Revolution EC Extraction Kits

EC fans are much cheaper to run 

How? They use less power at slower speeds, unlike AC fans, which always run at full power. The slower the speed, the bigger the saving.

The fan's body is a single piece that's completely air tight.

These fans are the first ones with directional air flow, which means the air travels down the ducting efficiently without losing pressure. 

To stop heat problems, the motor has overheating protection and the body is made from a unique composite material.

The impeller is balanced twice to stop vibrations and reduce noise. A mounting clamp is included to further prevent vibrations.
 

They may be powerful, but these fans are wrapped up in a light, comnpact body that's easy to fit. 

If there's a sharp temperature spike, your controller builds speed quickly. If there's a slight temperature rise, it builds speed slowly.

This corrects sudden spikes quickly without overdoing it when there's only a slight change.
