A family of Electronically Commutated (EC) fans offers low power, energy-saving cooling for ac applications. The ac-input fans utilize a brushless dc motor and incorporate voltage transformation within the motor for significantly lower power consumption. This equates to power savings of up to 50%, enabling customers to meet energy-consumption requirements from agencies like ENERGY STAR.
Available in a range of sizes (60 mm, 120 mm, 172 mm and 250 mm), the EC fans are ideal for a broad range of applications including appliances, commercial and 
process control, refrigeration, HVAC, electronic enclosures and cabinets. Most models are available with a universal voltage range and the 250-mm fans are available with dual speed functionality in 115-Vac and 230-Vac versions. By maintaining the same interface between the fan and equipment, EC fans can be used as drop-in replacements for equivalent-sized ac fans.
The EC Fan Series also includes 60-mm, 120-mm and 172-mm models with IP68-ATEX ratings for applications involving explosive atmospheres or flammable gases.
The OA200EC Series of 250-mm fans feature dual-speed control (1,400 RPM and 2200 RPM) with airflow values of 300 CFM and 480 CFM respectively. For custom requirements, the OA200EC can have the speed control limits programmed at the factory to deliver even more power savings.
“Energy conservation is of increasing importance in today’s world. Replacing existing ac fans with advanced energy-efficient EC Fans results in a substantial reduction in energy usage and cost,” said David Luna, VP of Marketing for Orion Fans.
Already used in electronic cabinets, air-conditioners, refrigerators, chillers, range hoods, ventilation systems and more, EC fans start at $26.00 in small quantities.
