SPIN-ON OIL FILTER 

Spin-on oil filters form one unit consisting of housing and filter element. The whole unit is replaced during maintenance.

The following can be integrated:

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 and fit a spin-on oil filter quickly and efficiently.

OIL FILTER ELEMENTS  
The ECO-Friendly alternative

Standard Feature and benefits

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.

The MANN-FILTER EVOTOP® is particularly eco-friendly, as it is metal-free. It is made of one material and does not create any ash when disposed of in a thermal process.

Benefits of EVOTOP :

• reduced use of raw materials
• kinder to the environment with less waste during maintenance waste disposal problems are eased

Version of oil filter elements:

• element with foil end caps
• element with plastic end caps
• element with plastic end caps and plastic centre tube

AIR FILTER ELEMENTS  
innovative filter designs

Far-reaching development in electronics and extensive technology to meet increasing safety and comfort requirements, as well as developments in engine design have resulted in a constant reduction in space for installation. This means less space for air filters. Modern air filter systems must therefore adapt to new circumstances.

MANN-FILTER is developing innovative air filters which fit the installation location exactly in form and function. Air filters do not always need to be rectangular.

Where the installation conditions make it necessary, alternative shapes are available (trapezium, oval-conical filters etc). An example for optimum use of installation space is the MANN-FILTER air filter with stepped bellows. The stepped arrangement increases the filter surface considerably and improves the filter capacity. The air filter with a hole for bracing a hood and housing also demonstrates MANN+HUMMEL's ingenious techniques: There are two air filter elements in each vehicle. The fixing mandrel for the cover hood goes through the element.

MANN-FILTER offers a huge range of products, with hundreds of shapes and sizes. All of them are of the same high quality.

SECONDARY ELEMENTS  
optimum engine reliability

The high-quality MANN-FILTER secondary elements for air filters offer all-round protection from wear. This is even maintained when the main filter element is damaged or not effective due to a maintenance error. The additional protection is required particularly under extremely dusty conditions.

MANN-FILTER secondary elements are therefore included as standard in many agricultural machines and construction vehicles.

In the field of safety, brakes are amongst the most important components of a vehicle and dry, clean air is particularly important for the pneumatic braking systems on trucks and buses in order to protect the system from corrosion and malfunctions. The MANN-FILTER air dryer cartridge solves this problem. These boxes guarantee the best possible protection for the brakes on account of their excellent function and quality.

The advantages of the MANN-FILTER air dryer cartridge speak for themselves:

• highest possible resistance to pressure and pulsation
• highest possible rigidity to vibration
• premium quality desiccant with the highest possible drying performance, abrasion resistance, and water-resistance
• improved oil separation
• highest possible quality of sealing material
• great corrosion protection
• best possible braking reliability.

To prevent the engine from getting too hot the cooling water has the job of conducting away the heat generated by its operation, both in conditions of extreme winter cold and in the full heat of summer.

If the cooling system is to work reliably the fine channels in the engine block must be kept free of any accumulation of contaminant. This is where MANN-FILTER cooling water filters show their capability. They filter the suspended particles out so that only clean cooling water flows through the capillaries in the engine. This guarantees the best cooling of the engine.

Standard Feature and benefits

High-performance, state-of-the-art technology is now used for fuel-injection systems in diesel-powered vehicles. This means that the requirements relating to diesel filtration have increased substantially. Both ultrafine particles and large quantities of water must be separated efficiently from the fuel.

The advantages of the PreLine® pre-filter system are:

• stable, perfect water separation
• high function integration
• high dynamic rigidity
• efficient heating in the feed tube

Engine speed is converted into road speed in a controlled way by the transmission. As modern transmissions are required to process greater torque, operate smoothly and function more reliably, they are more demanding with regard to oil purity. Transmission fluid filters must therefore meet  exacting standards. MANN-FILTER transmission filters offer individual state-of-the-art solutions to meet the complex requirements of widely differing transmission concepts.

Basically, two types of transmission oil filters are available - suction and pressure filters.

Suction filters are used in automatic transmissions, and are fitted as compact flatbed filters located in the sump of the transmission. The oil is sucked through the filter by the oil pump being cleansed during this process. MANN-FILTER transmission filters offer optimum protection against engine wear by employing modern, efficient filter media in a compact design. Adapted to meet the specific requirements, taking into account for example installation space, oil purity and low differential pressures, the optimum filter medium is selected, in filter bag or pleated form.

Pressure filters are used to complement suction filters in innovative concepts such as CVT or twin-clutch gearboxes and in manual transmissions where a higher standard of oil purity is required. MANN-FILTER transmission oil filters contain innovative, very fine filter media which provides optimum oil purity and thus maximum protection against wear of the sensitive gearbox components. MANN-FILTER transmission filters for use on the pressurised side of the oil circuit are available as filter elements or as spin-on filters which are screwed on to the transmission.

Standard Feature and benefits

Some of the soot particles formed as a by-product of combustion get past the piston rings and penetrate into the crankcase, where they are absorbed into the lubricating oil. Modern lubricating oils contain additives which retain the soot particles in suspension, thus preventing sludge formation in the engine. However, as the concentration of soot increases, the oil becomes more viscous, which reduces its lubricating capacity. Furthermore, the soot particles essentially consist of carbon – they are therefore very hard and accelerate wear considerably. As a result, to minimise engine wear, the concentration of soot particles in the lubricating oil must be kept as low as possible.

Full-flow filtration cannot be carried out, due on the one hand to the risk of blocking of the filter, and on the other hand due to the impractical effort of filtering out the small soot particles (1 µm). The solution lies in the bypass filtration process, in which a portion of the lubricating oil is filtered separately to a high standard. One of the most effective processes in bypass filtration is to clean the oil through centrifuging.

• Flow rates
  Air Oil Separator Boxes are available for nomi-
  nal 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).
  
• Pressure drop
  The pressure drop at nominal flow rate and at 7 bar (0.7 MPa) operating pressure is approx. 0.25 bar (25 KPa) with a new element.
  
• Pressure resistance
  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) (please see table on page 13). The built-in filter elements can withstand pres-
  sure differences min. 5 bar (0.5 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.
  

Standard Feature and benefits

• Separation efficiency
  The residual oil content at nominal flow rate and at 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
  Standard Wrap Elements are available in a variety of sizes. They will only function properly when there is no leakage between the wet and the dry sides. Air should be guided in such a way as to prevent the air oil stream impacting
  directly on the surface of the filter element.
• Design and function
  This product is suitable for flow from the outsi de 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.
• Pressure drop
  The pressure drop at nominal flow rate and at 7 bar (0.7 MPa) operating pressure with a new element is 0.17 bar (17 KPa). If a higher resistance is permitted, the volumetric flow
  rate can be doubled without downgrading per formance.
• Pressure resistance
  Air Oil Separators are designed for differential pressures of and upwards 5 bar (0.5 MPa).
