Valve Adjustable Technology<br />

Controllable nebulization rate at consistent particle size<br />

The proprietary adjustable valve is able to deliver medications<br />

of different viscosity level according to every user’s<br />

conditions without exchanging parts.<br />

The Valve Adjustable Technology (VAT) bottle allows<br />

users to adjust different levels of Nebulization rate<br />

0.08 (closed) / 0.4 (fully opened) ml/min at consistent<br />

particle size. Higher nebulization rate (fully opened)<br />

is for higher viscosity medications and higher breathing<br />

capacity user while lower nebulization rate with closed<br />

valve will be more appropriate for kids/infants with lower<br />

breathing capacity. VAT is recommended for respiratory<br />

disorders such as Chronic Obstructive Pulmonary Disease<br />

(COPD) and asthma as well as intensive use in general.<br />

Aerosol Performance Tested with 0.9% saline<br />

The average particle size of our nebulizer with VA Technology<br />

is around 2.1μm (MMAD), and FPD (Fine Particle<br />

Cascade Impactor Malvern Spraytec<br />

Dose) MMAD is above 81% FPD tested by Dv(50) Cascade Impactor FPD which<br />

ensures 2.26μm more efficient 86.74% and effective 4.77μm treatment. 60.19% Please review<br />
