XRB Series Air Filtration Systems

A Donaldson XRB air filtration system is a complete air filter unit for construction machinery with high airflow capacity and Cycloflow airflow design, engineered for applications with high dust conditions and defined intake air filtration without separate pre-cleaner systems.

The XRB series belongs to complete air filters for construction machinery and is used as a closed system unit within the intake air system of off-highway machines.

System Classification

The XRB series is used when high dust conditions and high airflow demand occur simultaneously and stable intake air filtration must be ensured within a closed system.

Typical applications include construction machinery, mining equipment, recycling systems and other off-highway machines operating under consistently high particulate loads.

Unlike individual air filter elements, the XRB series represents a complete system consisting of housing, airflow routing and filtration.

Cycloflow Airflow Design and Filtration Behavior

The Donaldson XRB series uses Cycloflow airflow design to ensure stable airflow distribution within the system.

Unlike the FKB series, the XRB series is not primarily focused on centrifugal pre-separation, but on uniform airflow distribution at high volume flow rates. This allows consistent filtration even under high airflow conditions.

The defined airflow supports a uniform load distribution across the filter element and reduces localized stress peaks within the filter media. As a result, filtration performance remains stable even at high airflow volumes.

Filtration is performed entirely by the filter element. The system is therefore designed for high airflow capacity and even filter media utilization.

System selection is based on airflow, installation space, connection geometry and machine requirements.

Technical Features

  • High airflow capacity: designed for applications with large volume flow
  • Cycloflow airflow design: controlled airflow distribution within the housing
  • Compact system integration: closed design without separate pre-cleaner systems
  • Flexible installation: depending on configuration, horizontal or vertical mounting possible
  • Sealing concepts: series-dependent sealing systems (e.g. RadialSeal™) for defined sealing performance

Applications and Operating Conditions

XRB air filtration systems are used in applications where a combination of high airflow and high dust conditions is present.

Typical use cases include earthmoving, mining, recycling and construction site operations with continuously high particulate concentration.

The series is used when high-performance filtration is required without the use of separate external pre-cleaner systems.

System Comparison within the Donaldson Portfolio

The XRB series is positioned within the Donaldson air filtration systems in the segment of high airflow without separate pre-cleaning stages.

  • FKB series: Cycloflow systems for medium dust conditions
  • XRB series: systems for high airflow and high dust conditions
  • PSD series: systems with integrated pre-cleaning for extreme dust conditions

The XRB series is preferred when high airflow capacity is more critical than maximum pre-separation efficiency, while maintaining compact system integration.

Compared to the PSD series, the XRB series does not use a separate pre-cleaning stage and can therefore be integrated more easily into machine designs.

Position within Air Filtration Systems

The XRB series is part of filters for construction machinery and is used within construction machinery air filters in the complete air filters category.

It belongs to Donaldson air filtration systems and is used within these system series for applications with high airflow demand.

System Environment and Maintenance

The XRB series belongs to construction machinery air filters. For maintenance and service, suitable air filter elements must be selected based on series designation, housing configuration and reference number.

Identification Before Purchase

Before ordering, the series designation, reference number, machine model and installation conditions must be verified.

Check before purchase

  • XRB series designation
  • Reference number of the existing system
  • Machine model and series
  • Installation space and connection geometry

Technical Support

Selection of the correct XRB air filtration system is based on technical system identification and the specific operating requirements of the machine.
