Description

Unlike the standard silica air stones, these can be cleaned time and time again without wearing down. These air stones are made of aluminum oxide, the same material used for grinding stones which makes them extremely durable. With increased durability, there has been nothing sacrificed in the quality of aeration delivered to your pond, tank or lagoon. 

These airstones break the air flow into small air bubbles to increase the surface area and optimize transfer rate of oxygen into the water. Small air bubbles also enable the bubble column to move water with it and so create and upward flow and efficient circulation of your water body.

If you're aerating an earth pond, you might consider our 7" round air stones specifically made for earth-bottom ponds.

Maximum air volume per air stone is: 1.5" - 0.25 cfm; 2" - 0.20 cfm; 3" - 0.35 cfm; 6" - 0.50 cfm; 9" - 0.75 cfm; 12" - 1.00 cfm. 

Width on all air stones is 1-1/2" x 1-1/2", except the 2", which is 2" x 1" x 1".

These airstones are available with different fittings, so be sure to choose the appropriate size for your existing tubing or application. Not sure of the size you need? Call us and we can help.
