Product Description

The Rubber Membrane Tubular Air Diffuser is an ideal addition to a pond aeration system to oxygenate and circulate the water in your pond or water garden. The increase in dissolved oxygen improves water clarity and quality, and the circulation makes water temperatures in the entire pond more uniform. These improvements help koi fish and other aquatic life. To operate, this diffuser must be connected with tubing to a compressor (air pump).

Pump and tubing are not included. 

This EPDM rubber tubular air diffuser is available in different lengths. Each diffuser is 1.5 inches in diameter. Models with barbed inlets feature multiple sized barbs, which can be cut to fit the air line tubing.
