AirGard Air Velocity Monitor


AirGard® Air Velocity Monitor

  • Provides constant reading of air velocity for easy monitoring of cleanroom performance
  • Audible and visual alarms let you know when air speed falls below 90 fpm (0.5 m/s) (or other critical velocity)
  • Flush mounts to Terra Modular Cleanroom control panel
  • Easy to field calibrate

This flush-mount air velocity monitor allows you to monitor the vertical speed of air inside a Terra cleanroom.

Its dual setpoint capability enables you to determine critical high/low air speed thresholds. When the air speed exceeds the “safe” range, the AirGard® issues audible and visual alarms to alert you to a clogged filter or other problem. Price includes installation in specified cleanroom.
