FLUE PIPES COAXIAL
The COAXIAL system is composed of single wall elements with circular section and it is suitable for outdoor installations and condensate boilers. It resists to corrosion and its maximum operating temperature is 120°C.
Each product is composed of two concentric single wall elements. The inner wall is manufactured in self-extinguishing plastic polymer, PPs, while the outer wall is manufactured in stainless steel AISI 304 with BA shining finish and longitudinal plasma welding.
All elements have a male-female socket and a seal. Locking bands (supplied on demand) ensure mechanical tightness.
The COAXIAL system allows both fume evacuation, through the inner PPs wall, and air aspiration, through the gap between the inner and the outer wall.
