Mammoth TT Grow Room Fan
Use a Mammoth TT Twin Speed Inline Fan and choose between two available settings for the air flow rate of your extraction system, making adjustments as and when required to take account of different temperatures over the course of the year. All it takes is the flick of a switch!
There are 4 models in this plug and play range, catering for every size and type of hobby grower. Pleasingly you’ll find each of the high pressure TT fans feature quality components, offer up thermal overheating protection and include a 2 year manufacturer’s warranty. Very little noise emits from these products, an IP65 rating indicates dustproofing and waterproofing properties, and a quick release mechanism allows for easy cleaning too! Furthermore, you don’t need to wire up a Mammoth TT Twin Speed Inline Fan and you don’t need to purchase a separate power lead (one is supplied).

Which air flow is right for you?
Every hour your Mammoth TT Twin Speed Inline Fan operates, it should be able to shift a certain amount of air, with a number of factors having a bearing here, like the shape and size of your grow room and the quantity, power and type of lighting being operated. Now, don’t worry if this sounds confusing – a rough guide to finding a suitable model is outlined below:
- 100mm (4”) Mammoth TT Twin Speed Inline Fan (165m3/hour or 198m3/hour) – up to 1 x 400W light
- 125mm (5”) Mammoth TT Twin Speed Inline Fan (248m3/hour or 284m3/hour) – up to 1 x 600W light
- 150mm (6”) Mammoth TT Twin Speed Inline Fan (410m3/hour or 530m3/hour) – up to 2 x 600W lights
- 200mm (8”) Mammoth TT Twin Speed Inline Fan (530m3/hour or 690m3/hour) – up to 4 x 600W lights
Which carbon filter works best with your fan?
When you decide to purchase the individual components of an extraction system, you must ensure your Mammoth TT Twin Speed Inline Fan and the intended carbon filter and ducting are compatible. Again, see the list below for our suggestions:
- 100mm (4”) Mammoth TT Twin Speed Inline Fan (165m3/hour or 198m3/hour) + 100mm (4”) BAY6 Carbon Filter – 300mm length (max air flow 350m3/hour)
- 125mm (5”) Mammoth TT Twin Speed Inline Fan (248m3/hour or 284m3/hour) + 125mm (5”) BAY6 Carbon Filter – 300mm length (max air flow 430m3/hour)
- 150mm (6”) Mammoth TT Twin Speed Inline Fan (410m3/hour or 530m3/hour) + 150mm (6”) BAY6 Carbon Filter – 300mm length (max air flow 470m3/hour)
- 200mm (8”) Mammoth TT Twin Speed Inline Fan (530m3/hour or 690m3/hour) + 200mm (8”) BAY6 Carbon Filter – 600mm length (max air flow 1125m3/hour)
What is needed to create an extraction system?
To create a complete extraction system, combine your Mammoth TT Twin Speed Inline Fan with the following products (in suitable sizes):
- Carbon filter – which stops unpleasant odours leaving the grow space
- Length of ducting – which carries and directs the air
- Duct clips – which are used to connect ducting to the exhaust end of your fan and sometimes to connect ducting between the intake end of your fan and filter
- Fast clamp – which is used to connect the intake end of your fan and filter in the most secure way possible
- Hanging accessories – which usually consists of a combination of chain and s-hooks or alternatively rope ratchets (recommended)
- Fan speed controller – which is not essential, but does prove the best way to manage your extractor fan
How do you piece together an extraction system?
Broadly speaking, there are two options for configuring an extraction system:
1.) Carbon Filter > Fast Clap > Extractor Fan > Duct Clip > Ducting (recommended)
2.) Carbon Filter > Duct Clip > Ducting (short) > Duct Clip > Extractor Fan > Duct Clip > Ducting
Where should you locate your extraction system?
In terms of where to locate your extraction system, we recommend hanging it at the top of the growing area, with the air exiting the tent or room from an opposite corner of where you intend to bring fresh air in – typically via an intake fan or open vent(s) positioned low down. This arrangement prevents you from immediately extracting away the fresher air coming in.
What about air intake?
For best results and the most effective ventilation setup, you should draw in around 20% less air than you extract. In a tent, this stops air seeping out before it’s been through your filter. Users of small-to-medium sized tents can get away with just opening up the vents to allow enough air in, but we recommend installing an active intake system for tents measuring 1.2m x 2.4m and above. A Mammoth TT Twin Speed Inline Fan will work well for this task too – simply pick the model below your extractor fan and combine with suitable sized lengths of ducting and duct clips.
