- Gas Containment Performance
- Prevention of Diffusion from Contaminated Areas
- Credibility and Stability of Research Environment
- Comfortable Air-conditioning
Unaffected by fume hoods usage, closing and opening of the doors, and fluctuations in static pressures in the ducts, fume hood's face velocity and room pressure are maintained precisely, thereby ensuring fume hood containment and preventing gas diffusion.
True pressure independence ensures system stability.
In the case where more than one fume hoods are connected to a single duct, when the static pressure in the duct fluctuates due to operation of some fume hoods, containment performance of other fume hoods can be affected.
However, if an Accel II airflow volume control valve is installed for each fume hood, operation of fume hoods does not affect performance of other fume hoods.
It means that gas containment performance of fume hoods is guaranteed while ensuring convenience and safety of researchers.

Accuracy of Accel II Valves
 |
Accel II valves are designed for high accuracy of ±5% (reading) even at low airflow levels, ensuring both energy efficiency and enhanced safety at low airflow levels. |
