Review the AFT11 Series Coupler Guide for port connection options:
SS11LB AIRFLOW CONNECTIONS
The SS11LB transducer uses flow head RX117A, which has multiple outer diameters to directly connect to the AFT36 mouthpiece/filter, AFT7L tubing, and other pulmonary products. The tiered airflow head has a different design than the SS11LA so different couplers are required for other BIOPAC airflow parts.
| AFT Series Part # | RX117A Flow Head Coupler/Combination/Notes |
| AFT1 | Direct connection to SS11LB, but not recommended due to airflow restriction;Â use AFT36 in place of AFT1 + AFT2. |
| AFT6A | Not recommended for SS11LB. Use FLOWCAL calibration kit. May still be connected to the SS11LB using the AFT11A coupler included with the AFT6A. |
| AFT7L | Direct connection to SS11LB. |
| AFT8 Autoclavable Mouthpiece | Either connect directly if sterilizing airflow head. If not sterilizing head can use AFT4 disposable filter (connect AFT8 to smaller diameter of filter, larger diameter to SS11LB). |
| AFT9 35mm Reusable Mouthpiece | Replaced by AFT8 Autoclavable Mouthpiece. The AFT8 has a better fit with the SS11LB. |
| AFT10 Disposable Facemask | AFT11H 35 mm OD/28.6 mm ID. |
| AFT12 | Direct connection to SS11LB. Snug, but fits in the inner diameter of airflow head. |
| AFT13 (OBSOLETE) | AFT13 has been discontinued. Replaced by the AFT36 mouthpiece/filter. |
| AFT23 Low-cost T-Valve | Reusable mouthpiece: AFT4 + AFT8 + AFT11D 35 mm OD/35 mm ODDisposable mouthpiece:Â AFT36 + AFT11D 35 mm OD/35 mm OD |
| AFT26 2 L syringe | AFT11D 35 mm OD/35 mm OD. This coupler is included in the FLOWCAL calibration kit. |
| AFT36 Disposable Filter with Integrated Mouthpiece | Direct connection to SS11LB. |
