What pond size is this built for?
This windmill can effectively aerate ponds up to 2–3 acres, depending on shape, depth, and which base/tower configuration you choose.
Should I choose the 3-leg or 4-leg base?
The 4-leg base offers a wider, more stable footprint suited to larger ponds, while the 3-leg base is a solid choice for ponds up to about 1.75 acres.
How much wind does it need to run?
It operates effectively in winds as low as 3–5 mph, and the 24 ft tower option helps capture more consistent wind in lower-wind areas.
Do I need electricity to run this?
No — it's a fully mechanical, wind-powered system. Wind drives the compressor directly, with no electrical hookup required.
How long does installation take?
Most installations are completed in one to two days, so your pond can start benefiting almost right away.
What's the warranty?
The compressor is backed by a 5-year warranty, with a 1-year warranty on the rest of the system.
