A gas and air mixing mixer used for combustion in gas burners. The structure is a venturi mixer that adjusts the flame power while maintaining the mixing ratio.
**Structure of the Mixer** The Venturi mixer utilizes the negative pressure generated when air blown from the combustion blower passes through the nozzle inside the mixer to draw in and mix gas. The mixed gas is supplied to the gas burner connected by piping for combustion. **Corresponding Gas Burners** Various premixed burners (forced mixing burners) Our burner models: SR, SF, FF, CBX, UL, pipe burners, pian burners, BS, metal knit burners (MNB), metal mat burners (MFT), surface combustion burners, and many others. **Advantages** Combustion adjustment is easy. Since the fuel gas is adjusted to atmospheric pressure by a zero governor, control of the gas line is unnecessary, and combustion can be controlled solely by the control of the combustion air line. The gas flow will increase or decrease in accordance with the air flow, allowing the air-fuel ratio to be maintained at a constant level. Components can be disassembled, providing excellent maintenance and making inspection and cleaning easy. We offer piping sizes from 15A to 80A, suitable for various capacities of burners.
