Symmetrical galvanized reducer 160/100 with gasket RSOCU160100

Change of duct diameter without loss of tightness

In mechanical ventilation, a smooth transition between components of different dimensions is crucial to avoid turbulence and excessive flow resistance. The symmetrical reducer 160/100, made of galvanized steel, is a component that enables safe and durable connection of a 160 mm diameter pipe with a 100 mm duct. Thanks to the built-in gasket, the connection is airtight immediately after installation, eliminating the need for additional sealing with tape or silicone. This is particularly important in recovery systems, where even minor leaks can lead to energy losses and reduced efficiency of the entire unit.

Corrosion resistance and compliance with standards

The material used to manufacture the fitting – galvanized steel sheet – ensures long-term resistance to moisture and corrosion, which is standard in ventilation installations. The symmetrical design facilitates installation in hard-to-reach areas, allowing precise alignment of duct axes. Importantly for installers and inspectors, the product bears the "B" mark, which is required for ventilation components placed on the market after June 30, 2019. This means that the reducer meets the rigorous safety and quality requirements set by Polish and EU regulations.

Practical application and ease of installation

This component is suitable not only for new installations but also for modernizing existing HVAC systems where a change in pipe diameter is necessary. Its low weight (approx. 0.21 kg) facilitates transport and work at heights, while the rigid construction guarantees connection stability under vibrations generated by fans.

The fitting is designed as a symmetrical component connecting pipes with diameters of 160 mm and 100 mm. Manufactured from galvanized steel, it ensures corrosion resistance under typical operating conditions of mechanical ventilation. The manufacturer KRZYS-POL supplies the product with a factory-installed gasket, simplifying the installation process and ensuring airtightness immediately after connecting the components. For safe use and regulatory compliance, the reducer bears the required "B" mark, applicable to products placed on the market after mid-2019.

Thanks to its simple design and pre-installed gasket, installing the reducer takes minimal time – simply insert the smaller duct into the larger one and tighten the connection (e.g., using a hose clamp or rivets), obtaining a ready-to-use section of the installation.
