1 . Compact structure , small area occupied , easy to install ;
2 . Except for the air inlet , all the parts are in water and noise
level is very low ,
3 . More air intake , more and small bubble produced and high
oxygen dissolution ;
4 . Not necessary to provide air source , no air blower and
engineering cost is fairly low .
5 . ABS submersible technology imported from Germany is adopted .
The flow channel of the impeller is adopted of blockless and the
operation is safer and more reliable .
