WATER MASTER Air Pump 2 Outlets (2 x 1.5 L/min)

WATER MASTER Air Pump with 2 Outlets

The WATER MASTER 2-Outlet Air Pump is designed for hydroponic systems requiring continuous aeration in small to medium-sized tanks. Each outlet delivers 1.5 L/min (approximately 90 L/h per outlet), enough to supply two 25–50 mm air stones or a dual manifold with fine-tuning.

The artificial sealing system preserves pressure and ensures a firm flow even during long days, reducing performance drops due to micro-leaks.

The compact chassis minimizes vibrations and facilitates mounting on technical shelves, while the internal design prioritizes thermal stability and low noise levels, ideal for indoor rooms.

In nutrient reservoirs, the addition of microbubbles accelerates gas exchange, increases dissolved oxygen and helps to keep the solution homogeneous, stabilizing EC and pH between irrigations.

The dual outlet allows you to work two zones or two tanks at the same time, or concentrate the flow in a single tank using a "Y" and shut-off valves to balance lines.

As a node within irrigation accessories , this pump contributes to more active roots, less biofilm, and a lower risk of odors associated with anaerobic conditions.

With simple maintenance (cleaning of diffusers and checking of joints), the assembly integrates seamlessly into daily routines, increasing the reliability of the irrigation system and the consistency of each fertigation cycle.

Indoor Growing Water Master Air Pump with 2 Outlets

In indoor growing , constant aeration prevents stratification and dead zones in the tank. The 2 × 1.5 L/min distribution allows for the oxygenation of standard working tanks, ebb and flow tables, or DWC buckets, maintaining a more "live" nutrient solution. The result is noticeable in root development, absorption rate, and overall crop response, especially during periods of high demand.

What is the WATER MASTER 2 Outlet Air Pump used for?

It serves to oxygenate nutrient solution tanks , maintain an active mix during preparation and resting, and feed two independent bubbler lines. It also provides air during transfers, tank cleaning, and fertilizer maturation stages. In recirculation mode, it complements the water pump, ensuring that feeding and watering indoor plants is accompanied by constant oxygenation, key for healthy roots.

For optimal performance, it is recommended to integrate:

• Diffuser stones of 25–50 mm (one per outlet) for fine microbubbles.
• Non-return valves in each line, preventing backflow to the pump.
• Silicone tubing compatible with nozzles for watertight joints.
• Stopcocks and small manifolds to distribute flow and balance pressure.
• Timer if you are interested in alternating ventilation windows with energy saving.

With this set of irrigation accessories , the reservoir maintains uniform oxygenation and stable parameters, improving irrigation consistency within the overall irrigation system .

How do I use the WATER MASTER 2 Outlet Air Pump?

1) Place the unit on a firm surface, slightly above the water level to prevent gravity runoff.
2) Connect silicone tubing to each outlet and add a non-return valve with the arrow pointing towards the diffuser.
3) Install two diffuser stones at the bottom of the tank, separated from each other and with walls for homogeneous coverage.
4) Turn on the pump and check for constant bubbling; adjust with stopcocks until the intensity is balanced in both lines.
5) Clean diffusers periodically and check the tightness of joints to maintain a flow rate of 2 × 1.5 L/min .

A simple maintenance protocol prevents flow loss due to clogged pores or loose connections, and maintains high dissolved oxygen throughout the campaign.
