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
 PLEASE NOTE: RVK FAN NOT INCLUDED. SOLD SEPARATELY

Systemair Revolution Vector EC Fans

£289.95£379.95 incl. Vat
More Efficient, quieter and smaller than traditional duct fans. Simply the most efficient duct fan in the world!
 
The Revolution EC Vector fan uses the latest state-of-the-art EC technology. The brushless motors are more efficient than traditional motors - and at half speed they use less than half the power, unlike AC motors.
 
Control and protection electronics are built into the fan.
 
• Flow optimised free running plastic impeller
• The impeller is balanced to reduce vibration and noise
• Use less than half power at half speed
• Maintenance free and reliable quality - Made in Germany
• 5 Year Guarantee
 
You will need a G.A.S. fan speed controller to run this fan. The G.A.S. can regulate multiple fans using Y-Splitters, but it regulates the fans at the same output percentage levels. If you intend to run an intake / extraction set-up, we recommend using a smaller fan for your intake than for your extraction, which will maintain negative pressure in the room, preventing unwanted odours from seeping out. A balancer unit is available that allows you to regulate fans at different output percentages, which is useful if you want to use an intake fan that's the same size as your extraction fan.

  • Handmade in Europe
  • Comes with a machine washable pre-filter
  • 18 month guarantee
VIRGIN ACTIVATED GRANULAR CARBON The virgin carbon is activated at temperatures above 1000°C in a humid environment. The process opens the pores of the carbon to give it incredibly high absorption properties of organic particles and other airborne pollutants. The carbon is produced to very high standards in Europe, unlike Chinese filters which often contain cheaper blends and risk water contamination during shipping. Being produced in the EU enables better quality control.The carbon is produced to EN12915 which means it is pure enough to be used in food and drink applications. The size and depth of our filter has been specially designed to provide the correct contact between the contaminated air and carbon.The carbon is double sieved to remove any dust particles which would restrict air flow. Each CarboAir filter is guarantee to a minimum of 18 months because the carbon is pure.All filters are batch tested at source to make sure it passes our quality requirements. FILTER HOUSING The filter mesh is 55.5% open for the best air flow through the filter. Carboair filters have better flow rates, enabling them to utilise a thicker carbon bed compared to competitors. The top flange and bottom flange are preformed and made of the same strong galvanised steel. The carbon is machine packed as tightly as possible into the housing without crushing the carbon granules. The carbon is placed into the casing and put on tremor plates that have precise frequency to vibrate the carbon into a tightly packed uniform filter. A high density foam collar is placed onto the carbon bed before a top plate is added on top of the foam collar. This is then machine compressed, reducing the foam collar to less than 5mm thick. This unique process ensures the carbon will not move or settle. A top flange is fitted, this compresses the carbon further. The whole process is carried out by hand and visually inspected during each stage. The carbon filters are then packed directly into bags and boxed in the factory ready for shipping guaranteeing you receive the best quality filter every time.It has an industrial galvanised steel filter casing. Using the highest quality materials enabled it to use the finest mesh.
