Exit Valve

The Exit Valve fits on the bottom of the Flexineb® Mask and allows exhaled air escape when the horse exhales. The Exit Valve can be rotated to open vents in the bottom of the Mask if the horse needs extra air or when introducing the Flexineb® for the first few times. It should be closed when nebulising drugs and natural therapies so the horse is forced to inhale through the Aerosol Chamber and inhale the nebulised drug.
