Overview

The stainless steel duplex filter is the core filtering element of the duplex switching filter, which plays a key role in intercepting fluid impurities and ensuring the safe operation of downstream equipment. It is widely suitable for stainless steel quick installation duplex filters in industries such as chemical, food and beverage, pharmaceutical, and water treatment.

Product Details

Stainless steel double filter screenBasic core parameters

filtration accuracy	1~2000μm	Accuracy selection needs to match fluid impurity particle size: 1-10 μ m, suitable for pharmaceutical drugs and electronic grade pure water; 10-100 μ m is suitable for food and beverages (such as juice and edible oil); 100-2000 μ m suitable for coarse filtration of chemical raw materials and industrial cooling water
Filter structure	Single layer mesh/multi-layer composite mesh/sintered mesh	Single layer mesh: Low cost, suitable for coarse filtration; Multi layer composite mesh: composed of different mesh filters stacked together, with high filtration accuracy and good strength; Sintered mesh: Made by high-temperature sintering of stainless steel fibers, with uniform pores, pressure and corrosion resistance, and can be repeatedly cleaned
Tolerance performance	Working temperature, working pressure	Conventional stainless steel filters can withstand temperatures ranging from -20 ℃ to 200 ℃ and withstand pressures of 0.6~1.6MPa; Special materials (such as Hastelloy) can withstand higher temperatures and stronger corrosive media
size adaptability	Outer diameter, inner diameter, thickness	Accurate matching with the filter basket/cartridge of the dual filter is required, with common quick installation caliber specifications ranging from DN25 to DN200, and support for non-standard customization

Stainless steel double filter screenMainstream materials and applicable scenarios

The material of the filter directly determines its corrosion resistance and service life, and the selection should be based on the characteristics of the fluid medium:

304 stainless steel

Features: High cost-effectiveness, resistance to weak acids and bases, good mechanical strength
Applicable scenarios: drinking water treatment, food and beverage (beer, mineral water), ordinary chemical fluid filtration

316L stainless steel

Features: Contains molybdenum element, has stronger corrosion resistance, can withstand seawater, organic acids, and weakly oxidizing media
Applicable scenarios: Pharmaceutical industry (liquid filtration), seawater desalination, fine chemicals, dairy processing

Sintered stainless steel mesh

Features: Stable porosity, controllable filtration accuracy, impact resistance, easy cleaning, and high-temperature sterilization capability
Applicable scenarios: Biopharmaceuticals (vaccines, serum filtration), sterile preparations, high-purity gas filtration

Special materials

Hastelloy: resistant to strong corrosion (such as hydrochloric acid and sulfuric acid), suitable for chemical strong acid and alkali environments;
Titanium alloy: resistant to seawater corrosion, suitable for marine engineering and seawater filtration.
