5 6 Inch Coarse Bubble Diffusers Wastewater / Coarse Bubble Aeration
5/6 inch coarse bubble disc air diffuser
Coarse bubble diffuser is comprised of the membrane support plate (ABS) and elongation and long service life of Ethylene Propylene Diene Monomer(EPDM).
ABS Engineering Plastic is made from plastic injection molding, it has great corrosion resistance and high-impact performances.
The 12 pores on the membrane of the coarse bubble diffuser are evenly distributed in a circle. The diameter of every pore is 3-5mm, DC board on the support plate can ensure the air which is uniformly distributed in the surrounding, in the meantime, the membrane has a return function, can prevent sewage seeping into the pipeline system.
