Spiral Mixing Aerator

Spiral Mixing Aerator

Spiral Mixing Aerator (or “rotary mixing aerator”), integrated the structure characteristics of coarse bubble diffuser and advantages of fine bubble diffuser is the latest research and development of new type aerator. The aerator is made up by two parts: ABS distributor and umbrella type dome, employing the form of multilayer spiral cutting to undergo aeration.
