The company was founded in 1986 in Austria and specialized in research, manufacture and development of Fine bubble diffusers to the low energy consumption in the aeration works. Aerostrip production technology with membrane diffusers made of 100 percent polyurethane porous diffuser at the time was creating a revolution in the industry. The use of a membrane made of PUR (polyurethane) without the use of lubricants with high porosity main reason lifespan (about twenty years) as well as efficiency is top of the diffuser


Fine bubble diffuser panel


    • Fine bubble production, Standard Oxygen Transfer Efficiency up to 60 %
