fine particles (smaller than minimum mesh), efficiency decreases
-
Rinsing system must be properly dimensioned (pressure, flow) for efficient cleaning without mesh damage
-
Stainless steel type (304L vs 316L vs Duplex) must match the water type (fresh, brackish, chemical) to avoid corrosion
-
In case of power failure or motor breakdown, the filter may stop functioning, causing clogging risk
