Fans of a long life

Axial flow fans combine an integral filter or alarm circuitry with a long lifetime.

The latest addition to the comprehensive family of fans from Oriental Motor is an axial flow unit that combines an integral filter or alarm circuitry with a long life fan.

In many instances, the very location of a fan renders it inaccessible once the host equipment is in operation.

For such applications, Oriental Motor has introduced the MDE Series long-life fan, which is designed to provide a lifetime of 100kh or more.

Measuring only 120mm square by 25mm deep, the MDE operates from 12 or 24V DC, and carries CE, UL, CUL and Demko approvals.

Where the uninterrupted cooling of equipment is of vital importance, the company offers two, purpose-designed fans.

Model MRS series is designed to activate an alarm when the fan speed falls to within 8.5% of 1800rev/min.

Ten versions are available in frame sizes ranging from 119mm square by 25mm deep, to 250mm square by 120mm deep, and these deliver an airflow and static pressure of up to 24m3/min and 86Pa, respectively.

Versions for 12/24V DC, 230V AC or 115V AC operation are available.

Model MD series is designed to deliver an alarm in the event that the fan stops altogether.

It is available for 12 or 24V DC operation, in frame sizes between 42mm square by 10mm deep and 120mm square by 25mm deep, delivering an airflow of up to 2.7m3/min, static pressure up to 86Pa.

A more powerful version of Oriental Motor's popular MRS Series axial flow fan has also been introduced, to meet demands for frame sizes between 160 and 250mm.

Designed for AC mains operation at 230 or 115V, it provides an alarm function to detect a drop in speed of +/-3% and, in the case of 50Hz models, delivers an airflow typically of 21m3/min at 2900rev/min, static pressure 32Pa.

A Variflow version is also available for air flow regulation.

All versions are CE and CUL approved.

Completing this quartet of introductions is the FM Series filter fan, which is designed to provide cooling to IP55 and particulate protection to IP43 requirements, typically in equipment cabinets.

Available in suction or exhaust versions, the FM Series is extremely flexible: the fan may be supplied separately from the filter and cover, allowing them to be installed separately in the host cabinet to ensure that internally-circulating air is free from dust and other particulates.

Three sizes are available, delivering up to 1.37m3/min at 3000rev/min, static pressure 63Pa, from power supplies of 230 or 115V AC.

The Series is RoHS conformant.
