occurs first. It cannot be interchanged with air
filter elements used on previous Thermo King
truck units.
Oil Bath Type
A heavy duty, oil bath air cleaner filters all of the
air entering the engine. Excessive restriction of
the air intake system reduces the flow of air to the
engine affecting horsepower output, fuel
consumption and engine life.
The air cleaner removes abrasive material from
the air entering the engine. The air cleaner must
be kept clean and open so that the air can pass
freely. If the oil has absorbed the maximum
amount of dirt, it allows the dirt to enter the
engine. Remove the oil cup, wash thoroughly and
dry every 1000 operating hours (500 hours under
dusty conditions). Refill using the same weight oil
used in the engine crankcase. Inspect the cleaner
body and wash in solvent when it becomes dirty.
Dry Type (Optional)
A dry element air cleaner filters all of the air
entering the engine. Excessive restriction of the
air intake system affects horsepower, fuel
consumption and engine life. Inspect the element
at regular unit service intervals.
