Air Intake Components for Air Systems – Construction Machinery
Air intake components are connection elements within the intake system that guide airflow between the air inlet, air cleaner housing and engine. They directly affect airflow rate, pressure loss and the uniform distribution of air across the filtration system.
Incorrect diameter, angle, reduction or connection geometry leads to increased restriction, unstable airflow and installation issues within the intake system.

Function within the Intake System
Air intake components do not perform filtration but are essential for connecting individual sections of the intake system. They direct incoming air from the intake point through the defined intake path to the air cleaner housing and further to the engine.
A properly designed intake layout minimizes pressure drop, reduces turbulence and ensures consistent airflow across the air filtration system.
Component Types and System Elements
The components in this category cover typical requirements of intake system routing and connection.
- Pipes and straight tubes: linear connections for defined intake sections
- Elbows (45° / 90°): directional changes within limited installation space
- Reducers and transitions: adaptation between different diameters
- Flexible hoses and bellows: compensation for movement, installation tolerance and vibration
- Connectors and beaded adapters: defined transitions between intake components
Materials and Connection Geometry
Air intake components are manufactured in materials such as steel, rubber, TPE or silicone, depending on application requirements. Material selection affects rigidity, flexibility, vibration behavior and thermal resistance within the intake system.
Key selection criteria include inner or outer diameter, bend geometry, length and connection type between system components.
Applications
- Excavators and wheel loaders
- Dozers and off-highway machines
- Agricultural and forestry equipment
- Stationary engines and aggregates
Air intake components are used wherever intake systems must be adapted to machine layout, available installation space or existing air cleaner configurations.
Airflow, Reduction and Pressure Loss
Every bend, reduction or change in cross-section affects airflow within the intake system. Incorrectly selected components increase restriction, reduce airflow and may lead to uneven loading of the air filter.
This is particularly relevant for reducers, 45° and 90° elbows, as well as flexible connectors, which must match the system geometry and airflow requirements.
System Integration within Air Filter Components
Air intake components are part of the air filter accessories and are directly connected to complete air cleaner systems and the installed air filter elements.
Within the intake system, they are commonly used together with pre-cleaners (cyclones) and rain caps where additional protection or pre-separation is required.
Selection and Identification
Selection is based on reference number, component type, diameter, angle and installation conditions. Compatibility with the existing intake system is essential for correct airflow performance.
Components with similar appearance but different dimensions or geometry are a common source of misidentification.
Check Before Ordering
- Reference number
- Component type: pipe, elbow, reducer, flexible hose, connector
- Diameter and connection type
- Angle and length
- Installation position within the intake system
