Nanrong paddlewheel aerators have been tested by American Society of Agricultural Engineering (ASAE) and University of Hawii,and the velocity of oxygen dissolving is excellent. After using NR-121 for only 32 minutes, the dissolved oxygen area can reach 8PPM. After using NR-122 for 25 minutes it will reach 8PPM. And it will provide 4.99KG oxygen per hour.

CHARACTERISTIC OF NR AERATORS |
|
|
|
* Super high efficiency: stronger water current,perfect oxygen dissolving velocity.
* Lower aquaculture cost: saving electricity, durable, and easy maintenance.
* Multifunction: suitable for varied aquaculture such as shrimp,eel,crab,algae. |
