air tube diffuser


epdm diffuser membrane

EPDM membrane bubble tube diffuser aerator, Blower Aeration System bubble diffuser

Fine bubble tube diffuser for wastewater treatment could be connected on one side or in pairs to different rectangular or round tubes (ABS material) with the appropriate adapters. It could be used intermittently and continuously. The membranes are made of good quality EPDM material or silicone and could produce fine or coarse bubbles. The support tubes (ABS or PVC material) could be reused when membranes are replaced.

The working temperature could be -65 ℃ to 232 ℃, which is suitable for pulp and paper industry, petrochemical and refining process.
