Brief Introduction

Stainless Steel Sintered Filter Element is a high-performance filtration component manufactured through powder metallurgy technology, where stainless steel powder (typically 304, 316, or 316L) is sintered at high temperatures to form a porous, three-dimensional network structure. This unique manufacturing process creates a filtration medium with controlled pore size distribution, high mechanical strength, and excellent permeability.

The filter element features a self-supporting structure with interconnected pores, available in various configurations including cylindrical pleated, tubular, disc, and conical shapes. Filtration precision typically ranges from 0.5 to 100 microns, with porosity reaching 30-50%.

Features

1. Exceptional Thermal and Chemical Stability

Withstands temperatures from -200°C to 650°C without performance degradation

Excellent corrosion resistance to acids, alkalis, and organic solvents (except hydrofluoric acid and strong chlorides)

Maintains structural integrity under thermal cycling and shock conditions

2. Superior Mechanical Strength and Durability

High compressive strength (typically 1-5 MPa) prevents collapse under pressure differentials

Withstands backpressure pulses up to 15 bar during cleaning cycles

Resists vibration and mechanical impact in demanding industrial environments

3. Optimized Filtration Performance

Uniform pore distribution ensures consistent filtration efficiency

High dirt holding capacity with minimal pressure drop increase

Regenerable through backflushing, ultrasonic cleaning, or thermal treatment

4. Sanitary and Compliance Features

Smooth surface finish (Ra ≤ 0.8μm) prevents bacterial colonization

Meets FDA, cGMP, and USP Class VI requirements for pharmaceutical applications

No media migration or fiber shedding during operation

5. Economic and Environmental Benefits

Service life 3-5 times longer than conventional filter elements

100% recyclable material with minimal environmental impact

Reduced waste generation and disposal costs
