Design and Specifications/ USP


Suitable for High-rise buildings

The sheer height of a building changes the physical forces applied to plumbing systems, rendering conventional designs unsuitable for the job. In a high-rise building, our well-designed drainage systems operate at maximum efficiency with trap seal protected.


Resolution of Transient Pressures

Our active drainage ventilation systems are revolutionary ‘world-first’ systems developed to troubleshoot the problems of transients and back-pressures occurring inside complex drainage systems of high-rise buildings and multi-storey complexes.


Replaces Conventional Vent Piping

Ashirvad Active Drainage Systems are a part of a total pressure balance system that replaces existing vent piping, which enables greater freedom of design. Our systems are put in place effectively to eliminate foul smells, unpleasant noise and prevent repeat maintenance.


Provides relief at the Point Of Need (PON)

Our Active Drainage systems manage an efficient mix of air and water. Our innovative design provides relief at the Point Of Need (PON) by eliminating an incoming pressure transient that can lead to trap seal depletion.

Why Ashirvad Active Drainage Ventilation System?

Ashirvad P.A.P.A drainage system for modern residential high-rise buildings and commercial complexes

Prevent loss of Water Seal

Ashirvad Active Drainage Ventilation Products prevent the loss of water seals in traps, and hence bad odours. Maintaining optimal water seals across all traps at all levels in a multi-storey building upholds the highest degree of health and sanitation for inhabitants.

Maintaining Air Pressure

Ashirvad Active Drainage one-way vents protect the trap seals in the drainage system by regulating the accurate intake of air, so that optimal pressure level within the drainage system is maintained. Our patented design guarantees a lifetime performance on quick opening reaction time, zero maintenance and a 100% closing ability that meets all leading international product standards.

Reduced Roof Penetrations

Ashirvad Active Drainage Ventilation systems minimize roof penetrations and expensive structural adjustments that are typical of most drainage retrofit installations. Lower cost of installation and better usable life make our products the preferred choice among all developers.

Retro-fit applications

These systems can be retrofitted to all types of high-rise drainage designs. Ashirvad has an impressive range of solutions that can be accommodated within any architectural drainage system, for new and old buildings alike.
