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.
