Four Outlets with Gast Compressor

The Atlantic Water Gardens four-outlet cabinet aeration system is the most comprehensive single-cabinet aeration solution in the Atlantic lineup — a commercial-grade Gast compressor in a weatherproof outdoor enclosure with four independently valved diffuser lines. Designed for large ponds, commercial installations, and koi keepers with high fish densities, this system maintains dissolved oxygen throughout even the most demanding water body.

Maximum Coverage from a Single System

Four independent outlets allow precise placement of diffusers at the deepest point, in multiple fish congregation areas, in dead-zone corners, and near any filtration zone that benefits from additional circulation. Individual adjustable valves on each outlet make it straightforward to fine-tune air distribution as seasonal conditions change — more flow to deep zones in summer, redistributed to surface zones in winter to maintain ice-free areas for gas exchange across Canada's coldest months.

How to Use

Mount the cabinet above the waterline in a secure, accessible outdoor location. Run four independent lengths of weighted airline tubing to strategic diffuser positions throughout the pond. Balance each valve to match the volume and fish load of each zone. Connect to a GFCI-protected outdoor circuit. Annual maintenance: inspect and replace the compressor diaphragm and filter as needed to maintain full output.

Ideal for commercial koi facilities, large residential ponds over 50,000 L, and any installation requiring four-zone year-round oxygen management in Canada.
