ARA - Model PM 2.5 VIS-A Cyclone -Vortex Inversion Separator -

The ARA VIS-A (Vortex Inversion Separator) is a precision engineered and compact sharp-cut cyclone fitted to the N-FRM inlet that physically selects particles 2.5 microns and below. This ensures precise measurement of only the PM2.5 size fraction.  The PM2.5 separator is designed to operate at 1 cubic meter per hour (16.67 liters per minute) and requires the ARA PM10 omnidirectional inlet to collect accurate PM2.5 samples. PN 520-000.
