Clyde-Apac is a global brand from Australia that has been operating for over 60 years, focusing on air filtration solutions and contamination control for the industry, healthcare, and science. Their products are exported to over 30 countries and have become a reference for international standards thanks to compliance with the Australian Standard. The company also includes Clyde Filtercorp and Macquarie Engineering since the 2009 merger.

Many of the technologies from Clyde-Apac that are considered global innovations today (such as the dual-fan system in biosafety cabinets) have been implemented since the 1960s—proving that their engineering standards are not only strong but also visionary.
