Sentinel 1/4 HP System / w 100' of weighted airline
For ponds up to approximately 1 acre in size.
Effective aeration can be achieved in 1/4 acre ponds 5 to 8 feet deep, 1/2 acre ponds 8 to 12 feet deep, and 1 acre ponds 12+ feet deep.
The Sentinel 1/4 HP aeration system uses the all new Stratus ERP rocking piston compressor which creates up to 3.5 CFM air flow while drawing 2.5 amps on a 115 volt system. Optional 230v systems are available upon request. Operational costs are approximately 55 cents a day and it can work in ponds up to 50' deep.
The base kit includes the 1/4 HP compressor, 100' of 3/8" weighted airline (we highly recommend the weighted line for durability), and a single EP plate diffuser. All necessary clamps and couplings are included. Need more airline? You can find it here.
**Keep in mind this compressor must be protected from the weather and elements in some way. The kit without a cabinet is fine for use with an existing outbuilding or other protection. Optional packages include a post mounted cabinet (4x4" post not included), and a ground based cabinet.
The deluxe kits include a locking steel cabinet of your choice, cooling fan, accessory electrical outlet, pressure release valve, and a pressure gauge.
By default, this kit comes with a single diffuser, however the compressor is capable of running up to two diffusers as well. This is useful if your pond is oblong or spread out, or very shallow. With the addition of a 2 way valved splitter, a second diffuser, and additional airline, the 1/4 HP system can be expanded to cover more area. You can find the diffuser add on kit in the related products tab on this page.
Includes a 2 year warranty on the compressor, and a 5 year warranty on the airline, diffusers, and cabinet.
