Cylindrical Ceramic Air Stone for Aquarium Aeration

Product Description

Product Description

Ceramic Aeration Stone

Our microporous ceramic aeration plate is sintered from high-purity alumina ceramic under high temperature. It features uniform interconnected micropores, which can split compressed air into fine microbubbles. This greatly expands the gas-liquid contact area and improves dissolved oxygen efficiency for water treatment and aquaculture systems.

Air Stone

This cylindrical porous ceramic air stone is manufactured by high-temperature sintering technology. The uniform microporous structure can break airflow into plenty of fine and smooth bubbles. It greatly expands the contact area between air and water, improving oxygen dissolution efficiency and realizing stable and continuous water aeration.

Made of sintered ceramic, this aeration column has outstanding corrosion resistance and aging resistance for long-time underwater use. It comes with a square fixing base and barbed hose connector for simple, firm installation. We can adjust product dimensions, pore size and air flow according to your working requirements, supporting OEM and ODM customization.

Ceramic Cylinder Air Stone

It is widely applied in many aeration projects, including aquarium fish tanks, aquaculture ponds, sewage wastewater treatment and biochemical water treatment tanks. It works well for oxygen supply, gas mixing and gas-liquid mass transfer, serving as a reliable gas diffusion component for industrial and aquaculture water treatment.

Advantages:
1. Saves liquid oxygen and increases oxygen utilization rate
2. Uniform atomization, low noise
3. Safe and durable, excellent performance
4. Resistant to acids and alkalis, long service life
