    Valve Adjustable Technology

    Controllable nebulization rate at consistent particle size
    vat detail picture botteleThe proprietary adjustable valve is able to deliver medications of different viscosity level according to every user’s conditions without exchanging parts. The Valve Adjustable Technology (VAT) bottle allows users to adjust different levels of Nebulization rate 0.15 (closed) / 0.5 (fully opened) ml/min at consistent particle size. Higher nebulization rate (fully opened) is for higher viscosity medications and higher breathing capacity user while lower nebulization rate with closed valve will be more appropriate for kids/infants with lower breathing capacity. VAT is recommended for respiratory disorders such as Chronic Obstructive Pulmonary Disease (COPD) and asthma as well as intensive use in general.
