Can Airbox switch low pressures?
Yes. Use Airbox K. Connect a separate compressed air supply from a separate pressure regulator, to the 4mm input port on the top of the unit. With air pressure above 3bar applied to this port, the main valves will switch at low pressures, they will even switch vacuum. We refer to this supply as auxiliary or pilot air. Airbox K will operate normally (over 3 bar) using an internal pilot if the auxiliary line is not connected.
