This versatile little filter is a beer maker's insurance policy! Whether you’re aerating or racking you will appreciate having the peace-of-mind of knowing that your brew will not be contaminated by whatever is floating around in the air. Use it anywhere you need to keep something sanitary. Both 1/4"" and 3/8"" tubing will attach to it, and it will snugly fit in any standard stopper as well.

• Airlock: The most common use might be as an airlock on any kind of fermenter. Unlike other small sanitary filters, this unit fits perfectly into a stopper. Works great for conical fermenters where air is taken in when samples are taken or trub is dumped. Using the sanitary filter as airlock also eliminates the concern of drawing air back in as hot liquid cools and contracts in a fermenter. It is not appropriate for long term storage of beer as it is not an oxygen barrier.
• Inline Aeration/Oxygenation Filter: With an oxygenation or aeration system, such as our FE375 or FE380, it will filter contaminants out of oxygen or air. It is connected inline between pump/O2 tank and Stainless Diffusion Stone.
• Hand Pumps: Some breweries use this filter with the breweries hand pump system. Air going back into the cask is sanitized through this filter. This has extended shelf life of Real Ales by up to 2 weeks!
• CO2 Filtration: Used inline with your CO2 Kegging setup, this piece can be used to filter out any potential contaminants from your CO2 Tank.
