Submersible Ejector J/JA/JF/JAF
High Performance with Low Power Consumption
SHINMAYWA helps to cut initial and running casts.
For preliminary aeration of industrial wastewater treatment plants etc.
Submersible Ejector forces sucked air into the tank through an ejector action with a jet of water,thereby stirring the liquid in the tank simultaneously. Since Submersible Ejector offers high performance and low power consumption, it allows you to cut initial and running costs. It can be used efectively for the preliminary aeration of purifying tanks etc. Submersible Ejector is available in two types: the automatic connection type and free-standing type. You can choose either according to your application.
Major Features
– Stirring with a jet of weter and tiny air bubbles ensures uniform MLSS concentration in the tank.
– Low noise generation.
– Since Submersible Ejector can be used in water from 1 to 6 m in depth, limted treatment areas can be efectivety covered.
– Submersible Ejector has a long life thanks to a vortex type impeller, which allows foreign matter to pass though easily.
– Submersible Ejector, especially the automatic connection type, is easy to maintain.
