The Non-Concentric Increaser Ø 350 from our SWPro series is a versatile flue component designed for expanding your flue system diameter without the risk of condensate pooling. Crafted from high-grade 316L stainless steel, this increaser is suitable for both high and low-temperature applications, including boilers, ovens, and ventilation systems. Its CE marking underlines its compliance with European safety standards.
The modular design features a push-fit jointing system that simplifies installation, while its high-pressure sealing gasket ensures secure connections. It's vital to maintain a 50mm gap between the flue and any combustible materials, and jointing gaskets must be used in both P1 and H1 installations.
