PresSura Hospital Room Pressure Controllers 8630-PC
Request A Quote
The PresSura™ Room Pressure Controller Model 8630-PC is designed to maintain a constant pressure differential in hospital rooms.
The 8630-PC measures the actual room pressure differential using TSI’s unique bi-directional pressure sensor. It modulates a damper or 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-PC will activate audible and visual alarms. The 8630-PC even accepts supply and exhaust volumetric flow measurements, alarming if the ventilation rate is too low.
The 8630-PC 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-PC 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.
