HV-RW (for Andersen) is a particle separating air sampler, with an impactor equipped with a multi-stage porous jet nozzle. It is designed to collect particles suspended in the air that penetrate the respiratory system. The particle size separator main unit consists of 4 overlapping particle separating stages. It separates out aerosols between 1.1 and 7.0 μm in size. Aerosols smaller than 1.1 μm are filtered out by a backup filter.The sampling flowrate is stabilized by combining a constant flowrate unit and a suction blower.
