TSI RPC30 PresSura Hospital Room Pressure Controller


The PresSura™ Room Pressure Controller Model RPC30 is designed to maintain a constant pressure differential in hospital rooms. Backed by TSI’s unique thermal-based pressure sensor, the PresSura products offer the most accurate, precise, and stable measurement available. The RPC30 continuously measures room pressure, verifying proper airflow and pressure direction in Airborne Infection Isolation (AII) Rooms, Protective Environment (PE) Rooms, and Operating Rooms (ORs). The Model RPC30 then controls a damper or valve to maintain a safe pressure differential as the specialized room conditions might change. The Model RPC30 can also accept temperature and relative humidity inputs, for complete room environmental monitoring. PresSura Products help hospitals ensure safety for patients and staff.


A large, local monitor provides easy visual indication of room status. If pressure is lost, the RPC30 activates audible and visual alarms, alerting staff to the alarm condition. The RPC30 even accepts supply and exhaust volumetric flow measurements, alarming if the ventilation rate is too low. The RPC30 features adjustable alarm delays to avoid nuisance alarms. When the room is unoccupied, it can be changed to no isolation mode, deactivating all alarms.
