Great Lakes® 1/4 hp Aeration System, Shallow Lakes, w/Cabinet and Two 4-Stone Diffuser Manifolds
The Great Lakes® aeration/destratification system is guaranteed to be the lowest cost method of inducing circulation to remove stratification, add oxygen and deliver the many benefits that result from sufficient bottom oxygen. These systems feature Sweetwater® synergistic airlift diffusers that have proven their effectiveness in over 250,000 acres of lakes worldwide.
Install a Great Lakes® system and be confident that you have the most efficient and effective system available. We have more experience than anybody. For system sizing, contact our Lakes Department for assistance before ordering. One-year warranty. Installation available. Certified to ANSI/UL Standard for Safety, Motor Operated Appliances.
For shallow lakes:
These systems' compressors come factory wired for either 115V or 230V single-phase. Three-phase models, not wired, are also available. Great Lakes® systems feature Sweetwater® oilless rotary vane compressors that include a muffler, inlet check valve, control valves, 0–30 psi liquid-filled pressure gauge and pressure relief valve.
Our shallow lake systems, which use the ALA4GL diffuser manifold(s), are recommended when the majority of the lake is 4 to 8 feet deep. Tubing is not included; we recommend P200 polyethylene tubing on land and WD1 weighted tubing underwater. Maintenance kits nclude four sacrificial carbon vanes, gasket and two inlet filter elements.
Choose either a 100' (P200S) or 400'(P200) roll of unweighted tubing on land. If used in the lake, the unweighted tubing requires tie wraps (T120R) and three-hole bricks (purchased locally) placed every 5–8' to weigh it down. Self-weighted tubing (WD1R) requires no weights, so it takes much less time to install. Both types of tubing can be connected using couplings (101A) and clamps (use SSA for P200 tubing and SSB for WD1R tubing). One coupling and two clamps per connection will be needed. Cabinets can be located a long distance from the lake shore.
We highly recommend using protective devices with all 3-phase equipment. Motor starters, phase monitors and phase protectors are not included in the sale and should be sourced locally. Failure to install protective devices will void most warranties. We also recommend that a certified electrician perform the installation.
