Operating cost, be not necessarily to extra power under conditions of, while realize into water, aeration, transformation water inlet direction, transformation aeration side
To equal multi-functionals.
4) it is not necessarily to blower, gas caused by blower is avoided to have the phenomenon that ethereal oil pollutes breeding water body.
5) it is uneven to overcome traditional aeration plate Air Bubble Size, the problem that dissolved efficiency is low, the pressure loss is big,
6) water outlet can auto-changing direction, have preferably plug-flow effect to fishpond, promote the efficient discharge of particulate dirt.
7) comprehensive aeration can be directly carried out to breeding water body, the carbon dioxide for promoting fish breathing to generate overflows
Water body.
8) applied widely, it can carry out applicable, be also applicable in water treatment system in flowing water pond and recirculated water pond.
9) ingenious in design, structure optimization, operational effect is good.
