High speed floating surface aerator

The Aquaturbo AER-AS is a high-speed floating mechanical aerator. It consists of a high efficiency ambient operated motor customized to Aquaturbo wet environment operating standards. The unit is constructed from stainless steel and consists of a one-piece float, a suction cone, and a two flight Archimedes style Screwpeller®.
The Screwpeller® generates a flat and large-diameter spray pattern maximizing the air-water contact zone.
The AER-AS is easily adaptable to nearly any basin configuration. With a lengthened intake cone section, the AER-AS can penetrate water depths up to 8 m. This allows the unit to draw activated sludge of low oxygen concentration from the bottom of the basin to be transformed into an oxygen-rich surface discharge.
Easy to install, robust and reliable, the Aquaturbo AER-AS ensures efficient aeration and mixing for years of maintenance free service.

Various drafts options for suction cones

mIN drafts – STD draft – MAX draft

Each Aquaturbo AER-AS surface aerator has a standard pth suction cone with an associated min and max water level range.

The draft can be reduced or extended within the operational limits of each model. Optimum mixing and oxygen transfer is achieved when the correct draft is selected to suit the water level.
