Ships operate in harsh environments with high temperatures, high humidity, and high salt spray, making filtration systems crucial.
Main Engine Intake Purification: Marine diesel or gas turbine engines handle large air volumes. Filtration systems must efficiently intercept sea salt particles to prevent thermal corrosion while keeping pressure drop extremely low for engine fuel economy.
Ballast Water Treatment Auxiliary: In ship ballast water management systems, physical centrifugal or mesh filtration is the first step. It removes large - diameter aquatic organisms and sediment, protecting subsequent ultraviolet or electrolytic disinfection units.
Hydraulic and Steering Systems: Ship steering and heavy - duty machinery rely on hydraulic power. High - pressure physical filters maintain absolute cleanliness of hydraulic fluids, preventing deep - sea navigation and maneuvering failures due to metal particle wear.
Crew Living Environment: For long - term enclosed cabins, air conditioning and filtration systems (HVAC) must be mold - proof, dehumidify, and filter fine particulate matter to ensure crew health on long voyages.
