Anti Asphyxiation Valve (AAV) Port Assembly (HRRP201521)
This product is for use with the Hans Rudolph V2™ range of face masks.
The AAV allows you to breathe room air when your ventilator is not switched on. The AAV diaphragm closes the room air port during CPAP ventilation. It opens to allow you to breathe room air when your ventilator is off.
Your mask shouldn't be used if the AAV is missing, damaged or not functioning properly.
The AAV Port Assembly snaps into the swivel port assembly elbow using locking tabs for engagement.
