Aqua One Precision SR Series Air Pump for Hydroponics, DWC and Aquariums

💨 Quiet, Reliable Aeration for Hydroponics, DWC and Aquariums

Your reservoir or aquarium is only as healthy as its oxygen levels. The Aqua One Precision SR Series air pump keeps water moving, oxygen flowing and roots or fish thriving around the clock. Built for quiet, continuous operation, these pumps are a go-to choice for hydroponic growers, aquaponic setups and aquarium enthusiasts who need dependable aeration without the noise.

Four models to choose from, so you can match the pump to your system size:

• SR-2500: 160 L/H, single outlet, 2.5W. Perfect for small DWC buckets, single reservoirs or compact aquariums.
• SR-7500: 360 L/H, twin outlet, 3.5W. Great for mid-size systems running two air stones or diffusers simultaneously.
• SR-9500: 400 L/H, twin outlet, 5.2W. Ideal for larger reservoirs or aquariums needing stronger airflow across two zones.
• SR-12000: 1900 L/H, four outlet, 9.4W. Built for large-scale grows, RDWC systems or multi-tank aquarium setups.

🌿 Why Growers and Aquarists Choose the Precision SR Series

In a DWC or RDWC system, your roots are submerged in nutrient solution 24/7. Without a strong, steady supply of dissolved oxygen, root rot sets in fast. These pumps run continuously and quietly, keeping oxygen levels high and water circulating so your roots stay white and your plants keep growing. In aquariums and aquaponic tanks, the same principle applies: good aeration means better filtration, lower ammonia and nitrite buildup, and healthier fish.

🔇 Quiet Enough to Run Day and Night

Nobody wants a buzzing pump keeping them up or disrupting a grow room. The Precision SR Series is engineered for low-noise operation, so you can run it around the clock without it becoming a distraction. The diaphragm design also makes servicing simple: when it's time for a replacement, it's a straightforward job you can do yourself.

🎛️ Speed Control on Every Model

All four models include built-in speed control, so you can dial in exactly the right airflow for your setup rather than running at full blast all the time. This is especially useful in smaller systems where too much turbulence can stress roots or disturb fine bubble diffusers.
