Description
Serious extraction for large rooms, without the roar of rushing air
MDF Acoustic Box Fans house a powerful inline extractor inside a solid MDF acoustic casing that deadens the sound of rushing air while still shifting huge volumes of it. With airflow reaching up to 4,250 m3/h, they are built for growers running big rooms or multi-light tents who need real cooling and extraction without a fan that announces itself through the wall.
Key Benefits
- Airflow up to 4,250 m3/h, enough to cool and vent even the largest grow rooms and tents
- MDF acoustic casing is strong, durable and physically dampens fan and air noise at source
- Wide flanges make connecting ducting quick and leak-free at both ends
- Fitted power lead ready to run straight out of the box
- Four duct sizes, 6, 8, 10 and 12-inch (150, 200, 250 and 315mm) to match your extraction rate
- Twin Inlet model at 4,250 m3/h pulls from two 10-inch ducts into one outlet, so one fan can extract through two carbon filters or from two tents
Struggling to shift heat and humidity from a big grow space?
Large and multi-light setups build heat and humidity faster than standard fans can clear, and pushing a small fan flat out just makes noise without moving enough air. The high-output impeller handles that extra volume comfortably, while the MDF box absorbs the drone so extraction stays discreet.
How to Use
- Mount inline in your ducting run, connecting ducting to the wide flanges at each end
- Position to draw air out through a carbon filter or straight outside for odour control and cooling
- Plug the power lead into a timer, thermostat or fan controller so airflow ramps with temperature and humidity
- Site the box on a solid surface or brackets to keep vibration and noise to a minimum
Technical Specifications

Frequently Asked Questions
What does Twin Inlet mean?
A Twin Inlet box fan has two inlet collars feeding one outlet, so a single fan can pull air through two carbon filters, or from two tents or rooms, into one exhaust duct. The 10-inch Twin Inlet model moves up to 4,250 m3/h through two 10-inch inlets into a 10-inch outlet.
Which size do I need?
Match the outlet to your ducting and the airflow to the space: aim to change the air in the room roughly once every one to three minutes, then add headroom for a carbon filter, silencer and long duct runs. The 6-inch 1,500 m3/h model suits a compact run where a larger box will not fit; the 4,250 m3/h models are for big rooms and multi-light setups.
Can I control the fan speed?
Yes. These are AC fans, so run them through a mains fan speed or temperature controller rated above the fan's current draw – check the controller's amp rating against the model you choose.
