Natural HVAC Mould, Bacteria & IAQ Control for AS 3666 Compliance

SAN-AIR is an Australian IAQ specialist delivering mould, bacteria and airborne-contamination control for HVAC systems and occupied environments. Its technology uses 100% plant-derived active ingredients formulated into vapour-phase gels, liquids and surface treatments that reduce microbial load and support AS 3666 microbial-control requirements in commercial, healthcare, aged-care, education, hospitality and industrial buildings. Its products are typically applied as part of broader HVAC technical hygiene programs in commercial and institutional buildings.

Capability Overview: https://san-air.com.au/commercial-our-capability/

For consulting engineers, FM teams and mechanical contractors, SAN-AIR provides a low-toxicity, evidence-supported IAQ solution designed for HVAC hygiene, duct and coil microbial de-load, IAQ complaint remediation and risk-based maintenance frameworks.

Core Technology – Vapour-Phase Plant-Based Microbial Control

SAN-AIR’s proprietary plant-derived actives evaporate into a controlled vapour-phase that: SAN-AIR can be deployed alongside UVC ultraviolet light systems and mechanical cleaning as part of a layered HVAC hygiene strategy.

• Contacts airborne mould spores, bacteria and certain viruses
• Reduces microbial viability on air-stream surfaces and dust
• Suppresses regrowth on coils, AHU internals, drain pans and ductwork

Technology Overview: https://san-air.com.au/how-does-it-work/

Independent in-situ testing published by SAN-AIR indicates ≈55% per-hour airborne microbial reduction when correctly dosed.
