Build a stable indoor growing environment with extraction and intake fans designed for grow tents, indoor gardens and larger grow rooms. Shop compact in-line fans, quiet EC extractor fans, high-pressure models and acoustically silenced options from trusted ventilation brands.
Effective air exchange helps remove excess heat and humidity while drawing cooler, fresh air into the growing space. Match your fan to the room size, carbon filter resistance and ducting layout, or ask our experienced team for practical advice before you buy.
Extraction and intake fans for controlled airflow
Ventilation is a core part of indoor climate control. An extraction fan removes warm, humid air from the room, while a correctly positioned intake supplies replacement air. Together they support more consistent temperature, humidity and air movement around your plants.
Our range covers straightforward budget fans through to efficient EC models and fully silenced units for installations where running costs, airflow control or noise levels are especially important.
Which type of ventilation fan do you need?
In-line extraction fans
In-line duct fans sit within the ventilation run and are a practical choice for many grow tents and indoor gardens. They are available in different diameters and airflow ratings, making it easy to match the fan to compatible ducting and filters.
EC extractor fans
EC fans use energy-efficient motor technology to provide smooth speed control and strong airflow with lower power consumption than many conventional AC alternatives. They are an excellent long-term choice for systems that run for extended periods or need precise environmental control.
Acoustic and silenced fans
A silenced fan places the motor and airflow path inside an acoustically treated casing to reduce operational noise. These models are well suited to larger rooms, high-airflow systems and installations where quieter performance is a priority.
Intake fans
An active intake fan draws fresh air into the lower part of the growing space. It can help larger rooms or restrictive ventilation systems maintain balanced airflow when passive intake vents alone are not sufficient.
How to choose the right fan size
Start with the volume of the growing space and the amount of heat and humidity that must be removed. Then allow for the resistance created by other parts of the system. A fan's quoted maximum airflow will reduce once it is connected to a carbon filter, long duct runs, reducers or several tight bends.
Before choosing a model, consider:
- The volume of your grow tent or room
- The heat and humidity load within the space
- The diameter and airflow rating of your carbon filter
- The length, diameter and number of bends in the ducting
- Your preferred noise level and energy consumption
- Whether the fan is compatible with your chosen speed or climate controller
For a filtered extraction system, use matching duct diameters and choose a fan with enough capacity to maintain useful airflow after resistance is taken into account. Our team can help you pair the correct components if you are unsure.
Complete your ventilation system
Build a complete installation with a correctly matched carbon filter, smooth or flexible ducting and accessories, compatible fan speed controller, and reliable temperature and humidity monitoring. Keeping component diameters and airflow ratings compatible will make the system easier to install and help it perform efficiently.

Extraction and intake fan FAQs
What is the difference between extraction and intake?
Extraction removes warm, humid air from the growing space. Intake brings replacement air into it. Smaller tents can often use passive intake vents, while larger or more restrictive systems may benefit from a powered intake fan.
Can I connect an extractor fan to a carbon filter?
Yes. Check that the fan and filter have compatible connection diameters and suitable airflow ratings. Remember that the filter and ducting add resistance, so usable airflow will be lower than the fan's unrestricted maximum.
Is an EC fan worth choosing?
An EC fan is a strong choice when energy efficiency, quieter operation and smooth speed control matter. A conventional AC fan may still be suitable for simpler installations or tighter budgets.
Should the extraction fan be mounted high or low?
Extraction is normally positioned toward the upper part of the space because warm air rises. Fresh-air intake is generally positioned lower down to encourage air to move through the growing area before it is removed.
