Electronically Commutated (EC) the Revolution EC Vector fans combine AC and DC voltages, bringing the best of both technologies. Easy speed controllability, efficiency, lower power consumption and higher m3/h can be achieved.

The fans have aerodynamically optimised impellers and guide vanes with integrated external rotor motors giving you optimal power and performance levels. To protect the motor from overheating the fan has integrated electronic motor protection. Revolution fans are manufactured from special composite material. There is a specially designed mounting clamp available for easy installation which prevents the transfer of vibrations to the duct.

Key Features:

• State of the art energy saving brush-less EC fan technology
• Absolutely no hum or vibration even on lower speeds
• Small loss of airflow when under pressure compared to other fans
• High Power, example RV250L EC 1520m3/h with carbon filter
• Add another fan in series to double the pressure
• One piece housing so is air tight lightweight and compact
• Quieter than acoustically cased fans when combined with acoustic ducting
• Maintenance free and reliable quality – Made in Germany

Revolution fans are more efficient, quieter and smaller than traditional duct fans. Simply the most efficient duct fan in the world.
