What is a Self-Cleaning Filter?
A self-cleaning filter is an automated filtration system that removes contaminants from liquids (water, oil, chemicals, etc.) without requiring manual cleaning. It uses an integrated cleaning mechanism (backwashing, scraping, or suction scanning) to maintain optimal performance with minimal human intervention.
Key Advantages of Our Self-Cleaning Filters:
✔ Fully automatic operation – No need for manual cleaning or frequent maintenance.
✔ Continuous filtration – No downtime for cleaning, ensuring uninterrupted production.
✔ Cost-effective – Reduces labor and maintenance expenses.
✔ High filtration efficiency – Removes particles as small as 10 microns (customizable).
✔ Durable construction – Made from stainless steel, carbon steel, or special alloys for corrosion resistance.
✔ Energy-saving – Low-pressure drop design minimizes energy consumption.
How Does a Self-Cleaning Filter Work?
Our self-cleaning filters operate based on a smart filtration and cleaning cycle:
1. Filtration Phase
The liquid enters the filter and passes through a stainless steel mesh or wedge wire screen.
Contaminants are trapped on the filter surface while clean fluid exits the system.
2. Cleaning Phase (Automatic)
When the pressure drop across the filter reaches a set limit (due to accumulated debris), the cleaning cycle activates.
Depending on the model, cleaning is performed via:
Backwashing (reversing flow to flush out debris)
Mechanical scraping (a brush or scraper removes particles)
Suction scanning (a suction scanner cleans the filter element)
The waste is discharged through a drain valve, keeping the filter clean without stopping production.
3. Resumption of Filtration
Once cleaning is complete, the system returns to normal filtration mode.
