AirGard® Air Velocity Monitor

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, laminar flow hoods, and other enclosures
  • Easy to field calibrate

This flush-mount air velocity monitor allows you to monitor the vertical speed of air inside a cleanroom, hood or other enclosure.

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 or hood. Includes relay output, remote alarm, high flow alarm disable, and emergency purge.
