Inline & Exhaust Fans
Inline & exhaust fans are the engine of your grow room ventilation — smart EC fans from AC Infinity, VIVOSUN, HVC and SigilVentus, sized to your tent and shipped Australia-wide.
Inline & Exhaust Fans That Move Air and Stay Quiet
Heat, humidity and stale air kill more grows than pests do. The right exhaust fan pulls it all out before it becomes a problem — and every fan here is stocked in Australia and backed by 14 years of hands-on growing.
Smart EC Inline Exhaust Fans, Controllers Included
Most inline exhaust fans in this range ship with a smart controller in the box — AC Infinity's Controller 69 Pro, VIVOSUN's GrowHub E42A, SigilVentus and HVC smart speed control. Set your target temp and humidity and let the fan do the thinking.
Sized by Calculator, Not Guesswork
An undersized fan cooks your canopy; an oversized one wastes power and makes noise. Run your setup through our Fan Size Calculator, then pick the matching unit — from 100mm micro-tent fans to full extraction systems.
Quiet Options for Stealth Grows
Silenced fans, EC motors that idle near-silent at low speed, and the Gardis Pro inline silencer for exhaust systems that need to disappear. Quiet airflow without giving up CFM.
Complete your airflow setup: carbon filters, clip fans & air circulation, grow tent accessories and the full grow room environment control range.
FAQs
What size inline fan do I need for my grow tent?
Match the fan's airflow to your tent volume, lights and carbon filter — as a rule, aim to exchange the tent's air every one to three minutes. Our Fan Size Calculator gives you the exact L/s and CFM for your setup.
Do inline fans work with carbon filters?
Yes. Inline and exhaust fans are designed to pull air through a carbon filter — just size the fan with the filter's resistance in mind, which the calculator accounts for.
Are EC inline fans quieter than AC fans?
Yes. EC motors run smoother and can throttle to low speeds without the hum of a traditional AC motor, which is why most smart fans in this range use them.
Welcome to The Grow Guys
We built The Grow Guys from the soil up — well, coco and perlite. Before we sold gear, we bought it, ran it, and learned the hard way what's worth the money and what ends up in the shed. That's the filter everything on our shelves passes through. No sales scripts, no rebadged junk, no telling you what you want to hear. Just gear we'd run ourselves and advice from people who actually grow. Chasing higher yields, tighter flowers, or your first harvest? You're in the right place.
