Automatic Purging Unit

F-B0-AFE70-2

The FAAST Automatic Purging Unit provides a fully integrated and compact solution with user-selectable preventative or event triggered purging programs. An intelligent and installation-friendly design ensures AFE70-2 is a cost effective and reliable means of preventing pipe network contaminant blockages.
In contrast to conventional purging systems, Honeywell’s compact and user-friendly AFE70-2 unit features a single built-in Solenoid valve, which initiates the release of air into the ASD system. This valve also increases reliability by protecting the unit from any compressed air damage and can be accessed through a control board that is integrated into the housing.

  • A fully integrated and compact system, designed for larger pipe networks
  • Designed for use in Honeywell Aspiration Smoke Detection ( ASD) systems
  • Patented design without air resistance (as defined by EN 54-20)
  • 6 user selectable preventive or event-triggered purging programs - Short or long purging cycle options
  • Internal clock or external clock timer can be connected
  • Several systems can be coupled in Master-Slave mode
  • Manual control via external push-button
  • Automatic initiation if a fault message is received from the ASD system (activating through FACP only)
  • Easy commissioning without software tools
  • Multicolored LED indicates the system condition
