I´ve really got no idea witch brand fan that is. It´s an about 3 inch fitting to the fan witch sucks the air thru the carbon scrubber and blows the excess air thru the cooltubes. The fan is about 100 cubic meters per hour air flow.

Got an 80 cubic meters per hour air intake on the side of the cabinet, so I always got some under-pressure in the room that insures that the smell stays where it needs to be. An ceramic (no glowing coil in the dark period) electric heating fan with thermostat in the room for air circulation and an constant temperature.
