Aquarius - Model EPDM -Low Pressure Disc Diffusers
Constructed of the same advanced EPDM membrane blend as the Standard Membrane Disc Diffuser, the Low Pressure Disc Diffuser provides a unique perforation pattern with lower headloss as the membrane gradually expands when air flow increases. EPDM Low Pressure Membrane Disc Diffusers are capable of operating over a wide range of air flows while maintaining consistent oxygen transfer efficiency. The same effective integral check valve utilized on the Standard Membrane Disc Diffuser prevents back-flow and is a great choice for intermittent operation. The EPDM Low Pressure Disc Diffuser is suitable for heavy solids, aerated mixing, and industrial applications requiring high air flow rates and can be utilized in EPDM Standard Membrane Disc Diffuser applications to meet lower headloss requirements.
