Particle Size Separating Cyclones

Tisch Environmental PM cyclones are precision particle fractionators used to separate ambient aerosols by aerodynamic diameter. Larger particles above the target cut point collect in a removable cup, while smaller particles continue through the downtube to the sampling filter.

Designed for use downstream of a standard US EPA PM10 inlet, these cyclones deliver accurate size-selective sampling for PM2.5, PM4, and PM1 at a flow rate of 16.67 L/min.
