Description:May be used to design your own oxygen system. This adjustable regulator works with disposable oxygen cylinders, which can be found at hardware stores. Using pure oxygen is by far the most effective way to oxygenate your wort. Most brewers notice improved yeast health and attenuation after they switch to pure oxygen.
Good I have this. Really does make a difference in fermentation process. Just adding a minute of oxygen into your wort makes the yeast seem to work so much faster and more complete. Would recommend.
