Jet-Type Submersible Aerator


The Subair, jet-type submersible aerator, is popular for its simple, cost effective means of providing aeration and mixing of wastewater or sludge. Combining a submersible pump with a powerful jet-based diffuser, the Subair transfers air in while ejecting an air- water mixture through its forceful jets diffuser. The jets powerful air-water ejection produces a powerful, single, mixing current in the water, creating efficient oxygen transfer.

Engineered to rest at a tanks bottom, the Subair delivers essentially a noiseless and vibration free working environment. These self-standing aerators practically install themselves, simply by using a guide tube or cable attachment to drop to the bottom of either a filled or empty tank. Subair is the perfect solution for both small-to-medium sized tanks and suitable for pre-aeration in sewage and wastewater treatment plants.
