2 Application areas for MANN+HUMML fuel filters Te rapid development of diesel tecnology as made te filtration of diesel fuel before it reaces te injection system a top priority. Badly filtered diesel causes particle erosion, corrosion, and can lead to damage in te injection system. Te contamination of fuel wit particles and water occurs during production, transportation, in storage, wen te fuel is delivered, and wen te tank is filled. Tis contamination as to be removed in a reliable way. Te MANN+HUMML product range as te rigt filter for all types of injection systems. We recommend te MANN+HUMML PreLine (see page 8) as a preliminary fuel filter to pre-separate water and coarse particles.

3 MANN+HUMML Fuel filter media Modern diesel and petrol injection systems require te igest fuel quality and terefore set ever iger standards for te filtration of fuel. Te newly patented MANN+HUMML multigrade media were developed for diesel and petrol engines and meet today's igest requirements for fuel filter elements. Multilayer tecnology ensures tat sensitive injection systems are protected from even te finest particles. In comparison to oter media available on te market te multigrade media offers a performance increase in dirt olding capacity of up to 00% wit te same ig initial separation efficiency. Te family of multigrade media represents an important milestone in te field of fuel filtration. Tese media are used in all our ig performance filters. On page of tis catalogue you will find MANN+HUMML spin-on filters wit te multigrade media HC (ig capacity wit water separation), H (ig filter fineness) and H+ (igest filter fineness). Tis range economically covers all te requirements of modern fuel filtration. Te MANN+HUMML multigrade media guarantee te protection necessary for te sensitive injection systems of today. MANN+HUMML multigrade media: xtended service life and ig initial separation efficiency are acieved troug an open layer wit ig dirt olding capacity on te in-flow side and a fine filter layer on te out-flow side. 6

4 MANN+HUMML Spin-on fuel filters MANN+HUMML spin-on filters are used for te filtration of fuel in a number of applications. MANN+HUMML as been a leading manufacturer of spin-on filters worldwide for many years. Te filters are distributed under te MANN-FILTR brand and under a variety of customer brands. Te advantages at a glance: Available wit a range of filter media fficient separation and ig dirt olding capacity wit low pressure drop Robust, anti-corrosion ousing wit ig pulsation and pressure stability Geometry designed for optimum flow Undetacable seals Stable, non-collapsible central tube Non-return valve wit low pressure drop Design Te spin-on filter consists of a robust metal ousing wit te fitted filter element. Depending on te application, te spin-on filter can be equipped wit various components suc as a different filter medium, non-return valve or bypass valve, etc.. Te liquid to be filtered enters te cover plate troug te concentric inlet openings, flows troug te filter element and te cleaned liquid ten leaves troug te central connection. Te filter cover plate as an undetacable seal wic ensures secure sealing to te outside under all operating conditions. Maintenance Te time for maintenance is usually defined by te engine or macine manufacturer. Maintenance simply requires replacement of te complete spin-on filter. Te spin-on filter can easily be removed using a MANN+HUMML filter wrenc (see page 05). Seal Central tube Cross-section picture Filter ousing Filter element 68
