Dual Diaphragm Windmill Aeration System

In stock
IP A 39013

20' Windmill aeration system designed to use the power of the wind to pump life-giving oxygen into your water.

The dual windmill is adapted for larger ponds, or moderate wind conditions, and can run up to three airstones off a single unit. It can transfert up to 50,000 cubic feet of oxygen per month into your water.


  • 20' windmill (color: grey/galvanized)
  • 1 x dual diaphragm compressor
  • 200' of 3/8'' airline polytubing
  • 2 x airstone diffusers
  • 2 x foot valves
  • 1 x 2-way selector valve


  • Crankshaft and Bearings: 1'' turned, ground and polished steel crankshaft. Long lasting, heavy duty and durable sealed bearings.
  • Streamlined, large-surface blades: Engineered for the most efficient operation in low and high wind speeds.
  • Durabale and efficient diaphragm: Allows windmill to save energy while still producing maximum air volume and longevity. Allows optimum performance in winds as low as 3-5 mph.
  • Large tail: The large surfaced tail area provides maximum control in all wind speeds and ensures efficient overall operation.
  • Strong tail arms: Tail arm rigidity further ensures windmill control.
  • Top mounted compressor: Connected through a rigid pivot tube, providing smooth operation and mechanical longevity. The top air valve assembly makes for easy maintenance.
  • Tower design: The strong cross brace reinforcement design gives added strength to the tower. This design also discourages climbing of the tower.
