JSA Series


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.

Outstanding features

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)

Time-proven reliability

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.

Easy-to-maintain design

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.
