Cross Section Ventilation



This complete system of an electrical operated shut-off damper, a weight-loaded pressure regulated damper, axial fan and air passage is used to regulate air pressure within tunnel crosscuts and prevents the entering of smoke into escape areas. As designing of the system, selection of the necessary components and installation all come from a single source, this leads to a maximum in operational safety.
