We have always loved the plate style diffusers from Easy Pro. Now they come with a self weighted base for easier deployment.

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 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 bubble rise to the surface and create circulation that helps destratify and aerate the water body.

The base has a powder coated finish.

Built in check valve to prevent water backing up in the airline.

Includes inlet air fittings to fit 3/8", 1/2", or 5/8" airline.

Available in a single plate or two plate design.
