Roto-Type Submersible Aerator

Subair, is a roto-type submersible aerator, made popular for its simple, cost effective means of providing aeration and mixing of wastewater or sludge. Surface air is drawn through a central impeller by the Subairs’ air supply pipe. The powerful impeller infuses together air-water as it accelerates through the impeller and radially discharges the air-water mix through vaned nozzles and releasing fine air bubbles into the tank. Resulting from the high-velocity, radially discharge air bubbles, additional mixing is achieved.

Engineered to rest at a tanks bottom, the Subair submersible aerator 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. This, roto-type, submersible aerator is a perfect solution for both small-to-medium sized tanks and suitable for pre-aeration in sewage and wastewater treatment plants.
