MANN-FILTER W 712/4 – oil filter not only for vacuum pumps

The MANN-FILTER W712/4 oil filter is a robust spin-on filter designed for heavy-duty oil circuits.
Thanks to its stable construction, high-quality filter medium and resistance to high temperatures, this type is widely used in oil-lubricated rotary and vane pumps (e.g. Busch, Becker, Rietschle, Orion, Leybold – depending on specific compatibility)

The filter effectively captures

• carbon particles
• metal wear
• dust and micro-shavings
• vacuum oil residues after oxidation

This protects the pump from wear and increases the lifespan of the oil charge and the machine itself.
