The stainless steel filter disc is an industrial filtration component manufactured from high-quality 316L stainless steel powder through a sintering process. This product, with a diameter of 25 mm, a thickness of 1 mm, and a precise 40-micron filtration rating, represents a standard-thickness, conventional model.

The 1 mm standard thickness provides optimal mechanical strength while maintaining excellent fluid permeability. The 40-micron filtration rating is a practically proven balance, effectively capturing harmful particulate contaminants without imposing excessive flow resistance, making it suitable for a wide range of general filtration scenarios.

Products Features

1. A Precisely Uniform Filtration Barrier

Specialized manufacturing creates a three-dimensional mesh filtration layer with exceptionally uniform pore distribution and structural stability. This consistency prevents issues like localized premature breakthrough or uneven clogging, extending the disc's service life under demanding conditions and ensuring reliable, repeatable filtration quality.

2. Superior Mechanical and Structural Integrity

This disc offers exceptional resistance to pressure and deformation, surpassing standard filter screens. It withstands common process pressure fluctuations and fluid surges, maintaining pore stability to prevent deformation or material failure caused by high differential pressure.

3. Exceptional Environmental Resistance and Durability

The stainless steel construction provides inherent resistance to a wide range of corrosive chemical media and stable performance across high and low temperatures. Whether in continuous operation or intermittent use, it delivers consistent performance, minimizing frequent replacements due to material degradation and offering long-term lifecycle value.

4. Economic Advantage from Easy Maintenance and Reusability

Unlike disposable filter cartridges, this sintered stainless steel disc is inherently cleanable and reusable. When surface contamination reaches a specified level, effective cleaning via methods like backflushing or ultrasonic cleaning can restore most of its original filtration capacity, reducing long-term operational costs.

applications

1. Internal Circuit Protection for Small Precision Instruments

In laboratory analyzers, medical devices, or high-value compact process equipment, internal fluids such as hydraulic oil, coolant, or process media require continuous purification. This compact disc integrates seamlessly into key points of circulation lines, intercepting wear-generated metal debris, assembly residues, or gel-like byproducts to protect sensitive components and ensure instrumental accuracy and reliability.

2. Final Defense Line for Industrial Pneumatic Systems

Oil mist, condensed moisture, and pipeline scale in compressed air pose significant risks to pneumatic tools, cylinders, and precision valves. Installed at branch line ends or before component inlets, this disc acts as a robust final barrier, ensuring clean, dry air reaches actuators. This prevents internal corrosion, seizing, and contamination of end products.

3. In-Line Purification for Chemical Reagents and Plating Solutions

In chemical dosing or electroplating lines, fluid purity directly impacts reaction outcomes and coating quality. This corrosion-resistant disc, placed after transfer pumps or in tank circulation loops, continuously removes impurities from raw materials, reaction precipitates, or equipment-shed particles, maintaining the chemical and physical cleanliness critical for uniform, bright finishes.

4. Particulate Control in Fuel and Lubrication Systems

For internal combustion engines, generators, fuel boilers, and centralized lubrication systems, fluid cleanliness is paramount for equipment longevity. This disc can be used in compact filter assemblies to effectively remove solid contaminants from fuel and wear metals from lubricating oil, reducing risks like injector clogging, abnormal wear, and bearing damage.

5. Pre-Filtration for Process Water and Recycling Systems

In applications like paint pre-treatment rinse water recycling, cooling tower water treatment, or industrial wastewater reuse pre-treatment, removing suspended solids is essential. This disc serves as an effective pre-filter in multi-stage systems, intercepting larger particles like silt, rust, and fibers to protect and extend the service life of downstream fine filtration units.

6. Safety Filtration in Food and Beverage Production

For final safety filtration of non-high-viscosity liquids (e.g., syrups, flavorings, bases, process water) in filling lines, ingredient systems, or small-scale brewing, food-grade stainless steel construction is essential. This disc safely contacts food-grade fluids, effectively removing potential micro-solids, crystals, or fermentation residues to ensure product clarity, taste, and compliance with food safety standards.
