The MDA Series axial fans feature a built-in alarm circuit that the host controller can recognize if the fan speed drops. This is important for noticing quick drops in the cooling capacity of the fan caused by a service life of the fan or by the ingress of a foreign objects.

• High-Performance, Alarm-Type
• DC Input
• Frame size 2.44 in (62 mm)
• Maximum airflow 17.7 CFM (0.5 m³/min)

The MDE Series long life axial fans have a 100,000-hour life expectancy lowering maintenance costs and reducing downtime. They feature built-in alarms that detect and signal fan rotation abnormalities or stoppages. These fans meet UL standards and CE Markings (EMC).

• Long-Life Models (up to 100,000 hours)
• DC Input
• Frame size 2.36 in. (60 mm)
• Maximum airflow 18.7 CFM (0.53 m³/min)

These compact axial fans use high-performance brushless DC motors. They are optimal for cooling equipment. Built-in alarm types are also available that detect and signal fan rotation abnormalities or stoppages. These fans meet UL, CSA, EN/IEC standards and CE Markings (EMC).

• DC Input
• Frame sizes 2.36 in. / 2.44 in (60 mm/ 62 mm)
• Maximum airflow up to 42.7 CFM (1.21 m3/min)
• Alarm types available

The MDV Series DC axial fans easily allow for changes in fan speed. They employ a PWM control method by which speed is changed with a PWM control circuit (not supplied).

• PWM Control
• DC Input
• Frame size 2.36 in (60 mm)
• Maximum airflow 12.7 CFM (0.36 m³/min)
