The Revolution AC Stratos fan is an energy-efficient in-line fan with a 230V AC rotor motor. Air flow is increased using aerodynamically optimised impellers and guide vanes, all while producing lower decibels than most other fans on the market. The Stratos fan can be installed in any position with the mounting bracket. The Revolution range can handle air flow restriction such as carbon filters far better than any other fan.

The Revolution EC Vector fan uses the latest state-ofthe- art EC technology. The brushless motors are more efficient than traditional motors and at half speed use less than half the power, unlike AC motors. Control and protection electronics are built into the fan.

No significant air flow loss

The white acoustic foam is specially designed to absorb noise without restricting the air flow. The foam is certified for use in air acoustics applications and does not absorb moisture or dust.
