Air EC Inline Fan – 4" to 10" Quiet EC Extractor Fan

Air EC Inline Fan – Quiet Enough to Forget, Efficient Enough to Leave Running

Most people choose a fan by how much air it moves. Most people regret a fan because of how it sounds, and what it costs to run around the clock. The Air EC from Global Air Supplies is built for the second set of priorities. Its EC (electronically commutated) motor runs quietly from around 30dB, gives smooth 0–100% speed control with no humming or buzzing even at very low speeds, and uses less than half the power at half speed compared with a typical AC fan. It's an entry-level price for a fan that behaves like a premium one.

Perfect For

• Grow tents and rooms in bedrooms, flats and anywhere noise matters
• Plant rooms, propagation and mushroom chambers needing gentle, steady air exchange
• Drying rooms and cabinets where low, controllable airflow is key
• Growers wanting precise speed control and balancing between intake and extraction

Key Features

• EC motor: quiet, efficient, with no low-speed hum
• Smooth 0–100% speed control with an EC controller
• High-pressure mixed-flow design, built to pull through carbon filters
• Robust sealed body with built-in mounting brackets
• The motor and blades lift out while the ducting stays in place, making cleaning easy

Build the System

Pair it with a carbon filter rated above the fan's maximum airflow (we stock RAM, Rhino, MountainAir and Mammoth), and connect it with matching ducting. A silencer straight after the fan makes it quieter still.

🌿 Rose's Pro-Tip: the beauty of EC is running low and slow. Set your fan to 60–80% and you'll keep most of the airflow at a fraction of the noise and power. Turn it up only on the hottest days.
