Draft Beer Gas Blenders

Precision Gas Blenders for Long Draw & Nitro Draft Systems

Getting your gas blend right is the difference between a perfect pour and a service problem. Gas blenders mix CO2 and nitrogen to a precise, consistent ratio — eliminating the guesswork of manual regulator adjustments and ensuring every keg pours the same way, every time.

Why You Need a Gas Blender

• Long draw systems require a CO2/N2 blend (typically 70/30) to maintain carbonation over extended beer line runs without over-carbonating
• Nitro beers (stouts, nitro IPAs, cold brew) require a high-nitrogen blend — usually 75/25 N2/CO2 — for the characteristic creamy, cascading pour
• Mixed-gas systems eliminate the need for separate pre-blended cylinders, reducing gas costs and cylinder management
