Built for property owners who don’t compromise on water quality-or convenience. The Windmill Aeration Base System 4-Leg Tower is your off-grid solution for improving pond health naturally. Designed to serve ponds up to 1 acre and 30 feet deep, this wind-powered system increases dissolved oxygen, reduces excess nutrient growth, and helps eliminate foul odors and stagnant muck-without relying on electricity or ongoing energy costs. 

Featuring our patented BalCam II compressor with stainless steel components, the system delivers reliable airflow starting in just 3–5 mph winds. Fewer moving parts means less wear, less maintenance, and a 5-year compressor warranty that protects your investment long-term.

The base kit includes: 12′-24’ 4-legged galvanized steel tower and windmill head, (1) airstone diffuser with backflow valve, 100′ of non-weighted airline, check valves, and all necessary fittings. Small or Medium Pond Accessory Kit recommended for additional airline, diffusers, and decoy markers. Simple to install. Easy to maintain. Engineered to perform-wherever you need it.
