Stratos fans push the limits of what's possible with AC motors in terms of power and efficiency. They feature fully sealed cases and blades designed to reduce friction on the sides of your ducting, increasing airflow while lowering noise levels. We've paired these fans up with Systemair approved (60mm bed) CarboAir filters, which allow air to flow more freely through your extraction system, and we've also added acoustic ducting to keep noise levels to a minimum.

• Revolution Stratos and CarboAir - designed to match each other perfectly
• Large 60mm bed depth with coarse, activated carbon (for longer contact times)
• Offers excellent airflow rates
• Compatible with regular AC fan speed controllers
• Sealed fan unit to eliminate air leaks, helping to contain smells
• Includes Acoustic Ducting, reducing noise levels

Which Size Kit Do I Need for My Grow Tent?

Find out the volume of your grow space in cubic metres: width x length x height = volume.

For example: 1.2m x 1.2m x 2.0m = 2.88m3

You'll need to have the capacity to replace this volume of air once per minute. Multiply the volume figure by sixty to work out the airflow needed per hour.

2.88m3 x 60 = 172.80m3

Carbon filters add some extra load to your fan. To account for this, multiply the required airflow by 1.2, which will give you some spare capacity.

172.80m3 x 1.2 = 207.36m3

Note that it is always better to over-spec your fan and regulate it with a controller. This gives you the flexibility to increase output levels if temperatures rise.
