Bosch Filters

Bosch filters: Bodyguard for the engine

Bosch filters protect all the important and expensive components on and inside your vehicle. They are used to keep dirt, abrasion, fine particles – and water in the case of diesel engines – away from injection systems, engines, and occupants. What’s more, Bosch filters come in a comprehensive product range to suit nearly every car and commercial vehicle. This range is constantly being updated and extended, which means that when you opt for Bosch, the worldwide filter specialists, you will always have state-of-the-art filters

Consequences of silted-up filter:

• Loss of engine power, even to the extent of an engine standstill
• Impairment or interruption of the fuel supply
• Impairment to the output of the fuel pump, even to the extent of a short-circuit
• Increased wear
• Internal corrosion of engine components

Also ideal for biodiesel: Bosch diesel filters

Special features of biodiesel:

• Aggressive behavior against elastomers and sealing materials
• “Saponification” of the fuel through reactions with certain materials
• Lower water separation
• Faster silting up of the diesel filter
• Increased growth of microorganisms
• Thanks to resistant materials for the seal and housing, ideal filter media, and improved separation of water, diesel filters from Bosch are the optimal solution even when using biodiesel.

Consequences of silted-up filter:

• Loss of engine power
• Impairment or interruption of the fuel supply
• Impairments to the output of the fuel pump, even to the extent of a short-circuit
• Increased wear

Gasoline line filters for carburetor engine

Even the smallest particles can cause considerable wear on your vehicle’s injection system. To guarantee ideal operation and a long service life of the components, gasoline filters from Bosch filter out even the smallest impurities with a diameter of less than one thousandth of a millimeter.

Task of the oil filter

To protect the engine against impurities in the oil

Consequences of silted-up filter:

• Poor air-fuel mixture generation resulting in reduced engine power and increased pollutant emissions
• Increased fuel consumption
• Increased engine wear from particles
• Problems starting your vehicle

The prerequisite for flawless operation: Tight fit

Leakages and porosity lead to a bypass of unfiltered air (unmetered air) in the intake duct. Consequently, Bosch air filters possess a particularly long-lasting seal made of polyurethane:

Exact fit matched to the housing shapes

Unevenness in the housing is compensated

Flexibility and suppleness in the seal across the entire service life of the filter

Bosch activated carbon cabin filters

• Three fiber layers plus activated carbon layer
• Thanks to an electrostatic charge, the fiber layer of electrostatically charged micro-fibers attracts even the smallest, respirable particles and filters them out of the air
• Reliable function between -40 and +85 °C –
• Absorption of smells and harmful gases by the activated carbon layer

Bosch standard cabin filters

• Three coordinated fiber layers with different fiber sizes
• Thanks to an electrostatic charge, the middle fiber layer of electrostatically charged micro-fibers attracts even the smallest, respirable particles and filters them out of the air
• Reliable operation from -40 to +85 °C

Bosch commercial vehicle filters: The professionals’ choice

No Compromises When it Comes to Commercial Vehicles: Quality Filters from Bosch

A commercial vehicle makes money every day. An out-of-action vehicle costs around EUR 2,000-3,000 a day. Worse still is sudden engine damage with cooling system failure, resulting in the need for compensation for spoiled goods. That is why engines and injection systems need reliable protection – with quality filters from Bosch.
