Vortex Inline Fans - Steel-Bodied Extraction Fans for Grow Room Ventilation
Best for: growers who need a dependable primary extraction fan to pull hot, stale air out of a tent or grow room, day in and day out.
Our thoughts
This is the fan you buy once and don't think about again for years - built to run continuously without drama. If you want your extraction sorted properly rather than something that starts rattling after a few months, this is where we'd point you.
Vortex Inline Fans are steel-bodied duct fans built for continuous grow room extraction, moving air through ducting to pull heat and stale air out of a tent or room. They're available across a range of sizes from 4" up to 12", with airflow scaling accordingly - Vortex's S-Line 6" model, for example, is rated at 347 CFM, the 8" at 728 CFM, and the 10" at 1081 CFM.
Construction uses double-insulated walls and a brushless AC motor with mixed-flow dual impellers to keep noise down while maintaining strong airflow, along with a high-impact polycarbonate casing, an integrated back-draft damper, and a mounting bracket for straightforward installation. Vortex backs the range with a 10-year warranty.
How it compares
Inline extraction fans are the backbone of most grow room ventilation setups.
- Compared with AC Infinity's Cloudline series, which also targets quiet-running grow room extraction, Vortex's double-insulated casing and mixed-flow impeller design aim at the same low-noise, high-airflow balance.
- Compared with a basic budget inline fan, the brushless motor and insulated casing on the Vortex range are built specifically to cut down on the vibration and noise that cheaper fans are known for.
- Compared with Vortex's own plastic-bodied Booster Fans, the Inline range is the primary extraction unit for a whole tent, sized well beyond what a booster fan is built to handle.
It sits in the mid-to-upper end of the extraction fan market - not the cheapest option, but backed by a 10-year warranty that reflects the build quality behind it.
Usage guidance
Size the fan to your tent volume and ducting before fitting.
Sizing
Choose a fan rated to move your tent's air volume several times per hour, accounting for a carbon filter and ducting length, which both reduce effective airflow from the fan's rated CFM.
Mounting
Fit using the supplied mounting bracket, positioned to pull air through your filter and ducting in the shortest, straightest run practical.
Running
These fans are built for continuous operation - pair with a speed controller if you need to dial back airflow rather than running full speed constantly where it isn't needed.
