Air Filter Accessories for Construction Equipment

Function within the Intake System

Air filter accessories are part of the complete intake path between air intake and engine. They directly influence:

• pre-separation of dust and water
• airflow and flow behavior
• load on the main filter
• monitoring of filter condition

System design is always based on the complete intake configuration, not on individual components.

Components and Technical Function

• Pre-cleaners (cyclones): separation of dust and water via centrifugal force to reduce load on downstream filters
• Rain caps: protection of open air intakes against water and contamination
• Service indicators / service switches: monitoring of differential pressure to determine filter condition
• Mounting brackets for air filters: secure installation of air filter housings using clamps or bolted connections
• Air ducting components: connection of intake, pre-cleaner, filter housing and engine

These components complement complete air filter systems as well as air filter elements.

Pre-cleaners and Service Life Extension

Cyclone pre-cleaners significantly reduce the dust load on the main filter. Pre-separation increases filter service life and reduces contamination of the intake system.

The use is critical in dust-intensive applications.

Filter Condition Monitoring

Service indicators measure differential pressure within the air filtration system and indicate the actual load condition of the filter element.

Missing or incorrect monitoring results in delayed filter replacement or unnecessary maintenance.

Airflow and System Integration

Air ducting components connect all elements of the intake system. Deviations in geometry or cross-section lead to pressure losses or altered airflow behavior.

Matching airflow requirements and installation conditions is essential for proper system performance.

Applications

• construction equipment and off-highway machines
• agricultural machinery
• stationary aggregates and industrial systems
• intake systems exposed to high dust or moisture

Position within Air Filtration Systems

Air filter accessories complement existing filtration systems and are not standalone filters.

Compared to wet air filters, oil bath air filters or breather filters, they provide supporting functions within the intake system.

Selection Criteria

• system configuration and airflow requirements
• connection type and geometry
• installation conditions
• reference or existing system

Incorrect selection leads to installation issues or reduced system performance.
