DF flow selector for aerosol therapy

The DF flow selector, used in conjunction with Rs and Qmed® flowmeters, allows to divert the supplied gas through an humidifier or through a hose connector to connect devices used for aerosol therapy.

The DF flow selector can be connected through its threaded ring to the flowmeter or supplied directly integrated in the Rs body. The flow can be easily directed to the humidifier for oxygen therapy, through the axial outlet, otherwise it can be diverted through a side hose connector for aerosol therapies.
