Aqualung Group (formerly Aqua Lung International, and prior to that La Spirotechnique)[1] is a manufacturer of self-contained breathing apparatus and other diving equipment. It produced the Aqua-Lung line of regulators, including the CG45 (1945) and the Mistral (1955). From its founding in 1946 until 2016, the company was a division of Air Liquide. The company was sold to Montagu Private Equity in 2016,[2][3] and subsequently acquired by Barings LLC in 2023.[4]
