ROKU® System AWM II

The ROKU® pipe collar AWM II or AWM II Light up to 240 minutes fire rating for combustible pipes up to pipe outside diameter 400 mm consists of a solid metal sleeve which is equipped with several layers of the high performance intumescent material „ROKU® Strip“. In the event of a fire, the intumescent material expands with a high pressure and thus seals the opening hermetically against flames and smoke. For wall installations one pipe collar on each side of the wall must be provided, for floor installations one pipe collar on the underside of the floor.
