High speed floating surface aerator

Axial flow aerator with patented instantaneous radial discharge. World renowned for high aeration efficiency in field conditions due to maximum transfer of kinetic energy to water surface.
Installations range from small tanks to large lagoons due to high mixing and oxygen dispersion characteristic in the form of an apple shaped flow.

High efficiency motor






Adaptable depth suction cone


Anti-vortex and stabalization cross


Protection and lifting motor bracket

  • Soft-edge liner base
  • Large stabilisation cross
  • 100% Stainless steel construction
  • Anti-erosion plate

  • Alternate materials of construction – AISI 316L stainless steel; duplex stainless steel upon request
  • Special cone-cross options to suit application -e.g., flow through design for oxidation ditch with varying flows characteristics
  • Alternate WEG paint plans and colours upon request
  • WEG W3Seal* with brass labyrinth seal for ultimate ingress protection
  • Tropicalised Windings Internal paint system
  • Centered tube for liner protection 
  • Anti-erosion plate
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.
