The double wall isolated pipes built in AISI-316L stainless steel by Bofill allow the evacuation of combustion products generated by a power unit or by a fire pump.

The part references are the same as those used in the 410 series for diameters of 80 to 300 mm and the 430 series for diameters from 350 to 500 mm, by changing the anchoring system of the modules.  This is a great advantage as it is not necessary to have stock of a different product but rather the parts are the same as those used in the double wall chimneys of the 410 and 430 series.

The module anchoring system is formed by a special flange and seal and is designed to assure perfect closure allowing work at high pressure (H1) and high temperature gases (600ºC) in complete safety.

The anchoring system avoids the thermal bridges and allows the interior wall to expand.  The system also enables fast assembly of the pipes as well as 360º rotation of the elements.

The Bofill modular chimney can adapt to all kinds of interior and exterior building installations with a wide range of diameters and accessories.
