SystemAir Revolution Vector EC Fans are the gold standard in growroom ventilation – they represent a genuine leap forward in both efficiency and controllability.
EC stands for “Electronically Communicated”. This means that instead of the current motor and bearings type fan that wear down over time and are not that efficient, EC fans are powered by pulsing magnets that are friction free and hence much more efficient.
This new technology has three main benefits. The first is that as there is no motor and bearings/brushes, the amount of electricity they used is 30-40% less than with a traditional fan. Secondly they are more powerful under pressure and better able to deal with pulling through carbon filters and runs of ducting.
However, the really big thing from a grower’s point of view is that you can control the speed of the fan from 1% through to 100% power, without any of the previous issues of humming, minimum idle speeds etc. The current fan speed controllers on the market all make the best of a bad situation, most fans are simply not designed to be turned down, doing this is basically a work around. The Vector EC Fans have no such issues and therefore offer complete control via the GAS EC Fan Controller – you can go right down from 1% and back up to 100% quickly, quietly and safely.
In fact, it’s not possible to use these fans without the controller, they are designed to be used with them. One controller can control as many fans as you want, you simply need to add one Y-Splitter for each extra fan you want to run.
An example setup would be a 200 Vector EC Fan for the exhaust fan and a 150 Vector EC Fan for the intake. To run these to fans you only need one controller, and one Y-Splitter. The Y-Splitter comes either as a short stub, or with a 5M extension cable (the 5M cable can also be purchased separately).
If you do choose to run two fans there is also a product available that allows you to change the speed of the exhaust and intake fans separately, called a Balancer. They are not really necessary but if you require really precise control over the negative air pressure in your room they are not too expensive and worth considering.
The GAS Controller is supplied with a 5 metre lead for connection to the Vector Fan, and the temperature probe is also on a 5 metre cable. The power lead for the fan is 2.5 metres.
At first these fans look a bit complicated to use, but they reality they are plug and play. We’ve included lot’s more info below in the FAQ’s, have a read through and if you still have any questions just give us a call.
