The Studor P.A.P.A. (Positive
Air Pressure Attenuator) was invented by Professor J. Swaffield and
Dr. D. Campbell of Heriot-Watt University, Edinburgh (Scotland) in
close Partnership with  .
The P.A.P.A. is a revolutionary world-first developed to solve the
problems of positive pressures (transients, back-pressure) within
drainage systems of multi-storey developments.
Academic research into
the solution over several years resulted in this intelligent product
- allowing multi-storey building designers to simplify their design
of sanitary waste systems, as the P.A.P.A. - in conjuction with the
approved AAVs - deals with negative AND positive pressures.

The Installation
|
|
The modular units can easily be integrated into the drainage system
design, or retrofitted into an existing installation to solve venting
problems. Together with the AAVs, they provide a complete
protection for the drainage system against the transients, without
the need of costly roof penetration and extensive vent piping.

The
Connection
The P.A.P.A. fits pipe sizes:
- 75mm
- 90mm (remove the rubber connector and replace it with a 90mm
pipe-to-pipe connector)
- 100/110mm
The Testing
This revolutionary product was first tested in the laboratory
of Heriot-Watt and has more recently been installed in several complex
multi-storey buildings in Asia and Australia. The experts are enthusiastic
about the results.
