Floor inlet DN50/75/110 vertical with connection flange, siphon, plastic frame 123x123mm and stainless steel grating K3-300 kg HL310N

Floor inlets – reliable drainage in every building

This vertical ceiling inlet DN50/75/110 with a connection flange is a versatile solution for water drainage, ideal for both professionals and building owners. Equipped with a siphon, a plastic frame with dimensions of 123x123mm and a durable stainless steel grating (load class K3 – up to 300 kg), it provides effective and long-lasting drainage. The design of the inlet allows for height adjustment of the base in the range of 12-70mm, which facilitates adaptation to different floor layers.

Design and application

The inlet has been designed for easy and tight connection with the waterproofing layer, thanks to the use of a sealing kit from the HL83 series (available separately). Its versatility results from the possibility of connecting drains with diameters of DN50, DN75 and DN110 – this is a practical solution that eliminates the need to have several different models on the construction site. The built-in water trap effectively prevents unpleasant odors from the sewage system from entering. In addition, the inlet is resistant to high temperatures (up to 85°C), which increases its durability and range of applications.

Advantages and benefits

• Versatility: The ability to connect drains of different diameters (DN50/75/110) simplifies installation and reduces the need to have many types of inlets.
• Tightness: The connection flange combined with the HL83 sealing kit guarantees a tight connection with the floor waterproofing, minimizing the risk of leaks.
• Durability: The stainless steel grating with load class K3 (up to 300 kg) provides resistance to mechanical damage and long-term use.
• Height adjustment: Adjustable base height (12-70mm) makes it easy to adapt to different floor thicknesses.
• Prevention of unpleasant odors: The built-in water trap blocks access of air from the sewage system to the interior.
• Expandability: Compatibility with simple and collar extensions (HL340N, HL85N, HL85NC, HL85NH) allows you to adapt the drainage to specific conditions on the construction site.
• Efficiency: A flow rate of 0.67 l/s ensures efficient water drainage.

This inlet is not only an installation element – it is an investment in comfort and safety of building use. Its solid construction and well-thought-out solutions make it a reliable solution for any construction project.
