Metal Filter—Reliability When Plastic Is Not an Option
In the harshest corners of industry—where temperatures melt polymers and pressures crush standard cores—LOONG FILTRATION stands firm. Our Metal Filter Cartridges are the heavy artillery of filtration, designed for processes where failure is simply not acceptable.
We specialize in Sintered Porous Metal Media. Unlike simple wire mesh screens, our technology involves high-temperature vacuum sintering, which fuses metal particles or wires at their contact points. The result? A rigid, permanent filtration matrix that maintains its pore structure even under massive stress.
Select Your Metal Filtration Technology
We categorize our metal filters by their structural mechanics to help you solve specific fluid challenges.
1. Sintered Stainless Steel Mesh (The Pleated Powerhouse)
Construction: Multiple layers of woven wire mesh (SS304 / SS316L) are vacuum-sintered together.
Why Choose It:
High Permeability: Excellent flow rates with low pressure drop.
Pleatable: Can be pleated to increase surface area by 5-10x compared to cylindrical tubes.
Cleanable: Easy to backwash or chemically clean.
Ideal For: Hydraulic oils, superheated steam, and polymer melt filtration.
2. Sintered Metal Powder (The Depth Specialist)
Construction: Metal powder (SS316L or Titanium) is pressed into molds and sintered. This creates a tortuous path for depth filtration.
Why Choose It:
Ideal For: Catalyst recovery, fine chemical processing, and ozone diffusion.
3. Titanium Rod Filters
Construction: Pure Titanium powder sintering.
Why Choose It: Unmatched corrosion resistance in highly oxidizing environments or chlorine-based processes where Stainless Steel would pit or crack.
Ideal For: Decarbonization in pharmaceuticals and corrosive chemical intermediates.
Metal Filter:Engineered for Reuse (The ROI Factor)
A LOONG metal filter is an investment, not a disposable cost.
Designed for longevity, our cartridges can be regenerated multiple times using:
Ultrasonic Cleaning: For fine particulate removal.
High-Temp Burnout: To remove organic residues/polymers.
Acid/Alkali Bath: To dissolve chemical fouling.
Backflushing: For online automated cleaning systems.
