How to use
Fit the fan on the clean-air side of your carbon filter, so it pulls air through the filter and pushes it out along the ducting. The EC motor is made to cope with a filter and long duct runs, but every bend and metre of ducting still costs some airflow, so keep the run as short and straight as you can.
Browse the carbon filters and ducting, and see how to size a fan and carbon filter for your tent.
