Porous stainless steel filters for bubble stones are made by compressing stainless steel powders under high pressure and sintering them together at high temperatures to create a porous structure. The resulting filters are highly durable, corrosion-resistant, and can withstand harsh operating conditions.

Parameters

Material: stainless steel powder

Pore size: 0.2-100 microns

Porosity: 30%-45%

Thickness: 0.5-10mm

Diameter: 5-300mm

Features

High durability: Porous stainless steel filters are highly resistant to corrosion and can withstand harsh operating conditions, making them ideal for use in a variety of industries, including chemical, petrochemical, and pharmaceutical.

Uniform bubble size: The porous structure of these filters allows for the production of uniform and consistent bubbles, which is critical for efficient gas exchange and aeration.

High gas permeability: The high porosity and small pore size of these filters enable efficient gas permeation, allowing for the rapid dissolution of gases into liquid media.

Easy to clean: Porous stainless steel filters can be easily cleaned using a variety of techniques, including backwashing, ultrasonic cleaning, and chemical cleaning.

Applications

Aquariums and fish tanks: Porous stainless steel filters are commonly used in aquariums and fish tanks as aeration devices. They produce uniform and consistent bubbles that promote the growth of aquatic organisms and improve water circulation.

Chemical industry: Porous stainless steel filters are used in the chemical industry for gas-liquid separation and purification, as well as in catalysis and reaction processes.

Pharmaceutical industry: Porous stainless steel filters are used in the pharmaceutical industry for gas-liquid separation, filtration, and purification of drugs and biological products.

Food and beverage industry: Porous stainless steel filters are used in the food and beverage industry for gas-liquid separation, filtration, and purification of beverages, such as beer and wine.

Oil and gas industry: Porous stainless steel filters are used in the oil and gas industry for gas-liquid separation and filtration of natural gas and crude oil.

The metal microporous filter cartridge processed by stainless steel irregular powder can be isostatically pressed, molded and extruded. It has good permeation filtration performance and high filtration accuracy, as well as certain strength and toughness, and can be used at a high temperature of 600 C.
The metal microporous filter cartridge is mainly used in basic industries such as petroleum, chemical industry, and environmental protection as filter materials, porous electrode materials, sound-absorbing materials, shock-absorbing materials, divergent cooling materials, catalysts and catalytic reduction materials, antifreeze and buffer materials.
