Energy-Saving & Sustainable

There's no need to supply air during a fire scenario, so frozen supply batteries are not a risk, and the purely mechanical solution cuts costs and environmental impact.

All-Round Protection, In Every Position

Self-actuating cold smoke prevention with the performance of E120S ensures excellent performance in any installation position.

Quiet & Compliant

C-C120 has low noise and leakage and is available in various dimensions for new and existing systems, meeting relevant regulations.

Effortless Installation, Low Maintenance

Its compact design eliminates the need for straight duct lengths before or after installation, offering a reliable, sustainable, and low-maintenance solution.

Protection against smoke spread, cold or hot smoke, occurs by closing the backflow dampers in the event of a change in airflow direction and preventing air and fire gases from spreading through the ventilation system.

C-C120 is tested for ES criteria according to EN 1366–2. It closes instantly when the airflow is interrupted. It is fully self-actuated without any external input, thanks to balanced blades. This ensures reliable and economical smoke protection. It also stays closed in the event of a fire, which generates an overpressure in the affected zone.

To improve the accessibility for inspection of the backflow closure a flexible duct coupling can be used, or accessory for inspection.
