The Non-concentric increaser - Ø 175 is a vital part of the SWPro modular single-wall flue system. Made from high-grade 316L stainless steel, this increaser ensures longevity and durability in a variety of applications, including boilers, ovens, ventilation systems, and chimney shaft liners. The flue system boasts a high-pressure sealing gasket P1/H1, making it suitable for both high and low-temperature settings, as well as non-condensing and condensing environments with flue gases in both positive and negative pressures.
This increaser seamlessly transitions to a larger diameter while preventing potential condensate pooling, thanks to its unique design. Installation is a breeze with the push-fit jointing system and Locking Band, ensuring secure connections. The SWPro system is CE marked, with designations EN 1856-1: T200 H1 W Vm L50040 (Ø 80 to Ø 200) and EN 1856-1: T200 H1 W Vm L50050 (Ø 250 to Ø 400).
