Essential Components For Inline Fan Setup

Ducting Tube: Ducting is clamped or taped onto your inline duct fan, acting as a channel to route the stagnant air away from your grow space.

Inline Fan: Inline fans help in circulating air within the indoor grow space.Maintaining consistent temperature and humidity levels, as well as distributing CO2 evenly.

Carbon Filter: Pulls the smell of plants from the air, catching the odor to neutralize it. Also used to trap pollen and spores, keeping the air clean.

Programmable Controller: Automate the operation of inline fans based on various parameters such as temperature, humidity, fan speed. This automation ensures that the fans operate at optimal levels.
