G.A.S (Global Air Supplies)

Quiet extraction, built as one system.

GAS build the fan, filter, controller and cable, so a Revolution or Phresh fan plugs straight into a GAS Enviro.

Nothing matches all of those filters.

G.A.S — Global Air Supplies extraction

G.A.S is a dedicated ventilation brand covering the full extraction chain — fans, controllers, humidifiers, ducting and the small parts that connect them — engineered specifically for quiet, efficient grow room air handling rather than repurposed industrial gear.

The range spans the Air EC Fan and Air AC Fan (formerly RadAir) inline extractors, SilencedAir duct silencers and DiffuseAir fan diffusers for noise control, the Global Air Intelligent VPD Humidity Controller and AC Pro step fan controllers for automated climate control, plus Sonic Air humidifiers, aluminium and combi ducting, and timers. Revolution extraction kits and Rhino filters sit alongside the core G.A.S line in this collection too.

Building a full G.A.S setup

Because the fans, controllers and accessories are designed to work together, a G.A.S fan paired with a G.A.S controller and silencer is the simplest way to get a matched, quiet extraction chain without cross-checking specs between brands. If you're starting from scratch, our fan and filter sizing guide gives you the m³/h figure to work from, or browse extractor fans and fan controllers to compare against the rest of our range.
