Coolant filter for water jet cutting systems

Woven and magnetic

FILTERJET is a coolant filter specifically designed for the filtration of water used in water jet systems (water cutting) contaminated by abrasive and cut material. The purifier is manufactured in AISI 304 stainless steel. The degree of filtration that can be obtained is determined by various factors, including the type of filters used, the material processed, etc.
It is possible to reach a filtration degree up to 3μ with the complete series of filters.


Filterjet is produced in stainless steel, particularly suitable for the purification of water or corrosive or aggressive liquids.


The fabric filtration guarantees a very high degree
of purification. Different types of filter fabrics
are available.

LOSMA guarantees that every single unit is individually tested through strict control procedures.
Each unit is issued a test certificate for quality and function.

  • The coolant contaminated with impurities arriving by gravity from the water jet system is loaded on the DMD magnetic filter with self- cleaning drum, made of AISI 304 stainless steel (A) (if magnetic material is processed) or distributed by the trough on the fabric filter (B) (if non-magnetic material is processed).
    The filter fabric (C), duly chosen for its weight and degree of filtration, retains the polluting particles and allows the liquid to flow into the collecting tank below.

  • The tissue progressively accumulates polluting particles, increasing the degree of filtration until it becomes clogged. At this point, the liquid is no longer able to pass through the filter fabric, so it rises to level, lifting the float (D), which activates the microswitch and controls the advancement of the conveyor and the consequent replacement of the consumed fabric with the new one.

  • The consumed fabric (E) is collected in a special tank located at the head of the purifier, while the pre-filtered liquid collected in the tank below is sent, by means of the special electric pump (F) controlled by two electromechanical levels, to the 3μ superfiltration cartridge, which is also inserted in an AISI 304 stainless steel tank and from which the superfiltered liquid is discharged by gravity.

  • 3 micron superfiltration cartridge. The superfiltration cartridge (G) is fed by a pump whose start and stop is controlled by two independent electromechanical levels. The hydraulic connection unit, equipped with a pressure switch, gives indication of cartridge clogging/replacement.

Electrical equipment
The system can be supplied with:
• Electrical panel for complete system management
• Terminal box with all components wired (it must then be completed with electrical panel or interfaced to the machine tool)

4. Stainless STEEL transfer tank (optional)

Allows the superfiltered liquid to be collected at 3μ and then transferred for disposal, by means of an electro-level pump, even at long distances.

5. 3 micron superfiltration

The 3μ superfiltration cartridge inserted in a special AISI 304 stainless
steel sheet tank complete with gravity outlet. It can be connected to an additional transfer station (for very distant
drains), or directly to the disposal manifold.
