A respirable cyclone sampler for a flow rate of 20 l/min

• A high-flow respirable sampler GK6.27 has been developed and investigated. • The aspiration efficiency and internal penetration of the sampler have been studied. • The sampler performance has been assessed according to EN 13205-2. • Particle travelling time and distance in the sampler have been estimated. • Particle distribution on the filter has been simulated.
