Product Features
1.Continuous Filtration Without Shutdown
The filter automatically initiates the cleaning cycle according to differential pressure or a preset time, eliminating the need for routine manual filter-screen removal.
During cleaning, a negative-pressure suction nozzle moves along the filter screen to remove accumulated sediment and suspended contaminants, while the electrically operated discharge valve opens to release the collected wastewater.
Once cleaning is completed, the discharge valve closes and the system returns to normal filtration. The main filtration flow remains uninterrupted throughout the cleaning process, allowing continuous operation without routine shutdown.
2.Negative-Pressure Suction Cleaning
A negative-pressure suction nozzle moves axially along the filter screen and directly removes accumulated contaminants from its surface, making the suction-based cleaning method suitable for fine filtration.
3.PLC-Based Automatic Control
The PLC works with a differential-pressure sensor to monitor filter loading and control the cleaning sequence, while the control panel provides an operating interface for monitoring and managing the automatic filtration process.
4.Compact Pipeline Integration
The filter can be installed directly into the process pipeline, with vertical or horizontal configurations available according to the equipment and installation requirements.
5.Reusable Stainless Steel Filter Screen
The stainless steel filter screen is designed for repeated automatic cleaning, reducing the need for frequent replacement of disposable filter bags or cartridges.

- Flow rate, working pressure, and operating temperature
- Cleaning and discharge configuration
- PLC control and control-panel configuration
- Installation orientation and connection requirements
- Equipment configuration for specific process applications
From equipment configuration to final production, the customization approach allows the filtration system to be matched to the customer's process requirements rather than relying on a fixed standard configuration.
FAQ
Q1: What makes a Continuous Self Cleaning Filter different from a conventional filter?
A:The main difference is the cleaning process. A conventional bag or basket filter generally requires manual intervention to clean or replace the filtration element. It automatically removes accumulated contaminants from the filter screen while maintaining the main filtration flow.
Q2:Does the filter need to stop during cleaning?
A:The main filtration flow does not need to stop during the automatic cleaning cycle. In multi-element configurations, different filtration zones can be cleaned sequentially while other elements continue filtering.
Q3:Does the filter screen need to be replaced frequently?
A:The stainless steel filter screen is designed for repeated cleaning and reuse. Its service life depends on the process fluid, contaminant characteristics, operating conditions, and maintenance requirements.
Q4:Is a Continuous Self Cleaning Filter suitable for RO pretreatment?
A:It can be used for suspended-solid removal upstream of RO systems as part of a pretreatment arrangement. The required filtration accuracy and configuration should be selected according to the specific RO process and upstream water quality.
Q5:What information is needed to select a filter?
A:The key information includes fluid type, contaminant characteristics, flow rate, required filtration accuracy, working pressure, operating temperature, pipeline diameter, and whether continuous filtration is required.
