These 0.2 Micron Air Filters have a fine enough filter membrane that they can filter out microbes and bacteria. They can be used with any oil free air compressor such as a pond pump, or other type of pump. They can also be used as an airlock in the top of your fermenter or used to filter air going back into a cask when dispensing real ale.
This filter is not suitable for liquids and should be discarded if it gets wet.
Compatible with 4 mm ID EVABarrier tubing. You will need to heat up the tubing and use needle nose pliars to widen the inner diameter. No hose clamp required.
