Respirable Dust Sampler



Particulate air pollution is separated into three classifications; coarse, fine and ultrafine particles. Coarse particles have a diameter of between 10µm and 2.5µm and settle relatively quickly whereas fine (0.1 to 2.5µm in diameter) and ultrafine (<0.1µm in diameter) particles remain in suspension for longer.

Our Respirable Dust Sampler AI-101 for PM10 sampling in ambient air uses the NEERI designed cyclone with sharper cut-off at 10 microns to separate the bigger particulates from the air stream before filtering it on the glass micro fibre filter. By using the AI-101, measurement of Respirable Particulate Matter can be done accurately and TSPM can also be measured by collection of dust collected in the dust cup at the bottom of cyclone. The Cabinet design is upgraded for easy lesser height of machines thus contributing lesser total weight of machine and helps in easy transportation of it from site to site. The AI-101 can be easily paired with a gaseous sampling attachment for sampling of gases like SO2, NO2, NH3, O3 etc.
