A porous sintered stainless steel filter for air-liquid separation is a specialized filtration component designed to separate gaseous and liquid phases in industrial processes. Manufactured via high-temperature sintering of stainless steel powder, it features a uniform, interconnected porous structure that enables efficient capture of liquid droplets or mist from gas streams (or vice versa) while maintaining low flow resistance. Its durability, corrosion resistance, and reusability make it ideal for demanding air-liquid separation scenarios across industries.
| Performance Indicator | Typical Range | Significance for Separation |
|---|---|---|
| Pore Size | 1–50μm | – 1–5μm: For fine mist separation (e.g., removing submicron oil mist from compressed air).
– 10–50μm: For coarse droplet removal (e.g., dehumidifying industrial exhaust gas). |
| Porosity | 35%–55% | Balances two needs: High porosity (≥40%) minimizes gas flow resistance (avoids pressure drop); moderate porosity (≤55%) ensures sufficient surface area for coalescence. |
| Liquid Removal Efficiency | ≥99.5% (for droplets ≥0.5μm) | Measures how well the filter captures liquid—critical for applications like compressed air drying (to prevent equipment corrosion) or natural gas processing (to remove water/hydrocarbon mist). |
| Pressure Drop | ≤0.1MPa (at flow rate 10–50 m³/h) | Low pressure drop reduces energy consumption (e.g., in air compressors) and avoids process disruption. |
| Operating Pressure | 0.1–3MPa | Withstands high gas/liquid pressures in industrial systems (e.g., petrochemical pipelines, hydraulic systems). |
| Operating Temperature | -20°C–350°C | Suitable for high-temperature streams (e.g., steam mist separation) or low-temperature applications (e.g., cryogenic gas drying). |
Advantages Over Traditional Separation Media
Typical Industrial Applications
This filter is widely used in scenarios where reliable air-liquid separation is critical to process safety, equipment longevity, or product quality:
Compressed Air & Gas Processing
Compressed Air Drying: Removes water mist and oil mist from compressed air to protect pneumatic tools, valves, and paint-spraying systems (prevents corrosion and finish defects).
Natural Gas Treatment: Separates water droplets and hydrocarbon condensates from natural gas pipelines to avoid pipeline corrosion and ensure efficient combustion.
Industrial Exhaust Purification: Captures liquid mist (e.g., sulfuric acid mist in battery manufacturing, solvent mist in coating plants) from exhaust gas before emission.
Hydraulic & Lubrication Systems
Hydraulic Oil Degassing: Removes entrained air bubbles from hydraulic oil to prevent cavitation (which damages pumps and cylinders) and improve system responsiveness.
Lubricating Oil Filtration: Separates oil mist from gearbox or engine exhaust gases to reduce oil loss and maintain lubrication efficiency.
Chemical & Petrochemical Industry
Reactor Off-Gas Treatment: Separates liquid droplets (e.g., solvent droplets in polymerization reactors) from off-gases to recover valuable solvents and comply with emission standards.
Acid Gas Scrubbing: After scrubbing acidic gases (e.g., HCl, SO₂) with liquid absorbents, the filter removes entrained absorbent mist from the cleaned gas.
Food & Pharmaceutical Industry
Steam Sterilization: Removes water droplets from saturated steam used to sterilize equipment (ensures uniform heating and prevents wet sterilization failures).
Beverage Processing: Separates CO₂ gas bubbles from liquid beverages (e.g., soda, beer) during filling to avoid overflow and ensure consistent carbonation levels.

Production
1. Substrate treatment: it needs to be treated by roughing, cleaning and removing oil, which can increase the compactness of catalytic.
2. Brushing coating:After substrate treatment, it will be proceeded brush coated. The main coated content is platinum group metal, which is a kind of mixed solution.Then, heat treatment will be going on after drying.The whole procedure need to be repeated many times. This method is better to form thin oxide catalytic that is lamellar adhere to substrate surface.
