T-series Tube Diffusers


FlexAir T-Series Tube Diffusers are generally chosen in applications with high airflow requirements, and/or in harsh wastewater environments.  They are available in liftable or fixed grid configurations and they are manufactured from high quality materials to suit all process operating conditions and wastewater types.


T-Series Tube Diffusers have a premium quality EPDM rubber membrane sleeve, specially perforated for high volumetric air handling capacity and headloss efficiency. Alternative membrane materials such as polyurethane, silicone, and other specialty polymers are available for industrial and aggressive effluents. Several perforation patterns are available to suit efficiency and headloss needs.  With a variety of diffusers, membranes and perforations to choose from, Corgin can help design your system to operate at maximum efficiency and peak performance.

These diffusers are available in 62mm and 91mm diameters and withlengths from 250mm to 1000mm to cover a wide range of flow rates and floor layouts. They are available as saddle mounted or threaded units.
