31.5mm wide vacuum unit is designed to optimize the control of large vacuum flows.

  • The twin-nozzle type is the most durable unit for applications with longer suctioning or transportation time.The large nozzle controls vacuum generation from start up to a prescribed reference preset pressure level, after which the small nozzle takes over for maintaining a vacuum level. This combination makes possible substantial reductions in Air consumption.
    Only one signal is used for vacuum generation as with previous models
  • The two-stage nozzle type's vacuum suction rate has been increased by approximately 40% compared to conventional types. The vacuum suction rate has been increased by 40% compared to PISCO Vacuum Generator complex type with single nozzle.
  • With the pressure sensor, the cost-effectiveness has been pursued (in-house comparison) and a high level of visual recognition has been realized.All settings can be made using just three push buttons.
    Four different display units are available.
  • The single-nozzle type is an orthodox, complex vacuum generator designed to produce large vacuum flows.
  • A wide variety of valve type is standardized. ・Single-nozzle type:Normally open, Normally closed, Double solenoid (retention) type

    ・Two-stage nozzle type : Normally open, Normally closed type

    ・Twin-nozzle type : Normally closed type
