Scraper type self-cleaning filter

Product Introduction

Scraper type self-cleaning filter's liquid from the filter inlet into, flow from top to bottom, through the filter surface flow to the outlet; When a certain amount of impurities are collected on the surface of the filter element, the motor drives the scraper equipped with the calibrator to rotate close to the surface of the filter element and scrape off the impurities. The impurities gather in the collection chamber along with the downward liquid. When a certain amount of impurities are accumulated, the automatic blowdown valve opens the collection chamber to discharge the liquid containing high concentration of impurities and discharge the residual liquid for recovery or discharge.

Note: Internal scraper means the scraper is inside the filter, and external scraper means the scraper is outside the filter.
