EC-fans are up to 30% more efficient than AC-fans
EC-fans are up to 30% more efficient than AC-fans and the most efficient while partly loaded
EC motor efficiency ranges between 80% and 90%. To put this into perspective, a three phase induction motors maximum efficiency is at 75%, and PSC (permanent split capacitor) motors have a maximum efficiency of between 60% and 70%. By using an EC motor the payback is instant and can provide cost effective savings over its lifetime. You can see the example of efficiency and energy saving features demonstrated here.
EC-fans are easily controllable (0-10 V)
In terms of speed control and features, because the motor's operation is controlled by software, EC motors allow customers to optimize and integrate the motor, fan and controller with the application, and to include features like data communications, constant volume control, variable speed, etc.
AHU
An air handler, or air handling unit (often abbreviated to AHU), is a device used to regulate and circulate air as part of a heating, ventilating, and air-conditioning (HVAC) system. An air handler is usually a large metal box containing a blower, heating or cooling elements, filter racks or chambers, sound attenuators, and dampers. Air handlers usually connect to a ductwork ventilation system that distributes the conditioned air through the building and returns it to the AHU. Sometimes AHUs discharge (supply) and admit (return) air directly to and from the space served without ductwork
Small air handlers, for local use, are called terminal units, and may only include an air filter, coil, and blower; these simple terminal units are called blower coils or fan coil units. A larger air handler that conditions 100% outside air, and no recirculated air, is known as a makeup air unit (MAU) or fresh air handling unit (FAHU). An air handler designed for outdoor use, typically on roofs, is known as a packaged unit (PU), heating and cooling unit (HCU), or rooftop unit (RTU).
