Heavy Duty Piston NebulizerParticle size created by our VAT bottle is around 2.07 μm (MMAD) tested by Cascade Impactor. 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 treatmentPatented Valve Adjustable nebulizer bottle (VAT)Low noise with silencer and vibration-absorber designFine ventilation design to ensure heavy duty usePowerful Piston compressorMouthpiece and masks for adult and child includedBuilt-in nebulizer kit holderValve Adjustable TechnologyCONTROLLABLE NEBULIZATION RATE AT CONSISTENT PARTICLE SIZEThe 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 – 0.50 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.
