The pinnacle of current fan technology,  Mountain Air® EC Whisper Silencer High-Speed Fans represent the ideal solution for those looking to combine high performance with whisper-quiet operation. The dual impeller and turbine-style inlet are designed to optimise pressure throughout the fan housing, improving airflow when paired with long or complex ducting runs. Courtesy of the insulated housing, the EC Whisper High-Speed fan delivers class-leading performance whilst remaining near-silent even at full power.

• Air transfer or extraction
• Class leading performance
• Duel impeller and turbine style inlet
• Professional and hobbyist gardens
• High power output with whisper-quiet operation
• Ideal for systems requiring shorter ducting lengths
• Optimised pressure within fan housing improves air flow

​

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.
