They are intended for installation in general ventilation installations. It is possible to make dampers in the ex version.
Fire resistance class: ei120
Strengths:
Blast ventilation systems are used to smoke off underground garages as an alternative to traditional duct systems. All devices included in the mcr j-FLO system are approved for use in construction in fire protection.
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.
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.
