Fine-Bubble Membrane Disc Diffusers
The Oxi-Pro membrane disc diffusers come in two model types: Model RCD and RSD. Both models are engineered to supply powerful self-cleaning capabilities and designed with innovated positive check systems, enabling the membrane to stop backflow immediately on blower shutdown. These diffusers are ideal for air-on / air-off and seasonal applications. Both models are available with built-in check valves for frequent on / off applications. The Oxi-Pro line also offers a Coarse Bubble Membrane Diffuser.
OXI-PRO Membrane Disc Diffusers mount on any pipe material including, but not limited to: PVC, ABS, CPVC and SS. Mounts on any pipe size with a universal diffuser mount or using a standard 3/4” female connection.
Operates with a double membrane that packs over 6600 perforations. These perforations create extremely fine, uniform bubble patterns creating optimal oxygen transfer. This diffuser holds up to the most demanding operating conditions, with a membrane made of chemical resistant EPDM material and a polypropylen housing. Designed and engineered with a integral check valve design, using a separate snap-cap diffuser at its base, the RCD prevents any back flow to enter back into the housing, even while the main membrane is still closing or collapsing.
Operates with a single membrane, the RSD offers a slightly lower pressure drop then the RCD, but delivers equal oxygen transfer efficiency. Made with high-strength, corrosion-resistant ABS plastic, it delivers the same quality type membrane as the RCD. Designed and engineered for self-cleaning, using a molded diffusing membrane which creates a flat sealing surface at the center of the diffuser, the RSD prevents any back flow to enter back into the housing.
