Fire dampers

In order to prevent the fire from spreading from floor to floor or ventilation shaft to apartment via the ventilation lines in the event of a fire, firewalls are installed in the uphill sections of the fire. In the event of fire, the cross-section of the pipe, which is 100% free in the operating state, is mechanically hermetically sealed against smoke and fire by a swelling mass.

Design - Fully encapsulated in the metal housing, hingeless fire protection element with a tubular, thermal vent.
Quality - The fire-resistant closure is created by the special intum- essence material WINTU 9.8 erzeugt.
Easy planning - Due to the outlet device built into the firewall, connected ventilation devices or air ducts generally do not require their own fire protection shut-off device.
