McDantim Dual CO2 Trumix Gas Blender - Precision Nitrogen & CO2 MixingThe McDantim Dual Trumix Gas Blender is the professional standard for commercial draft systems serving both standard beers and nitro stouts. This blender accurately mixes pure Nitrogen and CO2 to two specific ratios: 25% CO2 (for Nitro stouts) and 70% CO2 (for high pressure push systems). This eliminates the need for expensive pre mixed cylinders and ensures your gas ratios remain consistent, preventing over carbonated or flat beer. Technician's Note:
