Yamitsu Air Storm Venturi & Clear Hosetail Pond Koi Aeration Connector

Yamitsu Air Storm Venturi & Clear Hosetail – Pond Aeration Connector

Improve water movement and oxygenation in your garden pond with the Yamitsu Air Storm Venturi & Clear Hosetail, a practical pond aeration solution designed for compatible pumped pond filtration systems.

The Yamitsu Air Storm uses the natural Venturi effect to draw air into flowing pond water, creating a mixture of air and water that helps increase oxygenation without requiring a separate electrical supply for the venturi itself.

Ideal for koi ponds, goldfish ponds and ornamental garden ponds, this innovative aeration device helps support fish wellbeing, biological filtration and healthy pond conditions.

Featuring a transparent body, two interchangeable water nozzles and a demountable coupling, the Air Storm provides a convenient and adaptable solution for pond water returns.

Key Features:

• Yamitsu Air Storm Venturi – Designed to introduce additional air into pumped pond water
• Clear Hosetail Connection – Allows connection to suitable flexible pond hose
• Improves Pond Oxygenation – Draws air into flowing water to support oxygen exchange
• Natural Venturi Action – Operates using pumped water pressure without a separate electrical supply
• No Moving Parts – Simple construction with minimal routine maintenance
• Two Interchangeable Nozzles – Allows adjustment to suit different pump flow rates
• Transparent Housing – Makes it easier to observe water movement and aeration performance
• Demountable Coupling – Allows easier installation, servicing and nozzle changes
• Supports Biological Filtration – Additional aeration helps support oxygen-dependent beneficial bacteria
• Suitable for Koi Ponds – Practical aeration accessory for compatible garden pond systems

How the Yamitsu Air Storm Venturi Works

The Yamitsu Air Storm Venturi operates by using the flow of water from your existing pond pump.

As water passes through the narrowed section of the venturi, its velocity increases and a low-pressure area is created.

This draws atmospheric air into the unit through the air inlet, mixing air with the passing water before returning it to the pond.

The process helps improve pond aeration without requiring a separate motor or moving components within the venturi.

Two Interchangeable Water Nozzles

The Air Storm is supplied with two different water nozzles, allowing the aeration arrangement to be adjusted according to the flow rate of your pond pump.

• Smaller Nozzle: Suitable for lower-output pumped water systems
• Larger Nozzle: Suitable for higher-output pumped water systems

The transparent housing allows you to observe the aeration effect and determine which nozzle provides the most suitable performance for your installation.

Clear Hosetail for Flexible Hose Connections

The clear hosetail provides a practical way to connect the venturi to compatible flexible pond hose.

This makes the assembly useful for pond installations where flexible hose is preferred over rigid solvent weld pipework.

Please check the hosetail dimensions and your existing hose size before installation.

Supports Pond Fish & Biological Filtration

Oxygen is essential for koi, goldfish and other ornamental pond fish.

Adequate dissolved oxygen also supports the beneficial bacteria responsible for biological filtration and the breakdown of harmful ammonia and nitrite.

By introducing air into the returning pond water, the Yamitsu Air Storm can contribute to improved aeration and water circulation.

Installation Guidance:

1. Check that your pond pump and pipework are suitable for the venturi.
2. Select the appropriate water nozzle for your pump output.
3. Connect the venturi to the pumped pond return using the appropriate fitting and clear hosetail.
4. Connect the air inlet tubing and ensure its open end remains above the pond water level.
5. Position the venturi according to the manufacturer's installation instructions.
6. Start the pond pump and observe the air and water mixture.
7. Adjust the nozzle arrangement if required to achieve suitable aeration.

Installation Depth: The venturi is commonly positioned approximately 200–1000mm below water level, depending on available pump pressure and the installation arrangement.

Important Information:

PLEASE NOTE: This listing is for the Yamitsu Air Storm Venturi & Clear Hosetail.

The pond pump, complete filtration system and additional pipework are not included unless specifically stated.

Pumped Systems Only: The venturi requires water to be pumped through it under suitable pressure. It is not designed for gravity-only water flow.

Actual aeration performance depends on pump flow rate, available pressure, installation depth and pipework configuration.

Ensure the air inlet remains above water level and is not obstructed.

Please check the connection dimensions and hose compatibility before purchasing.

The venturi operates using the flow from an existing pump and does not replace the need for adequate pond circulation, filtration or oxygen monitoring.

Improve your pond aeration with the Yamitsu Air Storm Venturi & Clear Hosetail, a practical solution for introducing additional air into compatible koi and garden pond water returns.
