Porous ceramic diffusers manufactured by Refractron are a cost-effective and efficient way to inject oxygen and ozone (or other gases) to purify water and treat wastewater. Refractron’s custom, US manufactured, glass-bonded porous alumina diffusers can be configured into the shape of discs, domes, plates or tubes. Choose from our standard AF90 micron pore size for air or AF30 or 50 microns for ozone. We maintain a safety stock of many standard domes, discs and tube diffusers that allows us to respond to unplanned basin and tank maintenance.
Our stock includes our NSF61 certified UNI DISC™ which is designed with an all-ceramic diffuser and resilient stainless hardware to extend longevity and enhance performance in ozone. All our alumina diffuser designs offer excellent strength and corrosion resistance which creates unparalleled durability and longevity even when exposed to harsh cleaning and heavy use.
