6.5. Air Supply
Air Requirements
The A-62x stage requires clean, oil-free, and dry compressed air to operate properly. See Section 10.2 for
detailed air supply requirements.
It is recommended that a pressure switch is installed to monitor air supply pressure and to remove power from
the stage motor if supply pressure drops below 40 psi to prevent damage to the air bearing surfaces.
The air inlet fitting to the A-62x stage accepts flexible polyurethane pneumatic tubing:
4mm OD for the model A-621 & A-623
6mm OD for the models A-624, A-625 & A-627.
Figure 5 - Air Inlet Fitting Location
Figure 6 - Air Exhaust Port Location
As air flows through the stage, it must eventually exhaust to atmosphere. There is an
exhaust port located on the side of the stage. Do NOT allow this exhaust port to
become blocked or covered.
Turning off the air supply when not in use
When the stage is not in use, the air supply may be turned off to preserve compressed air and energy.
The stage table should never be moved without the air supply turned on. Moving the
stage table with no air supply, causing sliding metal-to-metal contact, may damage the
bearing surfaces.
