Welland Store - Air Diffusion Australia

Our Welland store in South Australia opened in 1989 as ADA’s very first branch. Since then, it has grown into a hub of manufacturing and service, with on‑site factories producing both ductboard and sheet metal, supported by a dedicated commercial department.

Across the three Welland sites, 43 employees keep operations running smoothly, and in October 2024 we proudly opened a new trade showroom to showcase our products and expertise. More than three decades on, Welland continues to represent ADA’s commitment to quality, innovation, and customer service.
