Metaloterm MF 87° Bend

The MF 87° Bend is used to create an offset witin the flue system to miss any obstacles such as timber or steel work.  MF is a universal flue/chimney system which is suitable for both high and low temperatures, non-condensing and condensing applications with flue gasses under positive and negative pressure. It is soot fire resistant, therefore the system is suited for a wide range of applications such as boilers, stoves and ovens. The product range also contains a wide variety of silencers.

For Passive houses the assortment provides the Iso-block which can be combined with MF. The system can also be used for CHP applications, in which case a special VITON® sealing ring is used.
Due to its proven quality MF has a 10 year guarantee.
