The threshold controlled, breath-synchronous application of the preset aerosol dose during the inspiration phase guarantees outstanding reproducible results. FEATURES Perfect user guidance, simple handling and well-structured display Creation of own multiple stage tests with easy-to-use software Storage of unlimited protocol amount with up to 14 stages – the most commonly used ones already installed (e.g. ATS, DGP) Due to optimal droplet size, constant over entire bolus time, aerosol reaches respiratory tracts particularly deeply Dose-changing by increasing fluid concentration and/or changing atomizing time Highly effective filter for exhaled air prevents contamination of room air Three-liter compressed air tank for stable atomizing pressure, refilling in less than 2 minutes at a low noise level Components for single-patient use ensure perfect hygiene and safety
