Atlantic Blowers' Diffuser line provides options for optimal performance in any wastewater or oxygen transfer system. We offer both tube and disc diffusers with a fine, medium or coarse bubble option. All of our diffusers use EPDM or silicone membranes which automatically close over the air inlet when the air supply is shut down, which reduces the risk of unintended backflow of water into the air line. Additionally, because water does not sit inside the diffuser, the risk of clogging or fouling is much lower than traditional stone diffusers.
