Aquatic Eco-Systems

Great Lakes® Aeration Systems, Deep Lakes

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 deep lakes:
Compressors are factory wired for either 115V or 230V single-phase. Three-phase models, not wired, are also available. Deep lake systems use our ALA6GL diffuser manifold(s) intended for lakes deeper than 8'. The compressors can be mounted in an optional vandalproof, lockable cabinet that will also keep out the weather. The cabinet is made of 1/8" thick steel and painted avocado green to blend into the surrounding landscape.

Cabinets include built-in cooling fan(s), lock(s) and soundproofing that keeps the noise level below 55 dB (normal conversation) at 10' and virtually inaudible at 50'. Cabinets come mounted on a lightweight equipment pad that is suitable for private installations. The cabinet can be bolted to a concrete base (for public installations). Tubing sold separately due to the variation in lake sizes.

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 (ask the Lakes Department for guidance).

3-Phase Equipment
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.
