OVERVIEW

FlexAir Disc Diffusers

Corporate Responsibility

Rising energy costs and a global drive to reduce carbon emissions make us all responsible to ensure that equipment is as energy-efficient and performance-optimised as possible. It is for this reason that Corgin offer design optimisation to match diffuser performance curves with aeration blower ‘sweet spots’.

Advanced Membranes

FlexAir Disc Diffuser membranes incorporate advanced technologies for superior aeration performance and reliability. They have an integral triple check valve to prevent backflow of wastewater into the diffusers and piping. Membranes can be manufactured using EPDM, PTFE (Teflon), Silicone, Viton and Polyurethane, with both laminated and coated options available for superior long-life performances. A number of perforation options are available to optimize pressure drop and oxygen transfer efficiency.

Range of Sizes

These diffusers are available in 7″ (178 mm), 9″ (230 mm), 12″ (305 mm) diameters. The 9” diffuser is also available with premium quality ceramic diffusers, suitable for continuous aeration applications where maximum asset life is required.
