An inline sanitary filter that filters down to .027 micron with a 99.99% efficiency. Use it anywhere you need to keep something sanitary. Both 1/4" and 3/8" tubing will attach and it will snugly fit in any standard stopper as well. Check out this list of suggested uses:
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, like the Fermentap and our own Stainless Conicals, where displacement 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. Not appropriate for long term storage of beer or wine as it is not an oxygen barrier.

Inline Aeration/Oxygenation Filter: With an oxygenation or aeration sytem, such as our FE375 or FE380, it will filter contaminants out of oxygen or air. It is connected inline between pump/O2 tank and s/s 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.

Storage: Store in Ziplock bag in a dry place with minimal moisture exposure. Can last up to 1 year. Discard if there are any signs of discoloration.

About the inline filters: There are two sides to the filter - an "in" and an "out". The direction you use doesn't matter, however, you want to take note of which way you first push air through it and always keep it that way. There is an arrow on the edge of the filter housing that we use to keep the air flow going one direction when using it. The filter should never get wet, so don't try and sanitize it by dunking it in sanitizer. If you want to clean the outside of it, use Alpet D2. To store the filter, use a little tinfoil on the "In" of the filter and store in a zip-lock bag.

Dose anyone know how many uses/how often this needs replaced when only used to start siphons?

BEST ANSWER: This filter can last up to one year and should be discarded if there are any signs of discoloration. It is important to never get the filter wet and to store it dry at all times.
What is the maximum safe pressure for this filter? Using it for CO2/N2 draft air filtration.

I am using this to create a simple. sanitary siphon with a two-port carboy hood and a racking cane. This system greatly simplifies my setup and cleaning when racking to a secondary fermentor or bottling bucket. There are lots of other uses for this handy little filter as well.

make sure that you mark with a sharpie the side that faces the pump so that you hook this up in the right direction each time. My understanding is to keep this as a sanitary filter, you have to push air the same direction each time. Also..this filter will find any moisture in your hoses so make sure they are dry before you hook up. Great filter easy to use, but make sure you have the right size hose if you are going to use this with the Whisper aquarium pump.

Great sanitary filter.
This is great to add to a two port carboy cap and create a sanitary siphon. Place a racking cane in one port and this in the other. Blow through the sanitary filter and the racking cane will start siphoning. I saw the in a BYO magazine the other day and it works great. I like it better than the auto siphon because all you have to do clean the cane, not the whole auto siphon.

Does What It's Supposed To Do
It just works, nothing fancy

Use this with both O2 and Co2...
I use this as an adapter for both my O2 wand for oxygenation and for CO2 for sterile/closed transfer with my Better Bottles at very low pressures. Works well and easy to use.

A must have for filtering and aeration.
Easiest thing to help clean the o2 and or Co2 before aeration. It is such a simple peace but a must have not to mention, It's Cheap!
