Air Inlet and Outlet with Emergency Overflow, DN 100

Vent and Drain Valves for Safe Pressure Equalization & Reliable Emergency Drainage

The vent and air release valve with DN 100 emergency overflow ensures reliable air equalization in tanks, pipelines, and infiltration systems and effectively protects the system against overpressure or underpressure. If the maximum water level is exceeded—for example, during heavy rain— the component also functions as an emergency overflow to ensure safe drainage.

The vent and air release valve is typically installed at the end of an infiltration system and is usually discreetly located outdoors, e.g., in a hedge or flower bed. To ensure that (rain)water can flow smoothly into the system, a controlled air outlet must be ensured elsewhere.

To achieve this, a DN 100 KG pipe is installed behind the system, which safely directs the air to the surface. The vent is the terminal point of this line and is designed to reliably prevent animals from entering.

Sustainability

The product is made of durable, single-grade, and fully recyclable polypropylene. The material is long-lasting, environmentally friendly, and chemically inert—it has no impact on the environment.

The production and recycling of this plastic are carried out in a resource-efficient manner. Responsible use in line with the circular economy is, for us, a central component of sustainable action.

Notes

The vent should be inspected once or twice a year to ensure consistently reliable operation.
