Is VAV System Economical for Fume Hoods?
Fume hoods are essential for safe handling of hazardous substances in the laboratory. But as energy costs rise and sustainability becomes crucial, labs are exploring energy-efficient systems like Variable Air Volume (VAV) technology. At AAKAR Scientific Pvt. Ltd., we specialize in manufacturing advanced fume hoods including VAV-compatible units designed to protect users while optimizing operational costs.
What is a VAV Fume Hood?
A Variable Air Volume fume hood adjusts the amount of exhaust airflow depending on the sash height and occupancy. Unlike conventional Constant Air Volume (CAV) systems that pull a fixed volume of air regardless of need, VAV systems throttle back airflow when the hood isn’t in active use—resulting in significant energy savings.
Is VAV Economical in the Long Run?
Yes and here’s why:
- VAV systems reduce the volume of conditioned air removed from the lab, slashing HVAC costs.
- AAKAR’s VAV fume hoods are engineered with smart airflow sensors and auto-sash options, ensuring efficient energy consumption.
- Though initial investment is higher, long-term reductions in electricity and air conditioning costs make it worthwhile.
- ROI can often be achieved in 2-3 years, especially in multi-hood facilities or 24/7 labs.
- Real-time monitoring of airflow and alerts prevent unsafe conditions.
- Our fume hoods are built with robust airflow controls and safety interlocks.
- Reduced carbon footprint through intelligent air management.
- Supports green building certifications like LEED or IGBC.

When is VAV Not Ideal?
- For smaller labs with limited usage or where the sash remains open for long periods, a CAV system may be more practical.
- However, AAKAR offers hybrid designs that allow easy upgrades to VAV in the future ensuring you stay flexible.
