Roof inlet body DN75 with vertical outlet and bituminous collar, siphon and internal stainless steel insert HL317KHN

Robust ceiling protection and effective water drainage

This ceiling inlet body, with a diameter of DN75 and vertical outlet, is a key element of the water drainage system from ceiling surfaces. Equipped with a bitumen collar, it provides a tight connection with the waterproofing layer, minimizing the risk of leaks and structural damage. The internal insert made of stainless steel guarantees durability and corrosion resistance, even in harsh operating conditions.

This body is particularly useful during construction investments where reliable protection against moisture and effective drainage of rainwater or technological water is required. The siphon built into the structure prevents the formation of unpleasant odors and ensures hygienic conditions.

Design and application

The inlet body has been designed with ease of installation and integration with various types of ceilings in mind. The bitumen collar allows for precise adjustment to the existing waterproofing, creating a barrier to water. The vertical outlet allows for effective drainage of water to the sewage system. The possibility of supplementing with elements from the HL350 series and caps from the HL66 and HL67 series provides great flexibility in adapting to specific project needs.

High thermal resistance (up to 95°C) means that the inlet can also be used in places exposed to elevated temperatures - e.g. near heating installations or chimneys. A flow rate of 1.6 l/s ensures rapid drainage of large amounts of water, which is particularly important during heavy rainfall.

Advantages and benefits for professionals and users

• Tightness and protection: The bitumen collar guarantees a tight connection with the waterproofing, protecting the ceiling from leaks and moisture.
• Durability and resistance: The stainless steel insert ensures long-term operation without the risk of corrosion.
• High throughput: A flow rate of 1.6 l/s effectively drains large amounts of water, preventing the ceiling from flooding.
• Versatility: The ability to expand with additional elements (HL350, HL66, HL67 series) allows adaptation to different ceiling layer arrangements.
• Thermal resistance: Withstands temperatures up to 95°C - ideal for use in places exposed to heat.
• Easy installation: The design facilitates quick and precise installation on the construction site or during renovations.
• Hygiene: The built-in siphon eliminates unpleasant odors from the sewage system.
