Cabin Air Filter Options
Standard
Standard efficiency cabin air filters are available for all Cat equipment models. Standard efficiency cabin air filters are recommended for normal duty filtration. Standard efficiency media is designed to prevent dirt, soot, sand, and other contaminates from entering the cab under normal operating conditions.High Efficiency
High efficiency cabin air filters are available for some Cat equipment models. High efficiency cabin air filters are recommended for extremely dusty environments. High efficiency cabin air filters have a higher initial and overall efficiency for improved performance. High efficiency cabin air filters have improved dirt holding capacity, which extends filter service life, depending on the operating conditions.Activated Carbon
Activated carbon cabin air filters are available for some Cat equipment models. These cabin air filters are recommended in situations where odor is a problem. Activated carbon cabin air filters absorb odors as well as capturing dust. Activated carbon cabin air filters must be replaced regularly for maximum odor reduction.Lower Restriction
Lower restriction cabin air filters are available for some Cat equipment models. Lower restriction cabin air filters are typically recommended in situations where there is poor cab air flow. Lower restriction cabin air filters allow for more air flow into the cab, but typically have a lower efficiency.Cabin Air Filter Servicing
The capacity and restriction of cabin air filters are carefully designed for the optimal cab air flow and cleanliness. Proper service and management of the cabin air filters protects the heating and cooling system from dirt and dust, increases filter life, improves efficiency, and reduces cost of servicing. Proper service and management of the cabin air filters also creates a cleaner and more comfortable working environment for the operator.
Use care when handling a new filter element during servicing. Keep the filter element clean and in the appropriate packaging until ready to install the filter into the housing. Keep the filter element exposure to open air to a minimum to limit introduction of dirt or element damage.
Inspect the new filter element prior to installation into the housing to ensure that the element is free from any damage. Ensure that the filter element is well seated and sealed against the housing.
Do not "tap" a filter element, such as on a hard surface, to remove the dust. Hitting the filter element on a surface to remove the dust can damage the filter element. Deeply embedded dirt cannot be removed by tapping the filter element. This process will also remove the dirt layer that increases the filter element efficiency.
Always change air filter elements based on the recommended service interval, not the appearance of the filter. Refer to the Operation and Maintenance Manual for the recommended maintenance intervals.
Changing the air filter element based on the recommended service intervals allows for optimal service life and efficiency. Changing the air filter element prior to the designed life increases service time and cost unnecessarily. Changing an air filter element late may cause damage to the cab heating and cooling system due to potential failure of the filter element.
