Our propeller fans are available with an integrated alarm system designed to notify you of any irregularities, such as a decrease in the fan's airflow capacity or a complete shutdown of the fan.
(1) Low-speed alarm
If the fan motor speed drops due to its lifespan or the presence of foreign matter, an alarm will be output. Since the drop in speed can be detected, arrangements can be made and replacement can be made before the fan motor stops. This helps with predictive maintenance.
(2) Locked Rotor Alarm
The fan will emit an alarm when the fan rotation has stopped. This will alert you to interruptions immediately, so that action / replacement can be made.
