AF MULTICOLLAR Modular firestop collars for combustible

AF MULTICOLLAR consists of a preformed stainless steel foil which is cut to size on-site according to the pipe diameter. On-site, the foil must be coupled to the AF FIREFILL 50 intumescent sleeve.

AF MULTICOLLAR is used in all compartmentalised sector penetrations of wall and floor plastic pipes, such as sanitary drains, rainwater and vent pipes. It is certified for application on inclined combustible pipes, combustible pipe bundles containing electrical cables and insulated metal pipes.
During a fire, heat causes the intumescent material to expand until it occupies the internal space, ensuring resistance to smoke and flames.
