Sand Sediment Removal 304 316 Stainless Steel Brush/Scraper Automatic Self-cleaning Water Filter
Working Principle:
The fully automatic self-cleaning filter works by passing water or other fluids through a filter screen to remove impurities. As the fluid flows through the screen, particles are trapped, and over time, the screen accumulates debris. When the pressure difference across the screen reaches a set level, the system triggers a cleaning cycle. This is done using a rotating or backwashing mechanism that removes the trapped particles and flushes them out, ensuring continuous filtration without manual intervention.
Advantages:
1.Efficiency: Provides uninterrupted filtration with minimal downtime.
2.Low Maintenance: Automatically cleans itself, reducing the need for manual cleaning or maintenance.
3.Cost-Effective: Saves on labor and operational costs over time.
4.Environmentally Friendly: Reduces water waste compared to traditional filters.
5.Versatility: Suitable for a wide range of applications, including water treatment, industrial processes, and irrigation.

The self-cleaning cycle begins in any of the following situations:
1. Receive signals from differential pressure switches
2. Set the time interval parameter on the control board
3. Manually start
