Global Air Supplies

About

Global Air Supplies – G.A.S. – started in extraction and has since taken on Nutriculture , so the range now covers both sides of a grow room: the air handling and the hydroponic systems. Extraction and air handling AC inline fans – the straightforward option. Single or twin speed, reliable, cheapest per m³/h. Silenced and box fans – motor and impeller inside an insulated housing. Substantially quieter, which is what matters in a flat or a bedroom. EC fans – brushless motors with fully variable speed, far more efficient at part load and genuinely quiet turned down. See EC fans . Systemair RVK – the Swedish-built fans G.A.S. distribute in the UK. Controllers to drive fans on temperature or humidity rather than a fixed speed – see fan speed controllers . The Nutriculture systems Nutriculture is no longer a separate company – its product lines now sit under Global Air Supplies. The systems are unchanged and the spares still fit: Ebb & Flood (EF100, EF120, EF230, EF420, EF620) – tray-based flood and drain in five sizes. See flood and drain systems . Flo-Gro – their dripper system. See dripper systems . ATU auto top-up kit – keeps reservoir level constant without you topping it by hand. BubbleGen – oxygen water circulator for reservoirs. See air pumps and air stones . The sister brands Several ranges that used to sit under the Nutriculture name have their own pages: Origin Systems for their modern dripper systems, X-Stream for aeroponic propagation, Gro-Tank for NFT, Oxypot for DWC and Vitopod for modular propagators. Sizing extraction Work out the room volume in cubic metres and aim to change the air roughly once a minute, then add 25-50% for the resistance your carbon filter and ducting add. Fan and filter diameter must match. Why buy Global Air Supplies from The Hydro Bros? We are a hydroponics shop in Croydon and we size extraction and build these systems every day.
