Charles Austen 7 Inch Air Ring Bubbler

High performance porous micro bubble diffuser designed to deliver a dense stream of ultra fine bubbles for superior aeration. This aeration ring increases dissolved oxygen levels and keeps water or nutrient solutions fully mixed and oxygen rich, supporting healthier root systems and stable growing conditions.

The diffuser is made from a durable rubber and polymer housing packed with micropores that release consistent, fine bubbles. This creates a high surface area for oxygen transfer, making it ideal for hydroponic tanks, reservoirs, aquariums and any system that relies on clean, oxygenated water.

Key Features

• Ring shaped porous diffuser for full 360 degree aeration.
• 180 mm size for even bubble coverage across medium reservoirs.
• Generates very fine bubbles for efficient oxygen transfer.
• Durable rubber and polymer construction designed for long service life.
• 8 mm inlet fitting, compatible with standard air pumps and tubing.
• Includes rubber suction feet for secure placement at the tank bottom.
• Low maintenance device with reliable long term performance.

How It Works

When connected to an air pump, air is pushed through thousands of tiny pores in the diffuser. As the bubbles rise, they circulate the water and break the surface tension, increasing gas exchange and helping more oxygen dissolve into the solution.

The result is a well oxygenated environment that supports stronger plant roots, encourages beneficial aerobic microbes and helps prevent anaerobic conditions that can lead to root problems.

How to Use

• Soak the diffuser in water before the first use to activate the pores.
• Connect the 8 mm inlet to your air pump using compatible airline tubing.
• Place the diffuser flat at the bottom of the tank for full bubble distribution.
• Secure it with the included suction feet to prevent movement.
• Use moderate airflow to maintain an even bubble pattern.
• Rinse occasionally to remove mineral buildup and keep pores clear.

Applications

• Hydroponic reservoirs and aerated tanks.
• DWC and RDWC systems.
• Aquariums and aquatic systems requiring reliable oxygenation.
• Mixing tanks for nutrient preparation.

This micro bubble aeration ring is simple to install, easy to maintain and highly effective at boosting dissolved oxygen levels for healthier, faster growing plants and cleaner water management.
