BWM20W 20′ Four Legged Windmill Assembly with Quick Sink Tubing


Let Mother Nature aerate your pond!

Four Legged Windmill – High Volume Windmill Pond Aerator – Proudly made in the USA!

This windmill tower looks more like traditional farm windmills and is more stable than the three legged units. This unit also pumps a large volume of air and has high pressure capability due to large head size for deeper ponds. One piece welded steel hub secures easily to windmill. Windmill aerators can save $30 to $50 per month in electrical costs, paying for themselves in a few short years.

This kit includes the 20′ Becker Windmill, 50′ of poly tubing, 100′ of Quick Sink Tubing, a dual head Quick Sink Diffuser (QS2) and hinge set (BWHS).
