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!
