50.28 SSF.DP Bag Housing - Product Specification

Overview

The 50.28 SSF.DP Bag Housing is a skid-mounted sidestream filtration system designed to process a portion of water from the main circuit through a polypropylene bag filter. It features a differential pressure switch to monitor the pressure drop across the filter, ensuring reliable performance and timely maintenance. The system is equipped with simple and intuitive controls, including a rotor power isolator and start/stop push buttons, while offering essential status outputs for integration with Building Management Systems (BMS).
