Details

Retrofitting a PM10 high volume air sampler allows for characterization of PM2.5 with existing methodologies.
 

Ambient air enters the PM2.5 Inlet at a flow rate of 40 cfm (1.13 m3/min) through an opening under the weather-proof hood. The air then flows into a stilling chamber and through a screen that is designed to prevent the entry of insects and large-sized airborne debris into the fractionating system. From the stilling chamber the air flows through a set of 40 impactor jets that direct air towards a wetted collection surface. Particles with sizes larger than 2.5 microns aerodynamic diameter impact upon a porous disc wetted with oil. Particles smaller than 2.5 microns are vented from the impaction zone and flow downward to the standard 8 x 10-inch (20.3 x 25.4cm) hi-vol sampling filter.

Features

Retrofit an existing high volume air sampler at only a fraction of the cost of a new PM2.5 system
