Become more successfully self-sustaining with the Outdoor Water Solutions Super Premier Aeration System Windmill. This upgraded version of the Outdoor Water Solutions aerating windmill features upgraded diffusers and a head pivot bearing for more effective operation. This windmill feeds a compressor connected to airlines that lead to the diffusers at the bottom of your pond. The compressor pumps air to the diffusers, which send oxygenated bubbles up from the bottom of your pond. This adds circulation to standing water, which increases its health by fighting scum, algae, and muck. This windmill can be installed in as little as 12 days and has a single-diaphragm system that keeps maintenance simple. The aerating windmill has a 3.04.5 CDM wind rating. Includes windmill with patent-pending BalCam II Technology with stainless steel components, 2 rubber-membrane disc diffusers, one 100' roll of non-weighted airline, two 100' rolls of weighted airline, 2 rubber membrane diffusers with self-sinking bases, head pivot bearing to help swivel windmill head in lower wind conditions, set of tower hinges for easy maintenance, 2-way selector valve for airflow regulations between diffusers, and 2 hose connector packs.
