The pressure drop that occurs with
increasing altitude does, of course,
have an effect on vacuum technology
or even on the vacuum generators
themselves.
Because the air pressure in the
atmosphere falls with increasing
altitude, the maximum attainable
differential pressure and,
consequently, the maximum
attainable holding force of a vacuum
suction gripper are also reduced. In
other words, the attainable vacuum
level of a vacuum ejector reduces with
increasing altitude. Nevertheless, the
performance level of 80% vacuum, for
example, remains unchanged
