## What does Spiral Aerator include?

The Spiral Aerator draws air down through its spiral tube and drives it into the water with an anti rag impeller, so one unit both aerates and mixes. There is no blower house, no pipework in the basin and no gearbox to service.

It floats on two pontoons and is held by cables to the bank, so it rides up and down with the water level. Units are also kept in a hire fleet, which makes them a good fit for emergency cover when blowers fail or when a lake or reservoir needs oxygen quickly to protect fish.
