Precoat Filter ASF

The Clear One

For ultra-fine and clear filtration of fluids
For highly demanding applications
For starting off where others stop

Precoat Filter ASF

HOFFMANN Precoat Filter ASF
are especially suited where other filter systems have reached their performance limits, such as in the machining of cast iron, hard metal or HSS.

Filter fineness from up to 3 µm
It is especially used for ultra-fine and clear filtration of oils, synthetic solutions, process water and other fluids where a clear filtrate down to nominally filter fineness 3 µm is always required.

Automation according to your requirements
In addition to their use in metal processing, the special fields of application also render HOFFMANN Precoat Filters ideal in the beverage and environmental industries, as single or central systems.

Generously dimensioned tanks
HOFFMANN precoat filters are equipped with generous tanks for the continuous care of the machine tool.

Reliable cooling in continuous operation
An integrated cooler in the clean tank brings the cooling lubricant to the required temperature for the machine tool. Additionally, separate cooling circuits are available for, for example, a spindle or motor cooler.
