All components within the ventilation system are engineered to meet the highest safety requirements for laboratory environments. Particular emphasis is placed on gas-tight dampers in both supply and exhaust air systems, preventing any uncontrolled air circulation.
In high-containment laboratories such as BSL-3 and BSL-4, precise pressurization across different zones—including laboratory rooms and sluices—is essential. This is achieved through the controlled regulation of individual supply and exhaust airflows, ensuring that air moves only in predefined directions, a critical requirement for maintaining maximum safety levels.
All airflow is safeguarded by high-performance filtration systems that prevent the spread of particles and microorganisms. Exhaust air is thoroughly purified using H14 HEPA filters before being released into the environment.
