EasyPro's QS1 Weighted Diffusers are designed to be placed at the bottom of the pond to provide aeration and keep your pond healthy. Features an EPDM rubber membrane with thousands of holes which create air bubbles when used with an on-shore air compressor. This air rises to the surface and provides circulation and aeration, which helps to destratify the water. 

This diffuser is self weighted, with a powder-coated steel base and includes stainless steel hose clamps and inlet air fittings. This diffuser accepts 3/8", 1/2", or 5/8" tubing. Features an acceptable airflow range of 0.8-3 CFM or 22.7-85 LPM.

This diffuser is backed by a 5-year manufacturer's warranty.
