The ResMed HumidAire 2i Tub Assembly PC (REF-30951) is a specific component—the standard water chamber—for the older, discontinued ResMed HumidAire 2i Heated Humidifier system.
It is designed for use with the ResMed S7 series CPAP machines and the VPAP III series BiLevel machines. The “PC” in the name indicates it is the clear polycarbonate version, which is intended for manual cleaning and high-level thermal or chemical disinfection, but not steam sterilization.
