Hailea Flexible Rubber Air Curtain

comes in 3 sizes; 12", 18', 24" and 36".

Keep your nutrient solution fully oxygenated with an air curtain. Air Curtains great for the bottom of reservoirs and is flexible so that it can be made to fit around bends in the tank.


Porous rubber creates many small bubbles
Mixes and oxygenates your nutrient solution
Oxygenated nutrient solution improves root-health and turbo-charges plant growth
Air pump and air line available separately
Less risk of accidental breakage than with an airstone

How the Hailea 12" (300mm) Flexible Rubber Air Curtain Works:


The flexible air curtain is made of special porous rubber. An inlet nodule is located on the end to allow the air curtain to be connected to an air pump via a length of air line. When connected to an air pump, the air will exit the air curtain through the many pores in the rubber. When the air curtain is submerged in water or a nutrient solution, the effect is that many small bubbles are produced and released from the surface of the special rubber.

The bubbles create movement in the water or nutrient solution keeping it well mixed. The movement at the surface also greatly increases the amount of oxygen being dissolved into it. Dissolved oxygen discourages anaerobic microbes which can cause root diseases and feeds oxygen to the friendly aerobic microbes. An airstone or air curtain helps to keep your plant’s roots healthy while also providing oxygen for the roots to absorb. Adding an airstone or air curtain to your reservoir really does increase the speed of your plant’s growth and creates a healthier root-system. An airstone or air curtain is very highly recommended for all hydroponic systems.

Using the Hailea Flexible Rubber Air Curtain


Connect the air curtain to your air pump using 4mm pvc or rubber air line. If the air line is difficult to fit over the inlet, dipping the end in warm water should make job much easier. Always make sure that your air pump is at a higher level than the surface of the water in your reservoir to prevent water siphoning back into the air pump. Using one of our non-return / check valves (available separately) in the airline to the air curtain will make doubly sure that back-siphoning cannot occur. Lower the air curtain down to the bottom of your reservoir and switch your air pump on. Every so often, gently clean the surface of the air curtain to maintain the air-flow and bubble production. Air curtains do degrade with use and will become clogged over time. Try to make sure you replace them regularly.
