Automatic Water Filters Self Cleaning Rotary Filter

Product Details

Scraper filter introduction 

Inoco scraper filter is automatically controlled, which is the auto self cleaning filter, with feature of automatically operation, high filtration precision, stable and reliable performance, is an effective choice of replacing manual filter or use dumping type material filter, bag filter, basket filter, vibrating screen filter.XF-S1 series cylinder scraper automatic self-cleaning filter is ideal choice of high viscosity filtration, high corrosion resistance, and high pressure liquid, which is self-developed by inoco company, this new generation of mechanical of auto self cleaning filter has reached the world advanced technology level.

Operation principle 

 Inoco mechanical cleaning filter’s operation principle is very simple: install the filter screen (2) in a stainless steel cylindrical shell(1). When unfiltered liquid flows into the shell from the inlet (3), solid impurities were leached and deposited on the inner surface of the screen. Filtered liquid flows out from the outlet (4). When filter screen need cleaning (depending on the time, pressure differential, or manually choose), a clean dish tightened with spring scrapes the mesh inside surface back and forth constantly and removes the deposition of solid material. When the debris is separated from gap of the filter screen, wash dish will send the dirt into the bottom of the shell (6) and discharged through the flow channel(7).
 Pneumatic cleaning plate drives through air pressure (60-80 psi @ 5 CFM). S-01 and S-02 filter’s main characteristic is that they can be driven by single cylinder or double cylinder. The smaller S- 01 model is only equipped with a cylinder.

 i. Scraper filter is not only used for auto water filter, but also widely used in self cleaning filtering of solvents, acid alkali, polymer, coating adhesive materials.
 ii. High efficiency and precision range of 30-1500 microns, liquid viscosity up to 800,000 CP.


 The inoco scraper filter is widely used in water treatment, petrochemical, metallurgy, electric power, chemical, paint, printing ink, paper, food and beverage, pharmaceutical, metal processing industries and etc.
