Quick Sink, self-weighted membrane air diffuser assemblies are designed to be placed at the bottom of a pond or lake. The self-weighted design eliminates the need for gravel and reduces installation time. The Quick Sink diffuser assembly features round rubber (EPDM) membrane diffusers with thousands of holes which produce small air bubbles when supplied with air from an on shore compressor. These bubbles rise to the surface and create circulation that helps destratify and aerate the water body.
