ECOWATERCHINA aerator rubber hose D25 for shrimp ponds talapia , lake irrigation ,Aquaponic systems.

Nano-Tube creates important breakthrough in 

oxygen diffusion aeration technology in the water.

Used to make the dissolved oxygen in the water reach higher amount and enhance the stocking density. Apply to aquaculture, sewage treatment, garden irrigation, greenhouse grow.

Product performance parameters:

 Outer Diameter: 10 to 28 mm
Wall thickness: 2 mm above
The bubble diameter: 20-50 um
Dynamic power: 02 / kw. Hr
The air flow: 3-12 cubic meters/HRM
Applicable water depth: 0-6 meters
Vortex air pump: effective water depth about 1 meter , housed density 1-2 times improve.
Centrifugal pump: effective water depth about 2-3 meters, stocking density improve 3-4 times.
Cottonwood ROM watts fan: effective 3-10 metres above water depth, the effective length can reach 300 m, stocking density can be reached 3-6 times.
Note: no matter you use which kinds of models of air pump, and the pipe section sum is not greater than the total area of main section. If the unclear place, can inquire!

 Size of tiny holes on Nano-Tube creates size of bubbles with small diameter. The smaller gas bubbles are, the more efficient their ability of oxygen transfer into the water is (greater surface area). Small air bubbles are suspended in the water longer to increase the number of times that they are brought into the water. Because air bubbles float on the surface more slowly, the rate of oxygen transfer is much higher.
