Automatic Strainer Self Cleaning

The self-cleaning filter system integrates the filter unit, automatic control system, cleaning mechanism and other components. It intercepts impurities in the fluid through the filter. When the preset pressure difference, time or turbidity conditions are reached, it automatically starts the brushing, backwashing and other cleaning procedures to remove the dirt on the filter to maintain high-efficiency filtering performance. It is an intelligent filtering equipment combination that does not require frequent manual disassembly and cleaning.

Product advantages

Automatic Operation

Fully automatic self-cleaning system eliminates manual maintenance and reduces labor costs while ensuring continuous filtration.

Continuous Filtration Without Downtime

Cleaning is performed during operation, allowing uninterrupted production and stable system performance.

Lower Operating & Maintenance Costs

Reusable filter screen and automatic sludge discharge significantly reduce replacement frequency and maintenance expenses.

Reliable Equipment Protection

Effectively removes solid particles to protect pumps, valves, heat exchangers, and downstream equipment, extending overall system service life.

FAQ

What types of liquids can an automatic self-cleaning strainer handle?
Automatic self-cleaning strainers are suitable for water, cooling water, process water, seawater, wastewater, oils, and various low-viscosity industrial liquids containing suspended solids or particles.

Does the system need to stop during the cleaning process?
No. The self-cleaning process is performed automatically while filtration continues, ensuring uninterrupted system operation and continuous production flow.

How is the cleaning cycle triggered?
The cleaning cycle can be activated by differential pressure, preset time intervals, or PLC control depending on operating requirements and system configuration.
