Sterile Filter for air and gas filtration

What are Sterile Filters?

Sterile filters are essential components in industrial and medical applications where air and gas quality is crucial. They are designed to remove contaminants, bacteria, and other undesirable particles from air and gases, ensuring that the processes dependent on this air operate safely and effectively.

Our Sterile Air Housings


Our sterile air housings are the standard solution for industrial air filters and process sterile filters. We offer a comprehensive series consisting of 12 single housings (with one sterile filter element) and 6 multi-housings (with 3 to 10 filter elements).

Made from stainless steel 1.4301 (V2A) and 1.4404 (V4A), our housings meet the highest industry standards. All products are designed, tested, and manufactured according to the AD 2000 guidelines and are approved according to the PED 97/23/EC for fluids in fluid group 2.

Benefits of Van Borselen Filters' Sterile Filters

  • High quality: Made from strong and durable materials designed to provide long-lasting performance.
  • Customer-oriented design: Our housings are designed with the user in mind, making installation and maintenance straightforward.
  • Safety and reliability: Complies with strict safety standards, ensuring safe operation in your processes.

Applications

Sterile filters are commonly applied in sectors such as the pharmaceutical industry, food processing, biotechnology, and more. Whether you are a small business or a large enterprise, our sterile air housings provide a reliable solution for all your filtration needs.

A sterile air filter removes bacteria, microorganisms, and particles from air, steam, or gas streams. It ensures that only clean, sterile air or gas reaches sensitive products or processes — essential in the food & beverage, pharmaceutical, and biotechnology industries.

Sterile air filters are commonly used for:

  • Tank venting and de-venting

  • Compressed air filtration in production environments

  • Sterile gas filtration in bioreactors and fermentation processes

  • Vacuum breaks on autoclaves

  • Steam and sterile gas systems

Our product range includes:

  • PTFE membrane filters for sterile air and gas applications

  • Tank vent filters (P-BE) ensuring 100% sterility during storage

  • Sterile air filter cartridges (P-SRF) with 99.99998% efficiency

  • Capsule filters (PTFE, PVDF, PP) for compact systems and instruments

  • Stainless steel filter housings for compressed air and sterile gas lines

  • PTFE filters are hydrophobic, ideal for sterile air and gas filtration, and resistant to high temperatures.

  • PVDF filters are hydrophilic, chemically resistant, and suitable for liquid and venting applications.

All housings are made from stainless steel (1.4301 or 1.4404) and meet the highest industry standards (AD 2000, PED 97/23/EG). This ensures durability, pressure resistance, and safety even in demanding operating conditions.

A vent filter with a 0.2 µm sterile membrane prevents microorganisms or particles from entering the tank during filling or emptying. This ensures that the product inside remains sterile at all times.

Yes. Most PTFE and P-SRF filters can withstand repeated SIP (Steam-In-Place) cycles without loss of performance, making them ideal for pharmaceutical and biotechnological applications.

Filter lifetime depends on the process conditions, but due to the durable membrane and stainless steel housing, these filters can withstand multiple sterilization cycles. Regular integrity testing is recommended for optimal safety.

With over 100 years of filtration expertise, Van Borselen Filters provides reliable and long-lasting solutions for sterile air, gas, and steam filtration.
Our filters combine high efficiency, robust stainless steel design, and easy system integration, supported by expert technical advice and fast delivery from stock.
