Blow off device for pipe system – FAAST series

F-BO-AFE70-2 | Blow off device for pipe system – FAAST series

The blow-off device enables the automatic cleaning of the pipes of aspirating smoke detectors, with compressed air. Control takes place via predefined, selectable control cycles, event-controlled with contamination messages or manually via a control input. The solenoid valve controls the compressed air from a storage tank or compressor unit for short-term rinsing of the pipe system and the suction openings.

Part-No.:
F-BO-AFE70-2

Features

  • Compact service unit
  • Preventive or event-controlled blow-out programs selectable
  • Easy integration, even in inventory systems
  • 6 stored, selectable programs for cyclic cleaning runs
  • Control input for manual cleaning cycles
  • Integrated clock module for daytime-dependent cleaning cycles
  • Up to 3700l / min air flow at 7 bar air pressure
