Product Details

This unit has been discontinued as of December 15, 2016.

The PresSura™ Room Pressure Controller Model 8630-SC is designed to maintain a constant room pressure differential in hospital rooms.

The 8630-SC measures the actual room pressure differential using TSI's unique, bi-directional pressure sensor. It modulates a damper or the variable frequency drive to maintain a safe pressure differential. If the pressure differential should rise too high, fall too low, or go to the wrong direction, the Model 8630-SC will activate audible and visual alarms. The Model 8630-SC even accepts a volumetric flow measurement, alarming if the ventilation rate is too low.

The 8630-SC features adjustable alarm delays to avoid nuisance alarms. When the room is unoccupied, it can be changed to no isolation mode, de-activating all alarms.

The 8630-SC easily integrates to the building management system using a low alarm relay and an analog output of the measured pressure differential, or digital communications over an RS-485 network using the open MODBUS protocol.
