Aeration, ventilation and draining

The HS^®-Pressure Release Chamber DN/OD 800, that fulfill the specification of the worksheet ATV-DVWK A 157, serves to ventilate and deaerate at high points as well as to drain sewage pressure pipes at low points. The connection of pressure pipelines with an integrated inlet socket is possible up to DN/OD 160. Gravity pipelines can be connected up to nominal diamter of DN/OD 200. Greater nominal diameters are available upon request.

The level invert level of the gravity pipeline lies above the crown of the sewage pressure pipe.The gradient in the chamber channel depends on the nominal diameter of the sewage pressure pipe.

The surfaces of the chamber is smooth, as they are made from PVC-U. Therefore, no deposits are left on surfaces. Especially for the use of the HS- Pressure Release Chamber, the excellent chemical resistance (pH range: 2-12) is of great importance. 

The advantages in practice

• flexible use
• no desposits left on the surface thanks to the smooth surface
• excellent chemical resistance (resistance range: pH 2-12)
