1.3. Air Requirements

1.3. Air Requirements
The air pressure supplied to the collet holder or gripper is important in ensuring that the material or tool is
released properly, or for the optional gripper, that the material is held securely.
If compressed air is used, it must be filtered to 1 micron, dry to 0º F dew point, and oil free.
l
If nitrogen is used, it must be 99.99% pure and filtered to 1 microns.
l
For stages equipped with a three-jaw gripper, air must be regulated to between 3 and 7 bar (45 and 100 psig).
Higher pressures could cause damage to the gripper assembly and should be avoided. The chuck becomes
fully open at approximately 4-7 bar (60-100 psig) depending on the collet size. Higher pressures will not
cause damage to the rotary union, but high flow rates will result. Because of the noncontact rotary union
design on collet-equipped stages, a small amount of leakage will occur. Approximate leakage rates of
between 10 Lpm (0.5 CFM) and 40 Lpm (1.4 CFM), depending on pressure, will be observed when the collet
is open.
