Self-Aspirating Type Submersible Aerator, JSA-series
The specially-designed star-shaped closed impeller generates negative pressure in the water and draws in air from above the water surface through the air-pipe. Water is sucked through the large inflow port on top of the impeller housing and mixed with the air. This configuration avoids the problem of the inflow port becoming clogged with sediment on the bottom of the tank.
Long service life
The top and bottom internal surfaces of the housing are lined with stainless steel plates. This improves abrasion resistance and suppresses the reduction in air ﬂow performance due to degradation over time.
(Excluding Model JSA15)
The drive motor is of the air-ﬁlled submersible type, which has been highly rated for submersible pumps for many years.
There is no risk of water leakage.
Lightweight and compact
The compact unit is also lightweight. The unit can be easily lifted into and out of the tank.
Easy set up
To get the unit up and running, simply connect the air intake pipe and place the unit in the tank.
Oil change and motor inspection may be carried out while the unit is in its upright position; in short, the product is conﬁgured for easy maintenance.
