Sri Yantra Clean TechChemical Ventilation
Variable Air Volume Fume Hoods
VAV systems adjust exhaust airflow as the sash moves, aiming to maintain the required face velocity while reducing unnecessary conditioned-air exhaust.
Features and configuration
Responsive control
A sash sensor, controller and modulating damper coordinate exhaust volume.
Airflow feedback
Velocity or airflow sensors and alarms indicate operating conditions.
Facility integration
Controls, fan capacity and room air balance are coordinated during design and commissioning.
Typical specifications
| Control sequence | Sash position → sensor → controller → damper |
|---|---|
| Example opening | 1200 mm wide × 500 mm high |
| Example target velocity | 0.5 m/s |
| Example flow at 500 mm | 1080 m³/h |
| Example flow at 250 mm | 540 m³/h |
| Calculation basis | Opening area × face velocity; minimum flow limits apply |
Applications
- Research laboratories
- Analytical facilities
- Laboratories with variable sash use
Variable Air Volume Hood Operation
The exhaust airflow changes with sash position while the control system maintains the required operating conditions.
