The Studor P.A.P.A. (Positive Air Pressure Attenuator) is a revolutionary ‘world-first’ system developed to resolve the problems of positive pressures (transients / back-pressure) within the drainage systems of multi-storey and high-rise developments. This is the perfect complement to the range of Studor Air Admittance Valves (AAVs), providing a complete venting solution for any multi-storey building over 10 storeys high.

Whether you are a drainage system architect or engineer, the P.A.P.A. has changed the design of drainage venting systems, thus allowing building designers to simplify their sanitary waste systems with many benefits.

- The P.A.P.A. provides effective and complete protection against positive pressures in the drainage system, with no specialist installation requirements.

- The P.A.P.A. replaces existing vent piping, which means greater freedom of design.

- The P.A.P.A. has a 10 year warranty for peace of mind.

- The P.A.P.A. can be retrofitted to all types of high-rise drainage designs.

- The P.A.P.A. also reduces the need for fire stopping devices.

The P.A.P.A. has been installed in some of the highest buildings in the world without the need for very large vent pipes.
