The ASC-Filter range from Shalin, works based on Bernoullis principle. ASC filters are equipped with a timer circuit and a differential pressure switch. The filter continues its operation until preset timer value is reached or a differential pressure value is reached.
The filter enters into cleaning mode on trigger by any of these two inputs. On receiving signal the control panel opens the auto drain valve and after short interval, a piston fitted with a sweeping disk in a closed filter chamber is moved up and down. This action creates low pressure and high pressure zones inside the same vessel due to varied velocities between moving disk and filter screens.
As a result of this flow reversal takes place dislodging the clogged impurities from the filter screens. Once the piston completes cleaning cycle the drain valve is automatically closed and filter resumes next cycle.
The USP of Shalin's ASC filter is it continues to filter inlet stream while the cleaning is in progress.
