Stainless Steel Sterilizing Filter for Compressed Air Systems 1.0MPa

The Stainless Steel Sterilizing Filter is a high-performance terminal filtration solution designed for industries requiring absolute air sterility and contamination control. Manufactured with SUS304/316 stainless steel and equipped with advanced PTFE membrane filtration technology, it delivers reliable sterile air for critical production environments in pharmaceuticals, semiconductors, food processing, and fine chemical applications.

Product Overview

This sterilizing filter is engineered to operate under a working pressure of 1.0MPa, providing a robust and stable filtration system for compressed air sterilization processes. Both the internal and external surfaces are precision-polished to Ra0.3, ensuring a smooth, residue-free structure that meets stringent hygienic requirements.

The filter element utilizes high-efficiency hydrophobic PTFE folded membrane technology, designed for sterile-grade air filtration. It has passed 100% DOP integrity testing, ensuring consistent and validated performance in critical applications.

Absolute Sterilization Performance

Filtration accuracy reaches 0.01μm, with a logarithmic reduction value ≥6 (99.9999% efficiency). This ensures near-total removal of bacteria, microorganisms, and bacteriophages from compressed air systems.

Efficiency rating is ≥99.999%, providing absolute sterility assurance for sensitive production environments where air purity directly impacts product safety and quality.

Certification and Compliance Standards

The stainless steel housing and filter materials have been tested by SGS, an internationally recognized third-party certification organization, confirming compliance with food-grade and pharmaceutical-grade safety requirements.

The product meets multiple global regulatory standards, including:

FDA 21 CFR 177.2600
USP Class VI
cGMP
GMP
ISO 14644 cleanroom standards

These certifications ensure full compliance with international pharmaceutical and clean manufacturing regulations.

Advanced Filter Structure and Integrity

The filter element is constructed using high-strength hydrophobic PTFE (polytetrafluoroethylene) membrane with reinforced multilayer support, ensuring durability and resistance to rupture.

It supports repeated online steam sterilization (SIP), making it suitable for continuous sterile production systems.

Each unit is supplied with complete bubble point test data and filter integrity validation services, ensuring full traceability and operational reliability.
