Danner® Supreme Hydroponics™ Low Volume Air Pump - 4 Watt

Quiet Low-Wattage Reservoir Aeration for Small Hydroponic Systems, 4W

The Danner® Supreme Hydroponics™ Low Volume Air Pump delivers quiet, energy-efficient air to hydroponic nutrient reservoirs at just 4 watts. That dissolved oxygen stimulates root development and supports beneficial microbial activity in DWC buckets, propagation chambers, and small reservoir systems, without the noise or power draw of a larger commercial air pump.

It accepts standard 3/16in air tubing and connects directly to common airstones, air bars, and manifolds without adapters. A 6ft power cord reaches standard outlets from most reservoir positions, and quiet motor construction keeps hum and vibration low during round-the-clock operation.

Key Features & Benefits

• 4-watt energy efficiency — ultra-low power draw for continuous-duty operation through 24-hour grow cycles.
• Quiet motor design — reduced vibration and noise for environments where sound management matters.
• Accepts 3/16in standard air tubing — direct compatibility with standard airstones, air bars, and manifold systems.
• Stimulates root growth — oxygenated nutrient solution accelerates root-zone aerobic activity and nutrient uptake.
• 6ft power cord — reaches standard outlets from most reservoir positions without extension cords.

Who Should Use This

Small-to-medium scale hydroponic growers running DWC buckets, reservoir systems, propagation chambers, and seedling stations are the direct fit for this pump, especially in grow tents or bedroom grows where noise matters.

About Danner

Danner Manufacturing has built pumps and aeration equipment since 1934, growing from a Brooklyn cellar workshop into a family-owned manufacturer now based in Islandia, New York. The Supreme Hydroponics™ Low Volume Air Pump line applies that background to quiet, low-wattage aeration built specifically for small hydroponic reservoirs.

Frequently Asked Questions

Is this pump enough to aerate a 5-gallon DWC bucket?

For a single 5-gallon DWC bucket with a standard airstone, 4 watts generally provides sufficient dissolved oxygen. For larger reservoirs or multiple buckets, step up to a higher-capacity Danner air pump model.

Can I run a water pump in the same reservoir as this air pump?

Yes — air pumps and water pumps serve different functions and can run in the same reservoir at once. Just route the airline tubing so it does not interfere with the water pump inlet.

How is this pump positioned relative to the reservoir?

This pump is an external air pump designed to sit at or above the water level, not inside the reservoir. Only the airline tubing and attached airstone go into the water; a check valve on the tubing adds protection against back-siphoning when power is off.

Is this pump submersible?

No — the Supreme Hydroponics™ Low Volume Air Pump is built for use outside the reservoir. Submerging the pump body itself will damage it.
