Air pump for oxygenating water and nutrient solutions in reservoirs and small hydroponic systems. The two outlets allow air to be distributed to multiple aeration points, improving solution movement and supporting the root zone.
Key features
- Product type: Air pump for reservoir aeration
- Configuration: 2-outlet version (dual outlet)
- Adjustment: Speed control via dial
- Installation: External use outside the reservoir (not submersible)
- Safety: Grounding and fuse protection required (per documentation)
Overview
What it is for
It is used to introduce air into a reservoir to increase oxygenation and promote better circulation of the solution. Air can be fed into the reservoir using the tube alone or with diffusers, if used.
Who it is for
Recommended for those who manage irrigation reservoirs or nutrient solutions and want to keep the water moving and well oxygenated. Also useful in setups where you want to feed multiple aeration points in parallel.
What makes it different
The presence of two outlets and adjustment via dial make it possible to adapt operation to the needs of the reservoir. The product documentation also reports low-noise operation and multi-speed control.
How to use
Assembly
Connect the air tube (4 mm inner diameter) to the pump outlets. Position the pump above the water level on a flat surface. Install a check valve between the pump and the air tube a few centimetres from the pump to prevent backflow.
Startup
Insert the power plug and set the operating speed using the dial on the back of the unit.
Daily management
Periodically check that the airflow is steady and that the tubes are not blocked or kinked. If used with diffusers, make sure they do not become dirty or encrusted over time.
Maintenance
Clean the air tube and any diffuser regularly to maintain maximum performance. Inspect the power cable regularly for damage or deterioration.
Warnings
Disconnect the power before installation, handling or maintenance. Do not immerse the pump: it is designed to operate outside the reservoir. Do not modify the unit and use only recommended spare parts. Ensure a “drip loop” on the cable to prevent condensation from reaching the socket. The power supply must be grounded and protected with a 3A fuse; if in doubt about wiring, consult a qualified electrician.

FAQ & growing tips
Can the pump be submerged in the reservoir?
No. The documentation indicates that the pump is designed to operate outside the reservoir and must not be submerged.
Which tube should I use for the connection?
The guide indicates an air tube with an internal diameter of 4 mm.
Is a check valve necessary?
Yes. The guide recommends always using a check valve on the outlets to prevent water from being drawn back toward the pump.
How can I adjust operation?
There is a dial on the back of the unit that allows you to choose the operating speed.
Is there a warranty?
The documentation states a 12-month warranty from the date of purchase, covering actual failures or mechanical defects, with exclusions for normal wear, accidental damage, modifications or improper use.
