0.5 Micrometre Stainless Steel Aeration Stone Key benefits Finer bubbles for faster gas transfer: 0.5 Micrometre pores produce much smaller, more uniform bubbles than 2 Micrometre stones or typical soda guns, improving oxygen or CO2 dissolution and supporting faster, more consistent fermentation and carbonation. Durable, foodsafe construction: Made from foodgrade stainless steel for corrosion resistance and temperature tolerance. Designed for long service life with minimal clogging. Works at low pressure: Effective aeration and carbonation at approximately 3–5 PSI, reducing the need for pressure gas and making it safe and easy to use in home setups. Product details Pore size: 0.5 Micrometre for fine, frothy diffusion. Material: Foodgrade stainless steel — anticorrosion and heat resistant. Connection: Builtin barb fits a 1/4 inch ID hose. Compatibility: Connect the hose to the 'in'/'gas side' post or to a CO2 regulator. How to use Turn on the gas source first. Attach the aeration stone barb to a 1/4 inch ID hose. Connect the other end of the hose to the regulator or gas post. Insert the stone into the liquid after gas is flowing. The stone performs well at about 3–5 PSI. Clean and sanitize before each use to maintain performance. Suitable applications (examples) Home brewing: Aerate wort before pitching yeast to improve oxygen transfer and support healthier fermentation. Keg carbonation: Produce fine CO2 bubbles for smoother, faster carbonation of draft beer or soda in kegs. Beverage infusion: Add microbubbles to carbonated drinks, cold brew coffee, or other beverages for a finer mouthfeel and more uniform gas integration. Why choose this model Produces smaller, more evenly distributed bubbles than largerpore stones. Lowpressure operation and sturdy stainless construction make it practical for most home brewing and beverage setups. Simple hose/barb hookup compatible with standard 1/4 inch ID tubing and common CO2 regulators.
