MANN-FILTER W 940/5 – oil filter for vacuum pumps, compressors and industrial units

The W940/5 oil filter by MANN+HUMMEL is one of the most widely used spin-on filters in industrial applications.
It is ideal for vacuum pumps, compressors, hydraulic circuits and oil systems, where it is necessary to capture fine impurities, carbon, metal wear and oil deposit residues.

Thanks to its robust steel construction, high-quality sealing rubber and stable relief valve, it provides a long service life even at high temperatures and pressures.
The filter maintains stable oil pressure and protects equipment from premature wear.
