Inlet chimney with recirculation

Especially for the real minimum ventilation the inlet chimney offers the possibility of an even more equal spreading of the fresh air. This specific system offers next to the air inlet the possibility of proportional recirculation of the existing, relative warm inside air. In cases of very big differences between the inside and outside temperatures this can be very important. By means of an adjustment flap easily the requested percentage of recirculation can be controlled. System is available in the diameter 640 mm.
