High-performance filters for modern process systems.  Cartridge filter housing.

MAHLE can call on a long history of experience in the production of high-quality filters and cartridges for hydraulic filtration. This knowhow is also leveraged for other applications, such as the filtration of washing fluids for cleaning components. Increasingly strict requirements are specified regarding the cleanliness of industrial parts - and thus the washing fluids. The filters and filter materials are suitable for all popular washing media used to clean components.

These filter housings are manufactured completely from stainless steel and installed in a wide variety of process filtration systems.





  • Low space requirement thanks to compact construction








  • Minimal pressure loss due to flow optimized design of components








  • Visual/electrical/digital maintenance indicator








  • DIN flanges








  • Easy adaptation to higher dirt load by fitting a taller top housing part and longer cartridge - with no need to convert the system

    Technical data is subject to change without notice!

    The switching function can be changed by turning the electric upperpart by 180° (normally closed contact or normally open contact). The state on delivery is a normally closed contact. By inductivity in the direct current circuit the use of suitable protection circuit should be considered. Further maintenance indicator details and designs are available in the maintenance indicator data sheet. Further indicator details about digital maintenance indicator are available in the maintenance indicator data sheet or manual instruction PiS 3160.

    We draw attention to the fact that all values indicated are average values and do not always occur in specific cases of application. Our products are continually being further developed. Values, dimensions and weights can change as a result of this. Our specialized department will be pleased to offer you advice.

    We recommend you to contact us concerning applications of our filters in areas governed by the EU Directive 94/9 EC (ATEX 95). The standard version can be used for liquids based on mineral oil (corresponding to the fluids in Group 2 of Directive 97/23 EC Article 9).If you consider to use other fluids please contact us for additional support.

    The filter housings (pressure equipment) in standard design according pressure equipment directive 97/23/EG are applicable for
    a) fluids whose vapor pressure comes up to max. 0.5 bar above the standard atmospheric pressure (1013 mbar) at the permissible temperature (art. 3/1.1/b).
    b) fluids of liquid group 2 (art.9) with max. 90 °C. Filter design and production is made according pressure equipment directive 97/23/EG art. 3, paragraph
    3. For this kind of filter housings, no CE-conformity declaration according to 97/23/EG can be issued.

    The standard design can be used for all current cleaning fluids in the process technology. This contains the most hydrous, neutral, basic, acid and hydrocarbon cleaners. With amine-containing cleaners, the exact operating conditions (concentration as well as temperature) have to be clarified in advance. Other applications and media only available on request and if necessary after laboratory investigation.

    10. Installation, operating and maintenance instructions
    10.1 Filter installation
    When installing the filter make sure that sufficient space is available to remove filter element and filter housing. The maintenance indicator must be visible.
    10.2 Connecting the electrical maintenance indicator
    1. The electrical indicator is connected via a 2-pole appliance plug according to DlN EN 175301-803 with poles marked 1 and 2. The electrical section can be inverted to change from normally open position to normally closed position or vice versa (see data sheet PiS 3192/2.2).

    2. Filter with a digital differential gauge and analog signal outlet, can be integrated into an existing system control. The programming of the PiS 3160 has to be made according to parameter sheet enclosed, in order to ensure an element replacement at 2.2 bar(see data sheet/manual instruction PiS 3160).

    10.3 When should the filter element be replaced?
    1. Filters equipped with visual and electrical maintenance indicator:
    During cold starts, the indicator may give a warning signal. Press the red button of the visual indicator once again only after operating temperature has been reached. lf the red button immediately pops up again and/or the electrical signal has not switched off after reaching operating temperature, the filter element must be replaced.
    2. Filter with a digital differential gauge, analogue signal outlet and switch contact:
    The signal for element replacement can be displayed via the switch contact or the analog signal output and a system control unit.
    3. Filters without maintenance indicator:
    The filter element should be replaced when a differential pressure of 2.2 bar is reached. Afterwards follow instructions of the manufacturer.
    4. Please always ensure that you have original MAHLE spare elements in stock: Disposable elements (Sm-x) cannot be cleaned.
    10.4 Element replacement
    1. Stop system and relieve filter from pressure.
    2 . Discharge the filter housing completely.
    3 . Open clamps or black flange screws.
    4 . Remove cover carefully.
    5 . With filter housings with more cartridge configuration, loose and remove the elements’ holding plate/fixing.
    6 . Pull the filter element out of its spigot by turning and light listing.
    7 . Make sure that the order number on the spare element corresponds to the order number of the filter name-plate.
    8 . For insertion of the new elements, lightly bathe the o-rings with the medium to be filtered.
    9 . Attach and fix the elements’ holding plate/fixing.
    10 . Check O-ring on the filter housing for damage. Replace, if necessary.
    11 . Attach the cover carefully and close with the clamp or with black flange tighten the screws.
    12 . Close the drain plug and vent the filter completely.
    13 . After venting, check the housing on leak tightness.
