Volvo Engine Filter Categories







Filtration categories


Air filters are usually divided into three filtration categories. The choice of filter type depends on the area of application, dust concentrations where it will operate and required service life. The three filtration categories are shown below together with information about their use. Note that these guidelines are only recommendations and that it may be necessary in certain situations to use a filter suited to conditions dustier than those specified.




Air filter for minor dust quantities (dust concentration 15 mg/m3)


Usually installed directly on the inlet manifold and generally without a pre-cleaner.


Used in: a highway vehicle applications in countries with temperate climates, i.e. where dust concentrations are low. b industrial installations for driving in sheltered conditions and in areas with low dust concentrations.








Typical air filters in this category are dry filters (paper elements) without pre-cleaners and with only moderate dust collection capacity.




Air filter for medium dust quantities (dust concentration 520 mg/m3)


Usually installed directly on or a little way away from the engine; generally has an internal or external precleaner. Used in:


a highway and terrain vehicle applications in countries with temperate climates and drier climates, i.e. where dust concentrations are moderate.


b general industrial applications.


c all normal agricultural applications.




Typical air filters in this category are dry filters with integral centrifugal pre-cleaners with greater dust collection capacity than air filters for low dust quantities described above.




Air filter for large dust quantities (dust concentration 20100 mg/m3)


This filtration category usually includes high-efficiency pre-cleaner devices which in some cases are emptied of dust automatically.




Used in:


a terrain vehicle applications where dust concentrations


are extreme, e.g. in quarries, ground preparation etc.


b earth graders, industrial equipment, stone


crushers and chippers.


c agricultural equipment designed for operations in extremely dusty conditions.






If a customer requires a special air filter that is not included in the Volvo Penta Sales Support Tool,


Partner Network the customer is entirely responsible for correct layout and installation. If the Volvo engine is damaged due to mistakes in the layout or installation of the air cleaner system, Volvo Penta will deny any claims made against the engine warranty.




Inlet pipe, after filter


Inlet system pipes and their associated attachments must be checked thoroughly in order to minimize flow restrictions and to ensure that seals remain reliable throughout the operational conditions the engine is exposed to during use.




NOTICE! It is absolutely essential that all pipes are thoroughly cleaned and have their internal surfaces correctly treated to prevent rust particles and foreign materials from welding entering the engine. The surface must be dip painted, zinc dipped or galvanized. In order to minimize flow restrictions in the system, the pipes must be as short and have as few bends as possible.


NOTICE! No pipe cross-sectional areas may be smaller than the cross-sectional area of the inlet manifold opening.




Fixed pipes


The pipes may be of steel, aluminum or molded plastic but the internal surfaces must under all circumstances be smooth and free from defects. Pipe ends used together with hose connectors must be perfectly round and have an even surface along at least 50 mm (2") of pipe at every connection. Pipe walls must be thick enough not to be deformed by the pressure from hose clamps. All pipes must ideally have end flanges to improve sealing and allow hoses to be fastened more securely.










Smooth, i.e. unreinforced hose sections may only be used to join parts of fixed pipes etc. that are located in line and
