Mountain Air EC Whisper Fan 315mm – 12 Inch Inline Fan

Serious 12" Extraction Without the Roar

The Mountain Air EC Whisper Fan 315mm is an insulated, silenced inline fan that moves up to 2987 m³/h through 315mm (12") ducting. An EC motor gives smooth, stepless speed control and uses only the power needed for the speed you set, while a dual impeller and turbine-style inlet build pressure inside the housing so airflow holds up on longer or more complex duct runs. This version comes with a 2m IEC power lead and UK plug, hanging points and a dial speed controller.

Key Benefits

• 2987 m³/h maximum airflow - enough for large grow rooms and multi-light setups.
• Near-silent running - an insulated housing keeps noise down even at full speed.
• EC efficiency - brushless motor draws only what the chosen speed needs, with less heat and wear.
• Stepless speed control - dial controller included, any speed from low to maximum.
• Pressure where it counts - dual impeller and turbine inlet handle carbon filters and long runs.
• Ready to plug in - 2m IEC lead with UK plug and built-in hanging points.

Heat and Humidity Building Up?

Big lights and dense canopies push temperature and humidity up fast, and an undersized or noisy fan forces a choice between climate and a quiet life. Stale, humid air slows growth and invites mould. A high-output EC fan clears the heat and moisture and can be turned down when you need less, so the grow room climate stays steady day and night.

How to Use

• Plan the run: fit the fan after a matching 315mm carbon filter and keep ducting as short and straight as practical.
• Mount it: hang from the fixing points, airflow arrow pointing out of the room.
• Connect: plug the IEC lead into the fan and a UK socket, then set speed on the dial controller.
• Tune it: run just fast enough to hold your target temperature and humidity.
