Air velocity control unit VAV-CI-4.3

for fume hoodswith touchscreen

Product overview
TopAir’s advanced VAV system measures the product’s air velocity using a high quality sensor and adjusts the air velocity to the relevant standard. The system enables maximal energy savings by flexibly adjusting the fan speed (high/low) to changing needs. Reduced fan speed also reduces HVAC load and the fume cupboard's noise level.

Function & operation
The system keeps the user updated on airflow speed at all times and provides alerts on deviations from the required speed to prevent hazardous situations. The VAV system is delivered as an integrated, configured and programmed plug-and-play solution, combining control, user interface and frequency inverter into a single turnkey system. The VAV system can be used to renovate an existing fume cabinet or installed in a new fume cabinet to upgrade it into an intelligent system.

What the VAV system comprises

• A touch screen including visual and audio indicators for alerts, and a mute button.
• A unit including sensors and power supply for the screen.
• VFD (Variable Frequency Drive) which controls the frequency and voltage supplied to the motor.

Applications
Made in the USA, the VAV system is a reliable and user-friendly solution for setup and use. The system can be installed in research laboratories, healthcare facilities, life sciences companies, universities and similar environments.

Features

• 4.3" or 7" color touch screen with display and control for set point, air velocity, alerts and configuration information.
