The Pentair Aquatic Eco-Systems Great Lakes® Aeration Systems are complete and ready-to-go packages that include everything you need: lockable heavy-duty aluminum cabinet, efficient rocking piston air compressor and synergistic diffuser manifolds. DA1B comes with ALA4GLB 4-diffuser manifold and unweighted or easy-to-install weighted tubing (see item descriptions below for which is included).
Great Lakes® systems with self-weighted tubing do not require bricks or ties and install much easier and faster than systems with unweighted tubing. To keep from bringing electricity to the lake, the compressor can be located up to 1,000' away with additional P200S tubing.
The sound-reducing, ventilated, weatherproof, heavy-duty cabinet is easily installed on a post, pier or boathouse. Or install on the ground with an additional base (DABASE). Instructions are included, and the entire unit can be shipped Ground. 115V/60 Hz. 230V systems require longer lead time. One-year warranty.
