LTF Low speed surface aerator

Surface aeration
Surface, fixed or floating slow turbine


Specially designed for wastewater treatment, the hydrodynamic shape of the polyester rotor of the EUROPELEC surface aerator/turbine stirs and oxygenates the water extremely well.


The assembly can be fixed on a concrete gangway or on a metal frame using the seat plate. The very robust slow speed aerator/turbine is designed for use in a fixed or floating position.

LTF is made up of the following elements :

  • A gear motor ;
  • A coupling sleeve ;
  • A rotor, made of fibreglass reinforced polyester, is filled with expanded polyurethane foam. Its density of less than 1 makes it easier to mount in a full tank and reduces the axial loads of the gear motor.


  • A spray cover to avoid aerosol spray and noise pollution
  • A gear motor cover
  • A frame to be adapted to existing civil engineering works in the case of a rehabilitation
  • A wide power range, from 1.5 to 110 kW (more power on demand)
  • French design and manufacturing
  • Option to mount our slow turbines on floating pontoons with or without an access gangway


  • A spray cover to prevent spray and noise pollution;
  • Gear motor casing;
  • A frame for adjusting the existing civil engineering in the case of a renovation project;
  • A suction chimney for deep tanks;
  • Anchoring accessories for the floating version.
  • In its floating version, this product is also available for rental.
