The Non-concentric increaser 2 diameters - Ø 300 is a key component in our chimney flue systems, particularly designed for high-pressure and condensing applications. Its modular design, crafted from high-quality 316L grade stainless steel, ensures maximum durability and reliability. The SWPro system, to which this increaser belongs, is known for its universal compatibility, making it suitable for both high and low-temperature operations, and it maintains a positive and negative pressure seal through its high-pressure sealing gasket P1/H1.This increaser is CE marked and adheres to stringent standards, including EN 1856-1: T200 H1 W Vm L50040 O(50) - Ø 80 to Ø 200 and EN 1856-1: T200 H1 W Vm L50050 O(50) - Ø 250 to Ø 400, ensuring it meets rigorous safety and quality requirements.
Installation is straightforward with a push-fit jointing system, secured by a locking band. It's crucial to fit jointing gaskets at every connection in P1 and H1 installations, and to maintain a safe distance of 50mm from combustible materials.
