Cabin Filter Airflow Direction and Layer Orientation
Installation Procedure · Air Intake & Airflow Protection Systems
Technology: MICROKAPPA™
Engineering Relationships
- Layered cabin-filter media can be designed for a specific airflow direction, so installation orientation is a functional requirement rather than a cosmetic choice.
Components
- Cabin Air Filter
- Activated Carbon Media
- HVAC System
Problems
- Incorrect cabin-filter orientation
Diagnostic Methods
- Identify the HVAC airflow direction and the orientation marking on the replacement element before installation
Maintenance Procedures
- Determine airflow direction through the cabin-filter housing.
- Orient the filter according to the airflow indicator or vehicle-specific installation requirement.
- Verify the element is seated correctly and does not distort the housing seal.
Service Procedure
- Determine airflow direction through the cabin-filter housing.
- Orient the filter according to the airflow indicator or vehicle-specific installation requirement.
- Verify the element is seated correctly and does not distort the housing seal.
