The SUREFLOW™ Static Pressure Controller Model 8635-ST is designed to maintain a constant duct static pressure. The 8635-ST controller measures the actual static pressure using a pressure transducer. The 8635-ST controller is easily configured to accept different pressure transducer ranges, allowing it to be used for almost any duct.

The 8635-ST controller will modulate a damper or variable frequency drive to maintain the proper duct static pressure.

The 8635-ST easily integrates to the building management system using alarm relays, an analog output of the measured static pressure, or digital communications. The 8635-ST supports the open MODBUS protocol.
