  • Oil Well Survey Instrument Company

    Model VS-DC Short Retractable Soot Blower is a short travel, approximately 10 inches, retractable type unit used primarily for cleaning slag from the boiler wall tubes.


    • The soot blower can either be driven by electric motor, air motor, or manual operation.
    • Mounting of the soot blower is flexible in that it can be mounted conventionally with the poppet valve straight down, out to the left or straight out to the right.
    • 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.
