The fine bubble tube diffuser consists of a membrane support tube made of PVC or ABS and a perforated membrane of elastomeric material, commonly urethane or EPDM.
They are the best option to enhance your existing plant from coarse bubble diffusers.
They are also the best solution in elongated rectangular tanks in terms of mixing since it is easier to create spiral flow patterns.
EDI T Series Flex Air
The EDI FlexAir® T Series Tube Diffuser is a fine pore flexible membrane diffuser capable of providing a high level of oxygen transfer efficiency with maximum operational flexibility.
FlexAir T Series tube diffusers are configured with a premium EPDM rubber membrane sleeve specifically perforated for high volumetric air handling capacity and pressure drop efficiency. For non-standard industrial and domestic applications, alternative membrane materials are available, including urethane, silicone, and other specialty polymers. Alternative perforation patterns are available for energy-sensitive applications or where maximum oxygen transfer efficiency is desired.
The EDI FlexAir T-Series can operate in a wide range of airflows and requires minimal maintenance for long-term performance. The external triple-check valve system minimizes water and solids intrusion into the diffuser unit and air supply tubing under normal operating conditions.
FlexAir T-Series standard diffusers come with factory-assembled, 3/4-inch NPT (male) stainless steel nipples.
