The Ring Aerator has a porous, air-permeable hose that is fixed in a stainless steel holder. Its weight keeps the hose stable on the bottom.
The ring shape and the fact that the stainless steel holder makes this hose 'float' above the bottom create not only good aeration but also an enormous water flow.
The hose has virtually no resistance and is therefore ideal for moving bed filters.
Connection 12mm & 18mm.
Min. flow 40 l ltr/min
Max. flow 120 ltr/min
Recommended flow 80 l/min
