PM-2.5 Sampling Inlet

PM-2.5 Size Selective Sampling Inlet with filter holder.

HI-Q Environmental Products Company's, EPA Designed, PM-2.5 Sample inlet operates on the same principles of particulate impaction as the PM10-INLET described above. Air is drawn into the omnidirectional inlet head at a flow rate of 16.67 LPM. The air is then accelerated toward the first impaction stage where particulate with aerodynamic diameters greater than 10mm are collected (filtered out). The air stream, carrying particulate 10 microns and smaller, continues down the inlet toward the second impaction stage where particles larger than 2.5 microns are collected. Finally, particulate 2.5mm and smaller continue down the inlet where they are collected on a 46.2 mm diameter, ring supported filter media disc.
