FUME HOOD ACCESSORIES
Cava™ can take advantage and multiple fume hood accessories to
effectively monitor and control fume hood face velocity, reduce
energy consumption, and keep work environments safe.
Fume hood accessories provided by Antec Controls include:
1.
Fume Hood Valve Module (FVM) - Venturi Valve (VV) Applications
2.
Fume Hood Valve Module (FVM) - Venturi FX Valve (VFX) and
Terminal Unit (TU) Applications
3.
Sash Position Sensor (SPS)
4.
Sidewall Velocity Sensor (SVS)
5.
Fume Hood Presence Sensor (FPS)
Fume Hood Valve Module (FVM) - Venturi Valve (VV) Applications
The Fume Hood Valve Module (FVM) works directly with Cava™ to accurately meet
the required exhaust airflow and fume hood face velocity. The FVM used in Venturi
Valve applications uses calibrated position feedback to provide accurate airflow
through the valve and provides real-time differential pressure readings to ensure the
valve remains within its operating parameters at all times. The FVM delivers this
real-time airflow device information to Cava™ for display and communication over
CANbus.
