Gorilla GXi 6 Wireless Inline Fan | 402 CFM 6 in EC Duct Fan

402 CFM at 32 dB-A Is What the GXi 6 Is Built For

Six inches is the size most 4x4 and 5x5 tents settle on, and the GXi 6 is aimed squarely there. It moves 402 CFM on a 60W EC motor drawing 0.50A at 120V. PWM control is what lets it hold a low speed smoothly instead of stepping between fixed taps. Noise sits at 32 dB-A. Run it at half output behind a loaded carbon filter and it disappears into the room. Nothing hangs on the wall but the duct.

Running a Grow Tent Inline Fan Without a Wall Controller

The controller lives in the fan, so the app sets speed and schedules. Day and night settings shift output when lights go off, which keeps night humidity from creeping. Temperature and humidity automation is a step further and needs the GXi sensor, sold on its own. On its own the fan is a smart speed controller, not a climate controller. It takes 120-240VAC and ships with a five-foot cord. Certification is FCC, not UL or ETL, so check that against your local requirements before a permitted install. Support the housing on both sides so the duct collars carry no weight.

Key Features

• 402 CFM at 6 in: The usual fit for a 4x4 or 5x5 running through a carbon filter.
• 32 dB-A: Quiet at full, and close to inaudible at half output.
• 60W PWM EC Motor: Holds low speeds smoothly instead of stepping between fixed taps.
• Controller Built In: App speed and scheduling with no wall unit to mount.
• Day and Night Settings: Drops output at lights-out to hold night humidity down.
• 120-240VAC Input: One model covers either supply voltage.
• Sensor-Ready Automation: Pair the GXi sensor to drive speed from temperature and humidity.
