0.2‑micron sanitary air filter, 6–10 mm barb

This sanitary filter is a physical barrier against microscopic contaminants. It is mainly used during wort aeration before pitching, or to replace the water in a traditional airlock during pressure transfers. Its hydrophobic membrane allows gases to pass while retaining harmful microorganisms, ensuring impeccable hygiene at the heart of your fermentation process.

Why choose this product?

• Microbiological safety: 0.2‑micron filtration is the standard for removing airborne bacteria and particles.
• Versatile use: Compatible with air pumps for oxygenation or for cooling closed vessels.
• Easy installation: Its stepped barbs allow direct connection to most flexible tubing (silicone or vinyl).

Technical specifications

• Filtration threshold: 0.2 µm.
• Material: Food‑grade polymer body and filter membrane.
• Connector dimensions: Barbed fittings compatible with 6 mm, 8 mm and 10 mm ID tubing.
• Property: Hydrophobic (does not allow liquids to pass under normal use).
• Direction of use: Bidirectional (although often used in a fixed direction for gas).
• Not included: Flexible tubing, air pump, diffusion stone.

Technical Tips

• Maintenance: This filter cannot be sterilised in an autoclave or with boiling water. Replace it regularly, especially if it shows signs of moisture or discoloration.
• Prevention: Ensure that no liquid (wort or sanitizer) comes into contact with the internal membrane, as this could block airflow.
