An Air Filter Service Indicator primarily focuses on measuring the pressure drop across the air filter. As the air filter accumulates dirt, dust, and other contaminants, the airflow resistance increases, resulting in an elevated pressure differential across the filter. The service indicator's sensor or measuring device continuously monitors this pressure difference.Attributes:• Helps to protect the engine from contaminants, such as dirt and debris• Provide real-time feedback on the condition of the air filterApplications:An Air Filter Service Indicator monitors the condition of the air filter and provides indications when the filter requires maintenance. It serves as a proactive maintenance tool by continuously assessing the level of filter contamination and providing timely feedback to the user.
