The Non-concentric increaser - Ø 500 by SWPro is a top-grade modular single wall flue system made from 316L stainless steel. This increaser is designed to elevate one diameter while preventing potential condensate pooling, making it ideal for inclined runs. With its robust construction and high-pressure sealing gasket P1/H1, this component is suitable for high and low temperatures, and both non-condensing and condensing applications.
Perfect for boilers, ovens, ventilation systems, and as a chimney shaft liner, it offers unparalleled versatility. The CE-marked SWPro system ensures compliance with rigorous standards and features a user-friendly push-fit jointing system secured by a locking band. For P1 and H1 installations, jointing gaskets must be used at every joint, and a 50mm clearance from any combustible material is mandatory.
