Mammoth TT Fan Kits - Exceptional Value for Money

Mammoth TT fan kits give you everything you need to remove hot, moist, CO2 depleted air from the grow space, and for very reasonable prices! You get the workhorse Mammoth TT fan, a matched Mammoth carbon filter, black combi ducting and some duct clips to connect everything up. Mammoth TT fans move a lot of air for the pricepoint, and come with two speeds, allowing you to control output levels straight out of the box. 

Mammoth TT Fans

Mammoth TT Twin Speed fans are low-cost solutions that still offer great performance. They are supplied with everything you need to get started - with no wiring or extra parts required. They also feature two speed settings so that you can gain some additional control over your environment before investing in a fan speed controller.

Running the Mammoth TT will help to control high temperatures by removing hot air from the grow space. At the same time, it will also remove excess moisture, and it will help to draw fresh air into the room, bringing with it a fresh supply of CO2.

Mammoth Carbon Filters

The Mammoth carbon filters included in these kits are specced to match the size and output rates of the TT fans. They will kill odours stone dead before they get the chance to leave the grow space, giving you complete peace of mind. Mammoth filters won't put too much of a 'drag factor' on fans, allowing as much airflow as possible without compromising on smells. They come with 50mm bed depths and utilise premium grade RC48 Australian carbon, which is regarded as the best source on the planet.

Combi Ducting

These kits come with black combi ducting, which is similar to traditional flexi ducting, but it's lined with plastic that makes it tougher and more resistant to tearing. Three duct clips are also included, which are used to connect up the system.

How To Use

How to Use the Mammoth TT Extraction Kit

Check out the following blog post for a visual guide to installing extraction systems.

You'll need to cut off a short piece of ducting and use it to connect the inlet end of the Mammoth TT fan to the carbon filter using two of the supplied duct clips. The other duct clip is used to connect the main length of ducting to the outlet end of the Mammoth TT fan.

Make sure that you hang the system at the top of your grow area (to remove hot air) and make sure that the ducting leads to an outside point. Try not to include any sharp bends in the layout of your ducting or you will reduce the effectiveness of your system.
