Technical Data Sheet
Eastman™ Turbo Oil 2330
Key Attributes
Improves odors
Less unplanned maintenance
Runs cleaner
Product Description
Airlines have used turbo oils originally designed for turbine engine applications within their planes’ APUs since modern aircraft were developed. The APU powers electrical components while the plane is on the ground and helps start the main engines before takeoff. It also helps with engine restarts when the plane is airborne.
Turbo oil can leak from equipment and may enter the cabin air system, reacting with heat and water to generate a foul odor in the cabin. Such events can lead to aircraft groundings, costing airlines time and money while they investigate the cause. These events can also leave passengers stranded and dissatisfied.
ETO 2330 helps mitigate this issue by reducing unscheduled maintenance related to odors. With an inoffensive odor profile, ETO 2330 keeps more planes airborne, bolsters airline operational efficiency and improves the passenger experience.
