stainless steel diffuser stone

Porous Stainless Steel Diffuser Stone OEM Supplier

Actually, Stainless Steel Diffuser Stone commonly referred to named aeration stone or diffuser stone,

they are made by porous stainless steel elements, When you pump air into it with oxygen or carbon dioxide,

thousands of tiny bubbles will appear and diffuse into the liquid.

Main Feature of Porous Stainless Steel Diffuser Stone

The main feature of a porous metal oxygenation stone is its highly controlled and efficient gas diffusion.

This is achieved through two key properties:

1.Porous Structure:

The stone is made of sintered metal, which means tiny metal particles are fused together to create a network of

microscopic pores. These pores allow gas (like oxygen) to pass through while remaining small enough to

generate a large number of very fine bubbles.

2.High Surface Area:

Because of the countless pores, the metal stone has a very high surface area. This increased surface area is

crucial for efficient gas exchange.

The larger the surface area the gas comes in contact with, the more effectively it can dissolve into the liquid.

These two features combine to create a stone that:

*Produces a fine, even stream of bubbles, maximizing oxygen-liquid contact.

*Offers superior gas transfer, promoting efficient oxygenation.

Porous Metal Diffuser Stone vs Plastic Oxygenation Stone

Porous Metal Oxygenation Diffuse Stones:

1.Material:

Typically made from sintered stainless steel

2.Pros:

*Durability:

Very durable, can withstand high temperatures, pressures, and won't crack or break easily. Lasts a long time.

* Efficiency:

Millions of tiny pores create fine, even bubbles for efficient oxygen or CO2 diffusion.

* Cleaning:

Easy to clean and sanitize due to the non-porous metal exterior.

3.Cons:

*Cost: Generally more expensive than plastic stones.

*Weight: Heavier than plastic stones.

Plastic Oxygenation Stones:

1. Material:

Made from various plastics like nylon or ceramic

2. Pros:

*Cost: Affordable and readily available

*Weight: Lightweight

3. Cons:

*Durability: Less durable than metal stones. Prone to breakage and may become brittle over time, especially at high temperatures.

*Clogging: Pores can clog more easily, especially with oils or residue buildup.

*Efficiency: May not produce as fine or even bubbles as metal stones, potentially reducing diffusion efficiency.

In summary:

*If you prioritize durability, efficiency, and ease of cleaning, a porous metal stone is the better choice, despite the higher cost.

*If budget is a major concern, and you don't mind replacing the stone more often, a plastic stone might be sufficient.

Here are some additional factors to consider:

*Application: For purposes like home brewing where sanitation is crucial, metal stones might be preferred.

*Micron Rating: Look for the micron rating of the stone, which refers to the pore size. Lower microns generally create finer bubbles for better diffusion.

Also Here we make a comparison table between Porous Sintered Stainless Steel Diffuser Stone and Plastic Oxygenation Stone:

Feature	Porous Sintered Stainless Steel Diffuser Stone	Plastic Oxygenation Stone
Material	316L Stainless Steel	Plastic (usually PVC or similar materials)
Durability	Highly durable, resistant to corrosion and wear	Less durable, may degrade over time with exposure to chemicals or UV
Temperature Resistance	Can withstand high temperatures	Lower temperature tolerance, can deform or degrade at high temperatures
Pore Size	Precise control, 0.1 - 90μ	Typically larger pores (less control over size)
Pressure Resistance	High pressure resistance, ideal for industrial applications	Lower pressure tolerance, not ideal for high-pressure systems
Oxygenation Efficiency	High oxygen transfer rate due to fine porosity	Generally lower oxygen transfer efficiency
Chemical Resistance	Resistant to a wide range of chemicals and solvents	Limited chemical resistance, may degrade in harsh chemicals
Customization	Fully customizable in terms of size, shape, and pore size	Limited customization options
Cost	Higher initial cost due to material and manufacturing process	Lower initial cost
Applications	Used in industrial applications, brewing, aquariums, etc.	Primarily used in aquariums, less suitable for industrial use
Maintenance	Easy to clean and maintain, long lifespan	Requires more frequent replacement, can be difficult to clean
Environmental Impact	Recyclable and eco-friendly	Less environmentally friendly, harder to recycle
