Specifications
Porosity and filtration accuracy
Pore size range: Commonly available at 1–250µm (0.2–200µm can also be customized).
Porosity: about 30–45% (some manufacturers can reach 60%), which can be controlled in the 35–50% range.
Filtration efficiency: Particle interception rate can reach 99.98% when the pore size is 5 µm.
Pressure and temperature specifications
Maximum working pressure: 0.3–5MPa (approximately 3–50bar), some cylinder products can withstand 30MPa.
Operating temperature range: oxidation environment -250°C ~ 200°C; reduction environment can reach 450°C.
Mechanical properties
Density: 4.5–6.5g/cm³
Tensile strength: approximately 9.8–83.4MPa
Massiveness: Welding elongation is about 2–3%
Linear expansion coefficient: ≈17–18 ×10⁻⁶ /°C
Common sizes and termination methods
Disc/sheet: diameter φ4–300mm, thickness 1–70mm.
Cylindrical/filter element: diameter 4–300mm, length 40–900mm.
Termination type: The muffler is often in a cylinder structure; the filter element can be threaded, open or flange end.
Cleanliness and reusability
Cleanable and regeneration: supports high-pressure water/gas backwash, chemical cleaning and ultrasonic cleaning, and the performance recovery rate is above 90%.
Strong durability: The structure is stable after multiple cleanings, without pollution degradation.
Application scenarios
Liquid and gas filtration: suitable for oil, water, chemical filtration, and widely used in petrochemical, pharmaceutical, food and other fields.
Silence, steady flow, and spray blocking: dryer, exhaust valve, breathable hole, etc. are used as muffler or pressure stabilizer hole.
Compressed air purification: Filter elements are used to remove water mist, oil mist and solid particles.
Precision applications: such as fuel, instrumentation, automation equipment for microfiltration or splash protection.
Select suggestions
Select the pore size according to the filter particle size (such as 1/5/10/25/50/100µm standard);
Select materials according to the working conditions (maximum pressure and ambient temperature meet the requirements);
Size and shape matching equipment (confirm the diameter, length, port style);
Evaluate cleaningability (recoil, chemical cleaning adaptability).
