Pond Boss Forums INTRO Questions & Observations Wind Aerator

Notice that the specifications for this unit states that it produces 0.15cfm. Note the mfg is working on a larger wind aerator. This 0.15cfm compares to the 1.0-1.5 cfm maximum air volume produced by the well known Koenders windmill aerator. 0.15 cfm is 10 (ten) times less air volume than the Koenders unit. These air volumes compare to the 3 to 4 cfm produced by the better rotary vane electric air compressors. Amount of air volume produced is very important for proper pond aeration. Always remember that the volume of air (CFM) determines how many bubbles each diffuser can produce. The more bubbles produced and the smaller the bubbles that are produced the more water that is moved by the bubble plume. Moving the water from bottom to top is the main function or purpose of bottom diffused aeration.
