Fresh air inlet »ZEW« 2500 / 5000

The wall air inlets in this range comprise insulated polyurethane rigid foam. Cleaning is easy due to the smooth, hard surfaces. The integrated sealing lip reliably closes the inlet so that heat losses via the opening are avoided. Numerous inlets are available, also with a bowed flap (“M”-variant), in order to split the incoming fresh air before feeding it into the animal area.

The inlets differ in terms of air capacity and installation size. DLG-tested system (DLG test report 4919 and 4920).


All inlets are available in the opening variants “automatically closing” and “automatically opening”. Depending on the range a version with rear extension and an “M-variant are also available.


  • Bird protection grid
