AF COLLAR C

 

AF COLLAR C is made of stainless steel. The interior contains AF Firefill 50/70/100, a high intumescent power material which is retained by a mechanism. During a fire, the pipe deforms due to the heat and melts until its complete combustion. Meanwhile, the intumescent material spreads and creates a barrier providing thermal insulation and preserving the floor or wall "separating" function of the element for at least 180 minutes.

 

AF COLLAR C is a special fire protection element for combustible pipes suitable for curved or branched pipes adjacent to walls/floors where it is impossible to apply normal firestop collars.

Its “C” shape avoids the need for calcium silicate protection boxes, which are more complex and expensive due to their long construction times.
