Entlüftungsrohr

An Entlüftungsrohr, which translates to vent pipe or breather pipe in English, is a critical component in various systems designed to manage pressure and facilitate airflow. Its primary function is to allow air to enter or exit a closed system, thereby equalizing pressure differences. This prevents the build-up of dangerous vacuum or overpressure conditions that could otherwise damage equipment or lead to operational failures.

Entlüftungsrohre are commonly found in fuel tanks of vehicles and aircraft. In fuel tanks, they prevent the tank from collapsing due to vacuum as fuel is consumed or from rupturing due to pressure build-up from fuel expansion or temperature changes. Similarly, in heating systems, especially those with boilers or radiators, vent pipes release trapped air that can impede efficient heating and cause noise.

Beyond pressure regulation, Entlüftungsrohre can also serve to vent harmful or unpleasant gases away from occupied spaces. For instance, in plumbing systems, waste pipes are often fitted with vent pipes that extend to the exterior of a building. These pipes allow sewer gases to escape safely, preventing them from accumulating in the building's interior and contributing to odor issues or potential health hazards. The design and placement of Entlüftungsrohre are subject to specific engineering standards and building codes to ensure their effectiveness and safety.
