Our Services

Ventilation and indoor air quality around COVID-19

Our air quality and ventilation experts have been supporting industries and organisations since 1973. We’re guided by requirements set out by the ISO, ANSI, ASHRAE and AIRAH, helping create and maintain healthy environments for living, learning or working in. This has become even more important in the wake of COVID-19, and to curb the spread of airborne viruses.

HVAC testing

The performance testing of HVAC systems (air distribution systems) and other building components is key to determining the effectiveness of specific air distribution systems. Vipac’s independent and NATA accredited Air Distribution & Acoustic Laboratory is the largest in Asia-Pacific, with the ability to conduct full-scale mock-ups of various systems. Our services include fan testing, sound testing, testing to a multitude of international standards, airflow visualisation, and more.

Defence and aerospace testing

Our defence and aerospace team specialises in testing and consultancy for the key areas of land, marine, air and space, with security clearances up to NV1. We’ve been optimising the operational performance, reliability and availability of military and aviation assets.
