The Model 400 consists of a single-stage impactor followed by a filter to collect particles for mass or chemical analysis. Aerosols are sampled through the impactor to remove coarse particles above the impactor cut-point. Impactor cut-points of 2.5 and 10 µm are available for PM2.5 or PM10 sampling. The sampling flow rate is 10 liters per minute.

The system includes a small, quiet pump and a seven-day solid state timer allowing up to 14 programmable starts and stops over the 7-day period.
