• Valve Adjustable Technology 

    Controllable nebulisation rate & consistent particle size


    The proprietary adjustable valve is able to deliver medications of different viscosity levels according to every user's conditions without exchanging parts.


    The Valve Adjustable Technology (VAT) bottle allows users to adjust different levels of nebulisation rate 0.15 (closed) / 0.4 (fully open) ml/min at consistent particle size less than 2.2 μm. Higher nebulisation rate (fully opened) is for higher viscosity medications and higher breathing capacity users. Lower nebulisation rate with closed valve is 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.


    Particle size created by our VAT bottle is around 2.19 μm (MMAD) tested by Cascade Impactor and 3.221 μm tested at Dv(50) by Malvern Spraytec. Compared to most bottles in the market, our proprietary bottle ensures more efficient and effective performance.
