HIGH QUALITY Made of food-grade stainless steel, our 0.5-micron aeration stone is corrosion-resistant, durable, and able to withstand high temperatures for long-lasting performance. POWERFUL FEATURES The 0.5-micron pore size produces fine, consistent bubbles for efficient gas transfer, ensuring even diffusion with no clogging and strong resistance to corrosion, helping enhance the wort fermentation process. HOW TO USE Always turn on the gas supply before inserting the aeration stone into the liquid. Attach the aeration stones barb to a 1/4 inch inner diameter hose, and connect the other end of the hose to the in or gas-side post of a regulator or CO2 tank. Operate at low pressure, ideally between 35 PSI. IDEAL FOR HOME BREWING Compared to 2-micron stones, the 0.5-micron aeration stone generates smaller, finer bubbles, improving oxygen or carbon dioxide dissolution in liquid. Enhances the quality of draft beer, soda, cold brew coffee, and other beverages. USED FOR Suitable for oxygenating wort before fermentation, force carbonating beer, soda, or juice in kegs, and aerating cold brew coffee systems.
