ABS Nopon submersible aerator mixer OKI 2000

The ABS Nopon submersible aerator mixer OKI 2000 is a heavy duty machine suitable for applications in continuous and/or intermittent aeration of both municipal and industrial wastewater. It can withstand many harsh types of wastewater with no performance degradation and will tackle intermittent process problems better than most alternatives.

In the OKI compressed air is distributed through a flexible hose down to the machine. Air enters through the stator and is passed on to the rotating rotor. The hollow rotor wings let air out at the tips. As the rotor sucks water from underneath the machine bubbles of air disperse into the water passing the wing tips. The aerated water exits the machine through the stator tubes ensuring even water and air distribution all around the basin. The low speed rotation ensures that flocks are maintained. The turbulence at the tip of the rotor blades enables high oxygen transfer.

Features

  • Adjustable oxygen transfer
  • Superb pumping capacity
  • Good clogging performance
  • Good corrosion resistance
  • Steady alpha factor
  • Lifetime sustainable high aeration efficiency
  • Especially suited for heavy duty and intermittent processes
  • Easy and quick installation without emptying the tank
  • Liftable for easy maintenance
  • No air cooling in deep tanks
  • Usually delivered complete including suitable air hose, lifting cable and electrical cables making installation safe and easy

The ABS Nopon submersible aerator mixer OKI 2000 series is a natural choice for industrial and municipal applications. The high quality gear motor guarantees performance and long lasting operational life minimizing the maintenance costs.

Product range
