Orion Fans OA280EC Series with 0-10V PWM and Tach EC Fans

Orion Fans OA280EC Series with 0-10V PWM and Tach EC Fans offer high-performance cooling with energy-efficient EC motors in 115V and 230V models. These fans are designed with a durable die-cast aluminum frame and UL 94V-0 rated plastic impeller. The OA280EC fans deliver up to 1135CFM airflow at low noise levels and operate efficiently across a wide voltage range of 100VAC to 125VAC or 150VAC to 270VAC, at 50Hz/60Hz. These AC fans feature a 0 to 10V voltage range and PWM speed control, tach output, and a long life expectancy of 70,000 hours. The OA280EC EC fans offer low power consumption and energy saving with a 280mm x 90mm dimension. These EC fans are ideal for appliances/white goods, building automation, HVAC/refrigeration, oil and gas, industrial automation, and renewable energy.
