> Aspirating Smoke Detection
Automatic Purging Unit
ASD systems continuously monitor the air in a protected environment, potentially subjecting the system to contamination over time. In order to prevent the build up of pipe or aspiration hole contaminants, regular ASD system purging with compressed air is essential.

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.
