General description
Connection

Liner
Air is admitted through the air inlet duct and
enters the milk duct via the air bleed. The
air is needed for the transport of the milk to
the receiver. The air inlet holes are located
inside the inlet air housing placed on the
lower beam. Before the air enters the air
hoses connected to the air inlet ducts on the
rear side of the magazine, it is filtered in the
air bleed filter. All air in the VMS system is
filtered before it is put into use. The air is
then transferred further on through the milk
tube air inlet duct and finally it reaches the
air inlet hole in the connection piece.
Vacuum sensors
The vacuum sensors are placed on the air
inlet housing. At a kick-off, loss in vacuum is
immediately detected by the sensors. A
signal is sent to the shut off valves, which
shut off the vacuum.
