Compressed Air Products

The MANN+HUMMEL Group was established in Ludwigsburg, in southwest Germany in 1941. The Division Automotive OE develops, produces, and markets MANN+HUMMEL filter and air intake systems and other components for the automotive industry. The motor spares trade is supplied with filter elements under the MANN-FILTER brand name in the same quality as that supplied to OEMs. For general engineering, process engineering and industrial manufacturing sectors the product range includes industrial filters, a series of products to reduce carbon emission levels in diesel engines, filter systems and complete lines as well as units for conveying, dosing and drying of free flowing plastics.

MANN+HUMMEL Oil Filter Back to top
Have question about this product?

Spin-on oil filters form one unit consisting of housing and filter element. The whole unit is replaced during maintenance. Oil filter prevents wear in the compressor and extends the economic life-time of the air-oil separator element.
Standard Features,
Anti-drain valve:
Ensures that the filter and oil channels do not empty when the engine is switched off and that oil is readily available when the engine is started.
Bypass valve:
Ensures that oil is available when the engine is cold started and when a service is long overdue, if the oil filter is very dirty.
Wrench removal tools:
Ensure that you can remove anad fit a spin-on oil filter quickly and efficiently.



MANN-FILTER oil filter elements are either situated in their own housing or they are integrated directly into the engine oil circulation system. They are particularly kind to the environment as only the filter element is replaced. Housing and valves remain on the engine block. The exact fit in the housing ensures that MANN-FILTER oil filter elements are completely leak-free.

•                   Reliable processes
•                   All components are designed to work with aggressive compressor oils.
•                   High-performance provides optimum wear protection thanks to high dust capacity.
•                   Clean oil benefits the service life of the air-oil separator.

Air/oil separators - for your compressed air system

MANN+HUMMEL designs air/oil separators for energy efficiency and low residual oil content. MANN+HUMMEL offers custom-made solutions for oil separation for applications in compressors and vacuum pumps. Efficient separation media ensure the lowest possible residual oil content and high energy efficiency through low pressure loss, which saves users a considerable amount of money. The MANN+HUMMEL product range is the worldwide benchmark for air/oil separation.

 Air-oil separator elements

Low residual oil content extends the service life of fine filters downstream. Minimum pressure losses guarantee energy efficiency and long service life.

 Advantages of MANN+HUMMEL Air-oil separators

  • High efficient
  • Longer service life and energy efficiency

  • Minimum pressure losses.

  • Effective, minimum residual oil content of only 1-2 ppm

  • Cost saving
  • Extends service life of downstream fine filters.

Standard Features

    • Flow rates
      Air Oil Separator Boxes are available for nominal flow rates of 1 m3/min up to 5.5 m3/min (35 to 194 cfm) at an operating pressure of 7 bar (0.7 MPa).

    • Lower Pressure drop

    • Pressure resistance

Air Oil Separators are designed for differential pressures of and upwards 5 bar (0.5 MPa). The housings of the Air Oil Separator Boxes are designed for operating pressures up to a maximum of 20 bar (2 MPa) or a maximum of 14 bar (1.4 MPa)

    • Separation efficiency

The residual oil content of the compressed air at nominal flow rate and 7 bar (0.7 MPa) operating pressure is approximately 1 to 3 mg/m3 (1 to 3 ppm).


    • Service life
      The rise in flow resistance and thus service life primarily depend on the cleanness of the oil and the quality of the air filter. A service life of several thousand hours can be achieved with a well-functioning system.

    • Fitting advice
      Air Oil Separator Boxes are fitted vertically by hand on the firmly installed filter head using a suitable adapter union. 
      MANN+HUMMEL recommends installation in a maintenance-friendly position.

    • Maintenance
      The air oil separator boxes must be replaced if the flow resistance reaches 1 bar (0.1 MPa). The box may only be replaced when the system is depressurised. A commercially available belt wrench is sufficient to remove the box. The box is fitted and tightened manually.

    • Design and function
      This product is suitable for flow from the outside to the inside. It can be used for the entire range of current versions of screw-type and sliding vane compressors.
      The standard wrap elements are particularly insensitive to design variations and achieve optimal results with regard to separation efficiency and service life.
