RAM EC Mixed-Flow Inline Fan – Quiet Inline Extractor Fan

EC efficiency and variable speed in one inline fan

The RAM EC Mixed-Flow Inline Fan combines a mixed-flow impeller with an EC (electronically commutated) motor that always runs at its optimum load, so it moves more air for less electricity than a conventional AC fan. It comes with a UK plug lead and variable speed control, in 8", 10" and 12" sizes rated at 1250, 1652 and 2206 m³/h.

Key Benefits

• Lower running costs – the EC motor matches its power draw to the load, a real saving on a fan that runs around the clock.
• More air and more pressure – greater air volume and static pressure than a comparable AC fan, so it copes with a carbon filter and longer duct runs.
• Variable speed – turn it down for quiet running at night or in cooler weather, up when the lights are hot.
• Much quieter than a traditional AC inline fan.
• Compact mixed-flow body – fits into tight grow tent and grow room layouts.
• UK lead supplied – ready to plug in.

Heat, Humidity and Stale Air

Without steady extraction a grow space quickly overheats under the lights, humidity climbs and fresh air stops reaching the canopy, which slows growth and invites mould. Because an EC fan can be dialled to exactly the airflow you need, you can hold temperature and humidity where you want them instead of running flat out or switching on and off.

How to Use

• Choose the size: match the fan to your ducting, and pair it with a carbon filter rated about 20% above the fan's free-air flow.
• Fit it: mount the fan on a firm support with the airflow arrow pointing away from the filter, and clamp the ducting to both spigots.
• Set the speed: start low, then raise it until temperature and humidity hold steady through the lights-on period.
