Mountain Air EC Whisper Silencer Fan 150mm

HIGH SPEED EC MOTOR

This fan incorporates a digital, EC (Electronically
Com-mutated) DC motor that provides superior performance and efficiency beyond
what is possible with traditional AC motors. The High Speed motor is further
boosted by flow-conditioners that are built into the fan housing. These
conditioners work to stabilize the air as it exits the fan housing, resulting
in a more concentrated and powerful column of air.

3-MODE ENVIRONMENTAL CONTROLLER

A digital 3-mode Environmental Controller is included to
provide the user with total control.  One mode allows for manual control of the
fan’s speed, while two thermostat-controlled modes either turn off the fan, or
reduce its speed when the temperature of the room falls below set temperature.
