AF COLLAR C

AF COLLAR C is a special fire protection element certified under EN 1366-3 for up to EI 240 protection of combustible pipe penetrations with bends or branches adjacent to walls/floors.
AF COLLAR C consists of a stainless steel case and intumescent stripes (AF FIREFILL 50/70/100).
In case of fire, due to the action of heat, the combustible pipe suffers a deformation and melts gradually while the intumescent part of the AF COLLAR C expands and blocks the passage of smoke and flames.
The particular “C” shape avoids the need to manufacture ad-hoc structures made of calcium silicate or gypsum slabs. ETA 16/0772
