Fundamental Difference: Completely Different Working Principles Although both are called “automatic filters,” their cleaning mechanisms are essentially different. 1. Working Principle of a Self-Cleaning Filter Cleaning Mechanism: Mechanical brushing + discharge. A motor drives a brush or scraper to physically remove impurities attached to the…

An automatic backwash filter is a self-cleaning filtration system designed to ensure continuous operation. When impurities accumulate and the inlet–outlet pressure differential reaches the preset value, or after the set time interval, the control system automatically initiates the cleaning process. Main Features Zero downtime maintenance…

The selection of an automatic backwash filter should be based on the medium type, flow rate, pressure, and other parameters. Details are as follows: Medium Type Examples: fresh water, seawater, lubricating oil, etc. For seawater or corrosive media, stainless steel or copper-nickel alloy materials are…

Brief Description of Operation Steps of Automatic Backwash Filter: Filtration Stage: The medium flows in from the inlet, passes through the filter element, and impurities are retained while the clarified liquid flows out. Differential Pressure Monitoring: When the pressure difference between the inlet and outlet…

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…

The brush-type self-cleaning filter is a precision device that uses a filter screen to directly intercept impurities in the water, remove suspended solids and particles, reduce turbidity, purify water quality, and minimize the formation of fouling, microorganisms, algae, and corrosion. Its purpose is to purify…

A self-cleaning filter is a separation and filtration device that automatically removes particles from liquids under certain conditions. Different mesh specifications can be selected according to the required filtration particle size. At present, as a new type of water treatment equipment, self-cleaning filters are increasingly…

An automatic backwash filter is a device capable of automatically cleaning the filter element and achieving continuous filtration. When impurities accumulate and cause the pressure differential between the inlet and outlet to reach or exceed the preset value, or when a preset time is reached,…

The key feature of a backwash filter is its ability to perform self-cleaning based on specific conditions, primarily referring to the differential pressure between the inside and outside of the filter elements (which reflects the cleanliness of the elements). The internal structure of the backwash…

Disconnect the motor wiring as needed. Note: When reconnecting the wiring, please ensure the motor rotates in the correct direction. For brush-type self-cleaning filters, rotation direction has no effect. However, incorrect rotation may damage the scraper inside scraper-type filters. Disconnect the valve wiring as needed.
