Product description

High performance

A special depressurised turbine rotating at 3000 rpm is attached to the motor shaft extremity. The air coming through the guiding tube is sucked into the propeller centre by the VENTURI effect. The air mixed with the water is diffused in the water stream in micro-bubbles and directed to the pond depth. The quantity of transferred oxygen is optimal as the micro bubbles have a very long lifetime in the pushed water volume.
