Airflow Face Mask (with T-Valve)

This Airflow Face Mask (AFT25) is a high-performance, low dead space, low airflow resistance face mask. It is suitable for a variety of different high pulmonary function measurement applications including exercise physiology and sleep studies (PSG).

The Airflow Face Mask consists of a plastic mouth-breathing face piece, an integral T-valve, and a head strap (cap).  The T-valve is an integral part of the face mask and is non-rebreathing. The connection ports of the T-valve have an outer diameter of 35 mm and an inner diameter of 28 mm. The face mask incorporates two gas sampling ports (female Luer) for interfacing with a gas sampling kit (e.g., AFT20).
