Abstract : This invention relates to a portable, sequential air sampler having an easily transportable housing containing therein a plurality of interrelated components which allow the air sampler to operate by either battery or 'line' power as well as maintain the flow rate through the sampling media substantially constant. The components include a vacuum pump and rotary valve which are capable of sequentially drawing air through the sampling media. In addition, a flow rate control system is operably connected to the vacuum pump in order to maintain the substantially constant flow rate through the sampling media. The air sampler can vary initiation of the sampling operation from 1-99 minutes, and, yet, maintain substantially constant air flow throughout the air sampling procedure.
