Coarse Bubble Disc Diffuser

We have engineered the Snap-Cap diffuser to be a substantial advancement in the industry. It consists of two simple parts, the support base and a flexible snap-on check diaphragm. The diaphragm is manufactured from a specially compounded, space-age EPDM based, thermoplastic rubber to provide extended life and improved performance. During aeration, the diaphragm lifts from the base, allowing air to exit through its orifices. When the air stops, the diaphragm instantly sits against the base by the pressure head of liquid, preventing backflow and clogging. The novel edge design of the diffuser locks on the removal diaphragm to avoid blow off and unusual pressure surges.
