Marine Mist Eliminators: Tough Protection for Tough Conditions

Air Defence’s marine mist eliminators help keep air systems on ships clean and dry. In Australia’s tough marine environments—full of salt, moisture, and sea spray—these units stop water and mist from getting into engines, electronics, and air systems.

What Is a Mist Eliminator?

A mist eliminator is a filter that catches tiny drops of water or oil floating in the air. It’s used in ventilation and engine systems to stop moisture from causing damage inside ships and offshore platforms.

Why It’s Important on Ships

Salt and moisture in the air can hurt engines, electronics, and other equipment. Mist eliminators:

Stop rust and corrosion on important parts
Clean the air going into HVAC and engine systems
Keep water out of pipes and filters
Make systems work better and last longer

These are key for defence teams, shipbuilders, and marine engineers working in harsh sea conditions.
