Inlet 3- wall

This inlet consists of three single  inlets built on top

of each other. With three middle hinged inner valves the air

will be divided and also flows underneath the valves when

they are opened over 35%. The inlet is controlled by means

of three stainless steel side arms connected by a stainless

steel rod. This inlet is executed with curved inner valves so

when it is opened for maximum ventilation air is also guided

downwards to the animals.
