GTS VM-Venturi Mixers are proportional air-gas mixers designed for efficient and consistent fuel-air mixing in industrial combustion systems. Operating on the Venturi suction principle, combustion air flowing through the Venturi throat creates suction that draws fuel gas into the mixer. The gas-to-air ratio can be adjusted using the integrated gas throttle valve, allowing precise mixture setting and reliable combustion across a wide range of airflow conditions. The compact and heavy-duty design provides dependable operation for premix burners, pilot burners and low-pressure gas combustion systems. The GTS Venturi Mixer is compatible with Natural Gas (NG), LPG and other suitable fuel gases, subject to gas composition verification. It provides practical heat input control and stable air-fuel mixing for industrial heating applications.
