PRODUCTS SERVICES ELECTRO OSMOSIS DEHYDRATORS FINE BUBBLE DIFFUSERS Roeflex FINE BUBBLE DIAPHRAGM DIFFUSERS For over 20 years Roediger ROEFLEX diffusers have been a leader in the aeration industry. Most air diffusers are subject to flooding when the air pressure is turned off. ROEFLEX diffusers have a triple seal mechanism that prevents liquid from entering the diffuser and piping system. ROEFLEX air diffusers will not clog, even if the flow of air is interrupted repeatedly or for long periods of time. The ROEFLEX Fine Bubble Disk Diffuser is a 12' diameter, slightly convex polyamide dish supplied with either a hose barb or a 1/2' NPT connection and is covered by a specifically blended elastic EPDM diaphragm. The diaphragm has multiple slotted perforations sized through extensive design and testing to furnish maximum oxygen transfer at low operating pressures.
