PM10 Size Selective Inlet

Model G1200 (RFPS-1287-063)

The model G1200 High Volume PM10 Size Selective Inlet (SSI) samples suspended particles in the air at 40 ACFM (1.13 ACMM) through the circumferential inlet. The symmetrical design insures wind direction insensitivity. The inlet design and internal configuration makes the collection efficiency independent of wind speed from 0 to 36 kilometers per hour.

The particles are then accelerated through none circular acceleration nozzles. B virtue of their larger momentum, particles greater than 10 microns, aerodynamic diameter, impact onto a greased impaction shim plate. The particles smaller than 10 microns are carried vertically upward by the air flow and down sixteen vent tubes to the 8" x 10" quartz fiber filter (PIN-GQMA) where they are collected. The large particles settle out in the impaction chamber on the collection shim plate and are removed by cleaning during prescribed maintenance periods This inlet is adaptable to all Andersen Instruments High Volume Systems.
