  • Page 3: Introduction

    INTRODUCTION The SKC AirChek 20 Sample Pump (Figure 1) is a portable and programmable pump for high flow air sampling. With a flow range of 4 to 20 L/min, it provides high-performance sampling for asbestos and other particulates. AirChek 20 is ideal for area and environmental monitoring, bioaerosol sampling, and long-term background monitoring.

  • Page 12: Operation

    OPERATION Sampling • Allow pump to equilibrate after moving it from one temperature extreme to another. • Charge pump battery completely before setting and verifying flow rate and sampling. After setting/verifying pump flow rate, replace the representative sampling medium with a new unexposed sampling medium for the sampling train (Figure 4).
