Self Cleaning Filter

Self-cleaning filters are designed to separate oversized contaminated particles from liquids. The role of an automatic self-cleaning filter allows liquid to be continuously filtered through the machine while keeping the insides of the machine clean simultaneously. The mechanical scrapers inside the filter remove oversized materials stuck on the machine surface. This process is automated to avoid manual intervention. The device can filter particle sizes between 100 to 10 microns, depending on the filter type and the liquid being filtered.

The contaminated coolant/oil is pumped from the application into the self-cleaning filter from the top and flows into the inner diameter of the drum. The contaminants are retained on the inner diameter while the clean coolant flows past the outer diameter and out the filter drum. The clean coolant is drawn out by pressure into the exit or outlet port. As the contaminant layer or cake builds up, the differential pressure increases. At a pre-set pressure, the drain port opens up and the sludge is pushed out of the machine by a geared brush/scraper. Once the flushing cycle is completed, the brush/scraper is stopped and the drain valve shuts. The drain valve can be connected to oil recovery systems for further oil recovery from the sludge. These filters operate from inside to outside where the brushing/scrapping occurs inside the filter.

  • Free from manually cleaning clogged filtration systems

  • Vertical Type Self-Cleaning Filter
    In the vertical type, the contaminated coolant is passed into a filter through an inlet pipe placed on top and the vertical drum filter will collect the dirt. The clean filtered coolant will be discharged through an outlet pipe at the bottom.

 

  • High-Temperature Self-Cleaning Filter
    High-temperature self-cleaning filter types are mainly used in food and beverage, chemical and coating industries. These filters are essential for handling operations that deal with high temperatures. These filters can withstand temperatures up to 70 °C (160 °F) and can be customized to handle higher temperatures as well.
