G.A.S Pro Step Fan Controller — 5-Step AC

G.A.S Pro Step Fan Controller — 5-Step AC Controller

A silent, digital 5-step AC fan controller that solves the common problem with cheaper controllers — the constant clicking and humming between speed settings. The Pro Step uses solid-state relays and digital controller technology for truly seamless transitions. European-built, designed for growers who want pro-level fan control without the complexity of temperature-triggered systems.

Why growers choose the G.A.S Pro Step:

• 5-step speed control — precise increments, not a crude analogue dial
• No clicking, no humming — solid-state relays switch silently, unlike mechanical step controllers
• Digital controller technology — more reliable than older voltage-dimming designs, less heat generated in the controller itself
• Made in Europe to high quality standards — proper CE compliance, not cheap imports
• Simple, set-and-forget operation — dial in your preferred step, walk away
• Compatible with standard AC inline fans — RVK, Krystal, Iso-Max and similar

Who it's not for:

For EC-commutated fans like the HyperFan range, you need an EC-compatible controller — this is AC only. If you want automatic temperature-triggered fan speed changes, step up to the G.A.S Pro Plus or Enviro Controller V2. Not compatible with LED lighting control.
