    FEATURES

    • Blowing pressure can be changed by moving the adjustable pressure control disc.
    • Blowing medium can be superheated steam, saturated steam or compressed air.
    • A unique floating disc design allows for proper sealing of the blowing medium during temperature change.
    • Effective control of the start stop position of the venturi eliminates boiler tube erosion.
