Main advantages: The wall inlets of the CL series are made of shock-proof, recyclable, non-deformable, UV-stabilised plastic and can easily be cleaned with a high-pressure cleaner. The insulated inlet flap is kept in a closed position by rustproof steel springs, thus sealing the building airtight. The inlet flap is pulled open. This allows the farmer to regulate the inlet opening very precisely in each season. As an example from the winter season: the cold, outside air enters the building, immediately combining with the warm, inside air. This process helps create a more comfortable climate for the animals and can easily be managed with a control set. This control set opens the fresh air inlets either all at once or individually.

Main advantages: The CL 1540 is a multi-purpose ceiling inlet. The materials of this inlet are made of recyclable, shock-proof, non-deformable and UV-stabilised plastic. Rustproof steel springs keep the insulated inlet flap closed. The ZED 5000 inlet is made of polyurethane and is equipped with a flange so it can be fastened to the ceiling. This inlet can produce very high air rates and is therefore especially well suited for additional summer ventilation when combined with a DiffAir ceiling (combi-diffuse ventilation).

A universal method for supplying fresh air. Main advantages: Due to their modular design, perforated air channels are suitable for nearly every house type with an inserted ceiling below the attic. They are available in five different widths and consist of heat-insulated polyurethane (PU) plates. The individual hole pattern of the perforated plate ensures optimum fresh air ventilation throughout the house. Furthermore, this system guarantees an ideal adaptation to maximum summer air temperatures or conditions. The PU plates can also be used as partially or completely perforated ventilation ceilings.
