matic actuators with 120 and 350 cm² actu-
ator areas (u AB 0100).
Vent plugs
Vent plugs are screwed into the exhaust air
ports of pneumatic and electropneumatic de-
vices. They ensure that any exhaust air that
forms can be vented to the atmosphere (to
avoid excess pressure in the device). Further-
more, the vent plugs allow air intake to pre-
vent a vacuum from forming in the device.
