A charcoal air filter is now available for the operator's compartment. The new 139-3204 Air Filter is interchangeable with the standard 105-4968 Air Filter.

The new charcoal air filter drastically reduces odors from the outside air. The charcoal air filter can be used in any application where cab odor reduction is an issue. The cleanability of the new charcoal air filter has also been improved to extend the useful life of the filter and minimize airflow reduction.

The filter should be replaced when the odor reduction capabilities are diminished or the filter has been damaged. At this time, the filter is only available through the Morton parts system.

NOTE: The 139-3204 Air Filter is for odor reduction only, and is not for use in filtering hazardous materials.

When cleaning the filter, remove dust by using pressure air 482 kPa (70 psi), with an 3.18 mm (.125 in) OSHA approved nozzle at least 50.8 mm (2 in) away from the filter element. Do not clean the filter element with water.
