A dehumidifier is specifically designed to remove moisture and water vapor from the air, making it an effective choice for controlling humidity levels within the interior of machinery such as the MRG (Main Reduction Gear). By reducing humidity, the dehumidifier helps prevent potential issues associated with excess moisture, such as corrosion, reduced lubrication efficiency, and other moisture-related damage that could affect the operation and reliability of the gear system.

While a vacuum pump can help in creating a vacuum environment, it primarily removes air rather than focusing on moisture specifically. A condensate trap is intended to collect and remove condensate (liquid water) that forms due to temperature changes, but it does not actively dehumidify the air. An air filter serves to clean the air by trapping particles and contaminants but does not address moisture levels.
