Features:
Dual Switch Options (N C/NO) – The LCF013 features both Normally Closed (N C) and Normally Open (NO) mechanical switch types. N C models open contacts upon airflow detection (triggering alarms/indicators), while NO models close contacts when airflow is present.
Reliable Airflow Monitoring – Designed to detect fan failure or filter blockage, this airflow monitor signals air loss in ventilation ducts, fan systems, or filter units, regardless of airflow direction.
Simple Mechanical Operation – A lasting, non-electronic solution for airflow monitoring, guarantee reliability without complex wiring or power requirements.
Compact & Easy Installation – Its small size allows flexible mounting in ducts or near fans/filters, with straightforward connection to alarms or indicator lights.
Safety Note – for Max. rating: 10W (do not exceed). Requires contact protection circuits for inductive/capacitive loads to prevent voltage/current spikes.
