The PresSura™ Room Pressure Controller Model 8631-HC is designed to maintain a constant pressure differential in hospitals. It measures the actual room pressure differential using TSI's unique, bidirectional pressure sensor, and modulates a damper or variable frequency drive to maintain set point. If the pressure differential is too great, too small, or the wrong direction, the 8631-HC will activate audible and visual alarms.
The 8631-HC also helps avoid nuisance alarms. Adjustable alarm delays allow traffic to enter the room without triggering alarms. Should a non-infectious patient be housed in the room, the nursing staff can set the monitor to no isolation mode, deactivating the alarms.
The 8631-HC easily integrates to the building management system, using LonWorks®, an analog output and alarm relays.
