Diffuse Air by Global Air Supplies – Equal Air Distribution

£36.99£56.99 incl. Vat

Wave goodbye to oscillating fans as the newest ventilation system has arrived, and it is not one to miss! The G.A.S. DiffuseAir system offers you complete control over the climate of your grow room. 

The clever design of the DiffuseAir does pretty much what it says in the name! It ensures that air is diffused uniformly around the grow space, rather than being directed straight at your plants like an oscillating fan would. 

As a result your environment stays consistent, and any microclimates, high humidity zones and hot spots are eliminated. Harsh air streams that a typical fan would produce are gone, helping to decrease the chance of wind burn on the plant itself and salt accumulation in your growth media. It also rids of those inevitable cold spots that an oscillating fan would cause!

The DiffuseAir is flexible and can be used within a couple of different scenarios, though it must always be attached to an extraction fan (not included) to work.

  • Aerodynamically efficient
  •  Proven technology
  •  Ceiling hung for more grow space
  •  Improved Environment = Improved Yields
