High blast mixers are compact venturi mixers, which use compressed air as the primary source of oxygen and atmospheric air as the secondary source. The air/gas mixture produces a sharp, well-defined, clear blue flame. These mixers have combined with suitable burner nozzles. These mixers are ideal for applications such as ladle heating, die heating, crucible heating, flame heat treating, flame annealing and other spot heating applications. It is designed to accurately mix air and gas in the correct proportions for proper burner operation.
