What Is Marine Automatic Self Cleaning Filter

JX Filtration August 22, 2025 Self Cleaning Filter

Marine Automatic Self-Cleaning Filter is widely used in marine cooling water systems (especially when seawater is used as the cooling source), ballast water systems, and lubrication oil systems. Its purpose is to filter out particulate impurities from the medium, while performing automatic online backwashing to maintain filtration performance and extend operating time.

Detailed Description of the Equipment

Internal Structure and Components

The internal structure of an Automatic Self-Cleaning Filter may vary slightly depending on the brand and model, but the core components are generally the same:

Component	Function Description
Filter Housing	A pressure vessel containing the filter element assembly; commonly made of carbon steel, stainless steel, or seawater copper alloy.
Filter Element	The key component for filtration, typically made of wedge wire mesh, stainless steel mesh, or sintered mesh; pore sizes generally range from 50 to 500 μm.
Backwash Mechanism	Includes rotating cleaning brushes/nozzles, driven by an electric motor or hydraulic system.
Differential Pressure Sensor	Detects pressure difference between inlet and outlet to determine when cleaning is required.
Electric/Hydraulic Control System	An automated control unit for managing cleaning operations, compatible with PLC integration.
Flush Valve	Opens to discharge impurities from the filter element surface, completing the backwash cycle.
