FEATURES AND BENEFITS

  • Controlled and self-monitored system
  • Calibratable alarm
  • Prevents creation of dust explosion zone
  • Concentrations in the ambient air are safely monitored
  • AirSafe can be used as early detection for dust which could endanger the workplace
  • Adapted for applications in zone 22 dust
  • Possible dust leakage from the process is quickly detected
  • Monitors dust concentrations on the basis of pre-set limit values
  • Can be used as early detection of particulate concentrations which could endanger the workplace

 

MOUNTING AND INSTALLATION

AirSafe 2 can be installed anywhere in a room.
Except for high ambient temperatures, there is no need to maintain distances from units or walls.

AirSafe 2 can be wall-mounted using the brackets provided.
