Magnetic filtering cylinders MFW
Applications:
Magnetic filtering cylinders are designed for the automatic cleaning of coolants.
They are used in honing, grinding, deep-drilling machines and lathes, hardening plants, cleaning plants, etc., in which ferritic suspended materials are to be filtered out of the coolant.
Function:
The contaminated coolant is introduced via one or several inlet connections into the pre-flooding chamber, where it is distributed over the entire cylinder width. After discharging from the pre-flooding chamber, the contaminated medium flows into an annular chamber segment around the magnetised pole plates of the filtering cylinder, whereby the ferritic suspended particles are separated from the medium. The cleaned medium discharges at the bottom of the housing and flows into a clean container below. The dirt particles adhering to the magnetic cylinder are removed from the medium by continuous rotation of the cylinder, scraped off with a scraper, and through the continuous accumulation of dirt, pushed towards the draining edge, from where they fall into a sludge box below.
Design:
Sturdy, wear-resistant metal housing Large capacity pre-flooding chamber Optimised magnet system High-quality permanent magnets Scraper made of high-quality steel 1.4301 |

Fully automatic filter FA
Applications:
Fully automatic filters are designed for the automatic cleaning of coolants in honing machines, grinding machines, metalworking lathes, milling machines, machining centers, hardening plants and washing plants, etc...
Function:
The contaminated lubricant is introduced via an inlet distributor on to a filter cloth arranged in a tank. The coolant runs through the cloth through gravity into the liquid tank arranged below the band filter. The dirt particles in the coolant are filtered out by the filter cloth, which results in an sludge cake formation. This causes a reduction of the permeability of the filter paper and so an increase of the liquid level above the filter tank. An adjustable float switch controls the electric motor-driven further transport of the filter cloth with in increasing liquid level.
The dirty filter cloth is therefore automatically discharged, depending on the quantity and impermeability of the contaminants. The contaminated filter cloth is introduced into a sludge box at the end of the fully automatic filter and can be removed without interruption of the filtering process. By the provision of an upstream magnetic filtering cylinder, ferritic dirt particles can be separated on the band filter prior to the introduction of the liquid, which can contribute to considerably reducing paper consumption.

Drum filter IBF
Applications:
This filter type can be used in all machining processes, where small chips and fine particles from liquids, also with higher viscosity, are to be filtered out. Except for machining centres, this filter type has proved suitable for use at grinding machines, honing machines and in washing water treatment systems. In addition to use as an individual system, this filter can also be used for the central supply of several machines.
Function:
Two disk wheels form the counter-bearing for the rotating supporting belt. Between these, the filter cloth is drawn in by an electric motor. The filter cloth thus forms a circular filter tank that is tight on both sides. The coolant feed takes place calmed via a flat distributor. The entering liquid flows in the direction of filter cloth transport and ensures that the cloth is kept clean in the inlet area in addition to maximum permeability. In the calmed liquid zone, the particles to be filtered settle and form a filter cake, which to an increasing degree, acts as a filter aid and also retains very small particles. After saturation of the filter cloth, the liquid level in the filter tank increases. When the maximum liquid level is reached, the level switch switches on the geared motor. New filter cloth is automatically drawn in, while the cloth loaded with sludge is discharged on the opposite side.

Vacuum filter VMF
Applications:
Continuous cleaning of contaminated coolants as they
occur when using machine tools.
Cleaning of liquids from industrial cleaning plants and
dedusting systems.
Recommended for use with high flow rates; the flow rate
is increased three to four times with the same filter area
and low filter medium consumption compared with a
gravity filter.
Function:
The contaminated coolant flows from the machine tool into the contaminant part of the filter. A vacuum pump draws the coolant through the filter medium into a clean chamber, whereby the dirt particles are retained by the filter medium. The dirt cake forming on the filter medium produces an increasing partial vacuum in the clean chamber. When a preset value is reached, regeneration is initiated by means of a contact pressure gauge; the dirt cake is discharged without interruption of the coolant feed and new filter medium is simultaneously drawn in.
Design:
Sturdy coolant-tight metal housing Full flow filtration Inlet distributor for air separation Intermediate bottom of perforated plate Minimum and maximum level indicator Integrated clean tank Worm-gear motor as the drive Drive station in discharge area Winding device for filter medium
