- Gas Containment Performance
- Prevention of Diffusion from Contaminated Areas
- Credibility and Stability of Research Environment
- Comfortable Air-conditioning
The exhaust and air supply volumes are optimally determined with considerations given to various factors including exhaust volumes of local exhaust systems, the laboratory's minimum ventilation amount, the required air supply volume for air-conditioning purposes, and air balance in the laboratory. This enables both energy saving and comfortable air-conditioning at the same time.

| *1: | Controlled based on the signals from thermostats. |
| *2: | “Good air balance” means, in terms of room pressure management, that the offset air volume between exhaust and air supply volumes is stably maintained at a certain level. |
