The 4-Leg Deluxe kit is the two-diffuser version of our four-post windmill aerator, sized for larger ponds. Splitting the BalCam II compressor's output across two airstone diffusers moves oxygen into two zones at once — the right setup for ponds in the 2–3 acre range or irregular shapes with dead corners. Entirely wind powered: it starts turning at 3–5 mph and produces up to 4.5 CFM.

- 73" galvanized self-governing windmill head
- BalCam II compressor
- 2 airstone diffusers with backflow valves
