Two Outlets with Gast Compressor The Atlantic Water Gardens two-outlet cabinet aeration system provides a commercial-grade Gast diaphragm compressor in a weatherproof outdoor enclosure with two independently controlled air outlet lines. This configuration lets you run two diffusers in different areas of your pond simultaneously, improving oxygen distribution and water circulation throughout a larger water body than a single-outlet system can serve. Two Zones, Flexible Placement With two outlets, you can place one deep-water diffuser for destratification and one shallow diffuser near the pond shelf where fish congregate, or run separate diffusers at two ends of a long, narrow pond to create a consistent circulation loop. Each outlet includes an adjustable valve to balance airflow between diffusers. The Gast compressor's continuous-duty rating ensures both outlets receive a steady supply even at maximum output year-round, including through Canadian winter freeze-over.
