Mounting & Installation

The AirSafe PM is designed to be used indoors only. It can be installed in any room that needs particulate
monitoring as part of exposure and health safety limit monitoring.

The AirSafe PM can be easily mounted to most surfaces and areas, such as:

  • Process areas
  • Storage rooms
  • Laboratories
  • Breakrooms
  • Changing rooms
  • Office areas
  • Other footfall areas of health and safety exposure concern
  • Areas of air quality monitoring requirements

Install the AirSafe PM as near as possible to air intakes, areas of air movement, and areas of static air/settlement where people work. When positioned near the ventilation and filtration apparatus, the AirSafe PM can be used to monitor the effectiveness of the ventilation and filtration process.
