Terrain P.A.P.A.® & Pleura Vent System

       

 

 


The Terrain P.A.P.A.® (Positive Air Pressure Attenuator) and Pleura Vent System eliminates the need for a traditional piped secondary vent system, meaning that there's no need for vent penetrations in the slab and drastically reducing the requirement for vent penetrations through the roof.

 

By removing the secondary ventilation pipework in commercial, public and high-rise multi-storey buildings, the air admittance system introduces air regulators to balance negative air pressure fluctuations and an air attenuator to balance positive air pressures. Together, they form a highly effective alternative solution for controlling the air movement within the drainage pipework system and soil stack, protecting the water trap seals of appliances within the building.

 

The Terrain P.A.P.A.® is a positive pressure reduction device to mitigate the affects of positive air pressure fluctuations in the drainage pipework system. The Pleura Vent System is an air pressure regulator acting as an air admittance valve, allowing fresh air into the branch pipework or to the top of a waste or soil stack.

 

These systems have been developed to resolve the problems of positive pressures (transients / back-pressure) within the drainage systems and soil stack systems of multi-storey and high rise developments, complementing the use of Air Admittance Valves (AAVs), providing a complete venting solution.

 

The Terrain P.A.P.A.® and Pleura Vent System will only be supplied exclusively with a Terrain Drainage System.
