Large Cylinder Airstone

Divide your total blower air flow by the 20 LPM each stone passes — a 200 LPM blower, for example, will run about 10 stones.

It has an 8 mm barb, so standard 8 mm airline pushes straight on.

No — it is a low-pressure design intended for economical regenerative blowers rather than high-pressure air.

A medium pore structure giving consistent medium bubbles suited to general aeration duties.

Ponds, aquaria, holding tanks and other aquatic environments where a large air volume is needed from one diffuser.

A low-pressure cylinder airstone for general aeration of tanks, ponds and aquariums running on a regenerative blower.
