Description
Everything you need to set up grow room extraction from scratch, in one box. The Air EC Fan handles the air movement, a CarboAir 50 Carbon Filter handles the odour, and the ducting, clips and power lead are all matched to size and included — no working out what else you need to order.

Why An EC Fan
- Full speed control — run anywhere from 0–100% with no humming or buzzing at low speed, unlike an AC fan on a transformer controller.
- Lower running costs — EC motors use around 40% less power than an equivalent AC fan at full tilt, and far less again when dialled back.
- Easy to clean — the blades and motor come out without disturbing your ductwork.
- Room to upgrade — compatible with the full G.A.S EC controller range if you want thermostatic control later on.
We build the identical kit around the entry-level AC fan — see the Air AC Fan & CarboAir Extraction Kit. It costs less up front and goes all the way to 12", but the AC fan has no speed control built in, so you would need to add a separate Triac controller to run the room below full output. At 500 m³/h the AC draws 60W against this fan's 35W, and 200W against 140W at 1500 m³/h.
The Fan Explained, By The People Who Make It
Ian from Global Air walks through the Air EC fan — how the EC motor differs from a standard AC fan, what the speed control actually does, and how the unit strips down for cleaning.

Which Size Do I Need?
Work out your grow space volume in m³ (Width x Length x Height), then multiply by 60 to get the air movement needed per hour to refresh the room every minute. Add headroom if you are running in a warm loft or through summer. It is generally better to over-spec the fan and dial the output back on the controller than to run a smaller fan flat out around the clock.
Common Questions
Does the kit include a speed controller?
Yes. Every Air EC Fan ships with a manual speed controller in the box, so you can set the fan anywhere from 0–100% straight away. For automated, temperature-reactive control you can add a G.A.S EC1 Fan Controller separately.
How long does the carbon filter last?
A CarboAir 50 typically gives 12–18 months of use depending on humidity, run hours and how heavily it is loaded. Fitting a pre-filter sleeve and keeping humidity under control both extend its life. Replacement sleeves are available in every size.
Is 5m of ducting enough?
For most tent and single-room setups, yes — 5m covers filter to fan and fan to outlet with room to spare. If you are venting through a loft or across a larger room, 10m combi ducting is available separately.
What if I need a 12" kit?
The Air EC range tops out at 10". For a 12" system, use the Air AC Fan & CarboAir Extraction Kit, which runs from 4" all the way to 12".
Do the jubilee clips fit every size?
Yes. The kit ships with universal jubilee clips that adjust from 1" to 12.4", so the same clip works on a 4" kit or a 10" kit.
