1x Prima Klima carbon filter 100mm, up to 240m ³/h

For an extra 400kr, you can replace the fan TT100 in this package for a fan TT100 with a built-in digital fan controller.
To change the speed of the fan, just change the cord's position between L1 and L2.
The cord attached to the N will always be there and you should never have L1 connected at the same time as L2!
