Flonox Stainless tundishes / tundish products. A tundish creates an air gap between a combi steamer oven and the drain. With the Flonox range of tundishes, they are compact enough to be installed higher off the floor, allowing enough room to connect either into the existing kitchen drain network or using adaptors for a fresh install in push fit drainage.
