Air vent DN50/75/110 HL900N

Sewer ventilation device – reliable installation ventilation

This ventilation device, catalog number HL900N, is a key element of any sewage installation. Its task is to ensure proper ventilation, which prevents the formation of negative pressure and unpleasant odors. It is particularly useful in situations where extending the sewage risers above the roof is difficult or impossible. It allows for securing the risers with an air vent, minimizing the need to extend each of them to the outside.

Construction and application

The HL900N ventilation device is designed for use with pipes with diameters of DN50, DN75 and DN110. Compliance with PN-EN12380-1 standard guarantees its high quality and reliability. It is equipped with a removable grid to protect against insects, which facilitates its cleaning and maintenance. A solid rubber membrane ensures tightness and long-term operation. The construction with double thermal insulation limits moisture condensation and ensures stable operation in a wide temperature range – from -20°C to +60°C.

Performance and benefits

High air flow rate, amounting to 37 l/s, is one of the main advantages of this ventilation device. This means efficient ventilation even in more complex installations. Class A1 confirms its high quality of workmanship and durability. Installation is simple and intuitive, which translates into saving time and installation costs. Thanks to this solution, problems related to insufficient sewage ventilation can be avoided, such as slowing down the flow of wastewater or the formation of unpleasant odors in the rooms.
