Plug it in, set your intake and outtake speeds independently, and stop wrestling with tent bulge. German engineering doing exactly what it should.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cp\u003eThe GAS Fan Balancer is a \u003cstrong\u003ededicated negative pressure controller\u003c\/strong\u003e designed specifically for \u003cstrong\u003eSystemAir Revolution Vector EC Fans\u003c\/strong\u003e. It connects to your intake and extraction fans, then to your GAS EC fan controller, allowing you to run two same-size fans and balance them independently. Instead of one fan fighting the other, you get precise control over negative pressure — which is the difference between a stable room and a bulging tent.\u003c\/p\u003e\n\u003ch3\u003eHow it compares\u003c\/h3\u003e\n\u003cp\u003eThere are several ways to control EC fans.

If you're starting fresh and want everything in one box, a full controller makes sense. This one's for people who just need the balancing sorted.\u003c\/p\u003e\n\u003ch3\u003eUsage guidance\u003c\/h3\u003e\n\u003cp\u003eThe balancer solves one core problem: when your extraction fan is fighting your intake fan, your tent bulges and your filter doesn't do its job properly.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStandard negative pressure setup\u003c\/strong\u003e\u003cbr\u003eRun your intake fan at, say, 70% and your extraction fan at 85%. Air gets pulled through the filter, odours stay contained, and neither fan is overworked. The balancer lets you adjust these independently in 1% increments until it feels right.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eUsing matched intake and extraction fans\u003c\/strong\u003e\u003cbr\u003eThis is where the balancer really earns its place. With two identical fans, the extraction side needs more power because the filter creates resistance. Without balancing, you either get positive pressure (tent bulges, smell leaks) or you overtax the extraction fan. The balancer lets you dial this in precisely.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFine-tuning your room climate\u003c\/strong\u003e\u003cbr\u003eNegative pressure isn't just about odour control — it's fundamental to temperature and humidity stability. Tight control over fan speeds means tighter environmental control. Pair this with a GAS Enviro V2 or Enviro4 and you've got a properly managed space.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInstallation\u003c\/strong\u003e\u003cbr\u003ePlug-and-play. Connect your intake fan to one port, extraction fan to the other, then plug the balancer into your GAS EC controller. No configuration hassle, works straight out the box.\u003c\/p\u003e\n\u003ch3\u003eTechnical specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e SystemAir Revolution Vector EC Fans only\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRequires:\u003c\/strong\u003e GAS EC fan controller to operate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFan speed control:\u003c\/strong\u003e 0–100% in 1% increments\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature display:\u003c\/strong\u003e Min\/max temperature readout in °C or °F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperation:\u003c\/strong\u003e Silent — no humming from fans or controller\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Plug-and-play, no additional setup required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWho this is for\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eGrowers running two Vector EC fans who want independent speed control\u003c\/li\u003e\n\u003cli\u003eAnyone dealing with tent bulge or positive pressure problems\u003c\/li\u003e\n\u003cli\u003eExisting Vector EC fan users looking to upgrade without replacing their setup\u003c\/li\u003e\n\u003cli\u003eSerious growers who want precision control over negative pressure\u003c\/li\u003e\n\u003cli\u003eBudget-conscious setups where a full integrated controller isn't justified yet\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eParticularly well suited to growers who understand that negative pressure is a critical part of climate control, not just a nice-to-have.\u003c\/p\u003e\n\u003ch3\u003eOur take\u003c\/h3\u003e\n\u003cp\u003eThis is a focused tool that does one job properly: balancing intake and extraction so your room breathes the way it should.
