Ashirvad Air Admittance Valve – Engineered for Odour-Free Living

When water flows through pipes, it creates negative pressure. Without proper air intake, this pressure can siphon water out of fixture traps—those U-shaped bends that block sewer gases. The Ashirvad AAV balances the pressure, keeping traps sealed and your indoor air fresh and safe.

Absolutely! Ashirvad AAVs are engineered for versatility. Whether it’s a single fixture, a branch line, or a full stack system, they’re ideal for both residential and commercial applications.

Yes! Our AAVs meet rigorous ASSE Performance Standards and are tested to perform reliably in temperatures ranging from 0°C to 60°C—ensuring durability across diverse climates.

Yes, they can! Ashirvad AAVs are UV-resistant and suitable for outdoor use. However, for optimal longevity, we recommend shielding them from direct exposure to harsh weather elements.

An air admittance valve (AAV) allows air to enter the drainage system when required, without the need for a vent pipe extending through the roof. Unlike traditional vent pipes, Ashirvad Air Admittance Valves eliminate roof penetrations, reduce installation complexity, and maintain system ventilation within compact building designs.

An air admittance valve opens automatically to admit air when negative pressure occurs in the drainage system and remains sealed at all other times. Ashirvad AAVs are designed to close securely after use, preventing sewer gases and odours from escaping into indoor spaces.
