Shut-Off Dampers HID

Universally usable dampers in lightweight design, which are used for all air-related applications within rail tunnels as well as escape tunnels and technical shafts. Due to their modularity in design and assembly as well as their flexibility in location of actuators, those dampers open a wide range of applications.
