Sterile Venting Solutions with Aegivast™ ACE Hydrophobic PTFE Vent Filters from CoPure

Across Australia’s biopharmaceutical, fermentation, food, and life‑science industries, vent filters play a critical yet often underestimated role in maintaining sterility, process integrity, and regulatory compliance. Whether venting bioreactors, fermentation tanks, storage vessels, or single‑use systems, the right vent filtration solution is essential to protect products from airborne contamination while allowing controlled gas exchange.

Venting Filters from CoPure, including the Aegivast™ ACE Hydrophobic PTFE Vent Filter series, deliver sterilising‑grade performance designed for demanding Australian process environments.

Why Vent Filters Are Essential in Modern Processing

Vent filters are primarily used in air and gas filtration applications where containers, tanks, or systems must “breathe” without introducing contaminants. Typical applications include:

• Bioreactors and fermentation vessels
• Media and buffer storage tanks
• Carboys and laboratory containers
• Single‑use bioprocess systems

In these systems, incoming or outgoing air can carry microorganisms, fine particles, and moisture. Without effective filtration, this can lead to:

• Microbial contamination
• Product spoilage or batch rejection
• Regulatory non‑compliance
• Reduced process reliability

For Australian manufacturers operating under GMP and USP frameworks, vent filters must provide high airflow with proven microbial retention—without creating excessive pressure drop.

Key Selection Criteria for Vent Filters in Australia

When selecting vent filters in Australia, two technical factors dominate performance:

1. Airflow capacity – The filter membrane must offer sufficient surface area to handle the required gas exchange without restricting pressure.
2. Microorganism and particulate retention – Sterilising‑grade performance is essential in pharmaceutical and fermentation applications.

Cobetter’s vent filter portfolio addresses both requirements, offering effective filtration areas ranging from 7.3 to 20 cm², enabling precise matching of filter size to system airflow demands.

Aegivast™ ACE Vent Filters: Advanced Hydrophobic PTFE Technology

The Aegivast™ ACE Vent Filter series is a sterilising‑grade gas filtration solution specifically developed for biopharmaceutical and high‑purity applications. These filters are available in disc and syringe configurations and are well-suited for small containers, bioreactors, and tubing systems.

Membrane and Housing Design

• Membrane: 0.2 μm hydrophobic PTFE
• Support layer: Polyester
• Housing: High‑purity polypropylene (PP)

The natural hydrophobicity of PTFE prevents liquid penetration while allowing efficient gas flow, ensuring reliable venting even in humid or condensate‑prone environments.

Technical Specifications Overview

Filtration Area Options

This range allows Australian users to scale venting capacity based on vessel size and gas flow requirements.

Operating Limits

• Pore size: 0.2 μm
• Max operating temperature: 50°C
• Max differential pressure @ 25°C:
  • 0.24 MPa (V37, V42, V50A)
  • 0.42 MPa (V50D)

Sterilisation Capability

• Autoclavable for 30 minutes at 130°C (up to 20 cycles)
• Compatible with gamma irradiation
• Not suitable for inline steam sterilisation

Filters are supplied non‑sterile and individually double‑bagged (10 pcs per pack), supporting controlled cleanroom handling.

Proven Sterilising‑Grade Performance

Aegivast™ ACE vent filters are fully validated in accordance with ASTM F‑838 guidelines, demonstrating reliable retention of airborne microorganisms.

Microbial Retention Validation

• Retains ≥1 × 10⁷ CFU/cm² Brevundimonas diminuta (ATCC™ 19146)
• Low pressure drop ensures stable airflow during operation

Endotoxin and Biocompatibility

• Endotoxin limit: < 0.25 EU/mL (WFI system), USP <85>
• Meets USP <88> Class VI Biological Reactivity Test

These characteristics make the filters suitable for critical biopharmaceutical and fermentation applications across Australia.

Regulatory Compliance and Safety Assurance

Aegivast™ ACE Vent Filters meet a comprehensive set of international regulatory requirements:

• USP <788> for particulate matter in injections
• Defined as non‑fiber releasing under 21 CFR 210.3(b)(6)
• FDA 21 CFR Part 177–182 (Indirect food additives)
• Free from animal‑derived components

Each filter also features a unique product serial number tracking system to support traceability and quality documentation.

Typical Applications
