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
Brewers Association Standard Blends
- 70% CO2 / 30% N2 — BA standard for long draw draft systems serving most beer styles
- 25% CO2 / 75% N2 — standard for nitrogen-dispensed beers (stouts, nitro ales)
- Custom ratios available with adjustable blenders for specialty applications
What We Carry

Gas Blender FAQ
Do I need a gas blender, or can I just adjust my regulator manually?
A blender gives you a precise, repeatable ratio automatically — manual regulator adjustment on separate CO2 and N2 tanks is imprecise and drifts over time, which shows up as inconsistent pours across kegs. Any system running multiple beer styles on long draw or nitro benefits from a blender rather than manual mixing.
What blend ratio do I need for my system?
70/30 CO2/N2 is the Brewers Association standard for most long draw systems. Nitro beers need the opposite emphasis — around 75/25 N2/CO2 — for the correct cascade and head. If you're running both styles, you need either two blenders or an adjustable one.
