PM 10 Inlet


The ARA omnidirectional PM10 Inlet is a compact version of the EPA prescribed Reference Method Inlet. It features a screened inlet, wind deflector, and precision PM10 inertial separator (impactor) with moisture trap.  The PM10 Inlet is designed to operate at 1 cubic meter per hour (16.67 liters per minute).  The inlet can be used alone for PM10 sampling or in combination with the ARA VIS-A sharp cut vortex inversion separator for PM2.5.
