Air Injection Ring

Our exclusive ALIEN® Air Injection Rings produce bubbles over a a wider area than most air stones and feature pinhole-sized pores to create the tiniest bubbles possible. The smaller bubbles maximize the surface area of oxygen in contact with the nutrient solution for maximum oxygenation, resulting in highly-aerated, healthy root zones for your deep water culture plants.

Air Injection Rings are made from a flexible rubber, so are less prone to clogging than normal air stones as increased air pressure temporarily widens the pores to expel any foreign debris.

Air Injection Rings are 9" / 23cm in diameter with a 6mm / 3/8" barbed connector for the air line. They can be held to the bottom of your pot with 3 of our RDWC Suction Cups per Air Injection Ring (sold separately).

Each Air Injection Ring needs 2.6 gallons of air per minute (10 liters of air per minute) to function properly.
