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 (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.
