Piston Nebulizer Rossmax NA100 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. MMAD ≤2.2 μm; Fine Particle Dose (FPD): 80-85% Consistent fine particle size for efficient respiratory treatment Patented Valve Adjustable nebulizer bottle (VAT) Powerful Piston compressor Mouthpiece and masks for adult and child included Built-in Compartment for Accessories Valve Adjustable Technology Controllable nebulization rate at consistent particle size The proprietary adjustable valve is able to deliver medications of different viscosity level according to every user’s conditions and needs at ease. Our VAT technology allows users to adjust different levels of nebulization rate ranging from 0.15 – 0.40 ml/min at consistent particle size. The nebulization rates can be adjusted by the user in a very easy way without exchanging parts. High nebulization rate/full open is for high viscosity medications and high breathing capacity user while low flow rate with close valve will be more appropriate for kids / infants with lower breathing capacity. Thanks to the reduction of wasted medication, VAT is also recommended for respiratory disorders such as COPD and Asthma as well as intensive use in general. The following Nebulizers are equipped with our VA Technology. Efficent Respiratory Utilizing the new technologies to improve the management and treatment of asthma, COPD and other respiratory conditions. With nebulizer systems, patients have the ability to effectively manage and treat their respiratory condition anywhere, anytime.
