SystemAir Revolution G.A.S Digital EC Fan Balancer
The G.A.S EC Fan Balancer has been specifically designed for use with the SystemAir Revolution Vector EC Fans and G.A.S EC Fan Controller.
Designed to regulate the difference between your SystemAir Revolution EC Vector fans. Allowing the use of similar sized extractor and intake fans.
If your intake fan is smaller than your extractor fan, you can run your fans at the same speed and still get the negative pressure your grow room needs.
Though EC fans cost more to buy, their running costs are so much lower that within about a year (dependent on fan size, speed and use) you’ll have made your money back.
After that it’s save, save, save. And you’ll have a much better fan!
