Normal Pressure Ranging – 0 ~ 80kPa Aeration systems perform two functions simultaneously: The low speed aerator designed for optimum stirring and oxygenation of sewage water is particularly used in fixed version The solidly-built components have been selected to guarantee a long life with a reduced maintenance. The solidly-built low speed turbines consist essentially of a rotor attached to a geared-motor by means of connecting shaft. Thanks to a flask incorporated into the geared-motor, the whole unit can be fixed on a concrete walkway or a metal framework. Oxygenation efficiency Efficiency between 1.6 and 2.4kgO2/kWh depending on operation conditions. Power Ranging from 2.2kW – 55kWANLET Blower

The HYDRO-CHEK air diffuser is the result of an extensive research and development program. It combines simplicity of design and operation with quality construction to provide efficient, economical and trouble-free aeration throughout new and existing water treatment systems.
The Patented ‘down-flow’ design puts air flow orifices in the diffuser body, not in the air check diaphragm. It also preserves the diaphragm’s structural integrity for significantly extended diaphragm life and eliminates the problems caused by sediment that could otherwise settle in diaphragm orifices. This down-flow design also maximizes the shearing of the air bubbles as they emerge from the orifices and turn upward around the perimeter of the diffuser.
The HYDRO-CHEK air diffuser uses the positive action of the flexible air check diaphragm to prevent backflow. The diaphragm distends during aeration to allow air through the diffuser body orifices. When the airflow is stopped the diaphragm instantly contracts and is force seated against the diffuser body by the water pressure in the tank. In this closed position, liquid backflow is prevented from entering and clogging the diffuser or air manifold.
