These cut-off dampers are designed for use in comfort ventilation installation, in points of penetration of these installations through vertical and horizontal building partitions. They are installed in systems with increased acoustic requirements.
Fire resistance class: EI120
Strengths:
These cut-off dampers are designed for installation in automatically-activated fire ventilation systems. They support single fire zones, as well as several zones within a single facility. They prevent propagation of fire, smoke and fire gases to the neighbouring zones.
The fans are used in fire ventilation systems for smoke extraction or aeration, they can also be used in ventilation systems as supply or exhaust fans.
These cut-off dampers are designed for installation in general ventilation systems, at the point of penetration of these installations through building partitions.
