Multi-layer filter type SF

The type SF multi-layer filter was developed to meet constantly rising demands for filter systems which require little in the way of filtration aids or even none at all. Their purpose is to filter cooling lubricants and any other low viscosity fluids, such as those typically used in the machining of tungsten carbide.

A type SF filter is capable of achieving the complete filtration of the fluid. In the field of ultra-fine filtration to particle sizes below 5 um, in particular, the systems which are normally available on the market (belt-type filters with filter cloths, laminated separators, centrifuges) have hitherto proved unsuccessful, since they are incapable of e.g. extracting particles in suspension in the fluid.

In certain ultra-fine machining processes, however, the fluid contains these very particles almost exclusively, in that the coarse particles which occur in other machining processes (and which are also capable of retaining smaller particles) are present to only a very limited extent in this case or are entirely absent.

In the field of sewage water filtration, the incipient limits can be significantly improved upon in this way, making expensive retreatment, in the form of flocculation or filtration with bag-type or cartridge filters, superfluous.
