MANN+HUMMEL Air Filter Systems for Construction Machinery
An air filter system is a complete filtration unit for construction machinery that cleans intake air in multiple stages and consists of pre-separation and main filtration.
MANN+HUMMEL air filter systems are used in excavators, wheel loaders and other off-highway machines and are part of the construction machinery air filters category. They protect engines from dust, particles and contaminants in the intake air.
Unlike individual air filter elements, these systems integrate multiple filtration stages into a single unit and handle the complete air preparation within the intake system.

Function within the intake system
Air filter systems clean the incoming air before it enters the engine. Coarse particles are removed in the pre-separation stage, while the main filter element performs fine filtration.
Insufficient air filtration leads to increased wear on the engine, turbocharger and intake system.
System series overview
MANN+HUMMEL air filter systems are available in different series, which vary in design, airflow capacity and application range:
Selection is always system-based and depends on airflow, installation space and dust load, not solely on external dimensions.
System design and filtration principle
Multi-stage air filter systems combine pre-separation and main filtration. In the first stage, particles are removed by cyclones or pre-cleaners. The filter element then performs fine filtration.
This design reduces the load on the filter element and extends service life compared to single-stage systems.
Applications and use cases
Air filter systems are used in construction machinery and off-highway applications, including:
- Excavators
- Wheel loaders
- Dozers
- Agricultural and forestry machines
- Stationary equipment
Typical operating conditions include high dust exposure, variable airflow and limited installation space.
Technical selection and identification
The correct air filter system is selected based on system series, reference number and machine application.
- System series (e.g. EUROPICLON, IQORON)
- Reference number
- Machine model
- Airflow capacity
- Installation configuration
An incorrect air filter system can lead to increased engine wear and reduced service intervals.
Position within the filtration system
Air filter systems are clearly distinguished from air filter elements, which are individual components used within a system.
Additional components in the air filtration environment include pre-cleaners (cyclones) and air intake components, each fulfilling specific functions within the intake system.
Air filter systems therefore represent the central unit for air treatment within the intake system of construction machinery.
