View Full Version : In line air filters

We have a air compressor running our bottling line at 125 psi. We are worried about contaminated air coming from the compressor. There are a ton of products on the market. Does anyone have experience with any of them?

Thank you,

Ideally, the air shouldn't be getting anywhere near the beer itself. YOu should be using CO2 or nitrogen (less common in small setups) in the filler bowl and as BBT top pressure gas. Only use the compressor air for driving valves, pumps etc with a bomproof diaphragm between it and the beer if the design forces you to have this set up. Ideally the air should stand no chance of getting near beer.

The air needs to be dry, particle free, and normally oil free.

If you are using it in contact with wort or beer, it needs to be rust free, odour free, moisture free, oil free, and just about any other contaminant free (e.g. other petrochemicals), and last but not least, sterile.

Great new book from the MBAA called "Compressed air in the brewery". Should answer all your questions and then some! Good luck!
