Sterilizable 22 mm ID/30 mm OD air flow head for older pneumotach transducers TSD117, SS11L, and SS11LA. The material used in the flow head is polycarbonate and the screen is Stainless Steel. This detachable flow head is dishwasher safe.
Newer pneumotach transducers TSD117A and SS11LB use RX117A-MRI Tiered ID/OD. The Tiered airflow head design allows for direct connection to multiple standard pulmonary ID/OD hoses and components without the need for couplers. Works with standard and -MRI transducers.
