O2 Rotor aerators consist of a stainless steel assembly of 12 specially profiled blades arranged radially around a horizontal tubular shaft, driven by an electric motor.

  • High oxygen efficiency
  • Outstanding propulsion capacity
  • Smooth operation
  • Clog-free design
  • Low maintenance
  • Universally adaptable

Accessories which can be added to the brush aerator:

  • flow baffles
  • splash covers
  • drive unit covers
  • hanging construction (for installation under a bridge)
  • splash plates
  • safety railings
  • bridge construction

They are suitable for use in circulating systems and oxidation tanks, and can be mounted on the side-walls of tanks or ditches, or centrally on concrete or steel bridges.

Standard blades are manufactured from stainless steel, which is more resistant to corrosion and provides a longer service-life than conventional galvanised steel blades. The blades are easy to replace should they be damaged by floating debris inadvertently entering the aeration tank.

Both ends of the rotor are supported by self-aligning heavy duty bearing assemblies with re-greasing facilities. The bearing assemblies incorporate a labyrinth type seal arrangement which ensures a watertight construction and facilities to accommodate thermal expansion/contraction due to temperature change.

The standard drive assembly comprises a heavy duty hollow parallel shaft speed reducer with torque arm driven by an electric motor. An alternation option available comprises a separate gearbox and flexible coupling.
