Air diffuser

Air diffuser (DS aerator)

Equipment fixed to the air pipe by welding, which supplies dissolved oxygen (DO) and stirs the content by generating micro-bubbles using the vortex plate and air branch pipes, when air and surrounding water rise together due to the air lift action because air is supplied from the bottom.


No malfunction and good oxygen transfer efficiency.

No blocking and no need for maintenance.


No performance change.

Good stirring and pumping capacity.

Reduced power cost.

Highly cost-effective.

Infrequent maintenance with less malfunctions.

Low-risk operation during maintenance.



The entire area of the tank is stirred uniformly as a circulation flow is formed by the strong jet flow.


Air and sludge are broken into micro particle groups using a Y-shaped cutter forcibly to dissolve oxygen in water.


Mixing air and sludge by forming an intense spiraling flow using a cross-plate.


Forming strong floating pressure inside


Discharging air, and rising from water strongly
