Tube Filter (Duplex In-Line Filtration Strainer)

This tube filter is a compact, high-efficiency filtration solution designed to remove small solid particles from pipeline liquids, protecting compressors, pumps, instruments, and other equipment. Its advanced design ensures optimal performance and reliability across various industrial applications.
The filter undergoes a multi-stage polishing process, achieving a contact surface roughness of Ra 0.4 µm, meeting near-sanitary grade standards. Its fully mirror-polished finish enhances both cleanliness and operational efficiency.

Applications

Ideal for filtering particles from various liquids, including edible oils, beverages, alcoholic drinks, and food-grade liquids. Also suitable for filtering chemicals and protecting downstream equipment in chemical processing plants.

Operating Conditions

Max. operating temperature: 150℃

Materials

Filter body: Stainless steel (304, 316L)
Exhaust/liquid valves: Stainless steel (304, 316L)
Seals and gaskets: Made from EPDM, PTFE, fluororubber, and silicone

Connection

Installing filter housing: Uses quick connect fittings
Inlet/outlet: 2’’/2.5’’/3’’ tri-clamp fittings

Surface Finish

Finish type: Mechanical polishing, electrolytic polishing, sandblasting
Polishing precision: Inner wall 0.4 µm, outer wall 0.6 µm
