Vacuum Operation - Aerotech ANT95V-3 series Hardware Manual

Overview

1.4. Vacuum Operation

Aerotech can specially prepare the ANT95V-3 for operation in vacuum environments. Aerotech offers two
vacuum preparation options; one for low vacuum (for use in atmospheric pressures to 10
high vacuum (preparation for environments from 10
detail during modification, cleaning, and assembly results in products with optimal performance in vacuum
applications.
To ensure that the ANT95V-3 will continue to perform well in the vacuum environment, follow the guidelines
listed below (in addition to standard handling, installation, and lubrication guidelines outlined in this manual).
1. Do not remove the ANT95V-3 from the sealed bag until it is ready for use.
2. Always handle the ANT95V-3 in a clean environment and use powder-free polyethylene gloves to
prevent any contaminants from adhering to the surface of the ANT95V-3.
3. During installation, use cleaned, vented, stainless steel fasteners when securing the ANT95V-3.
4. Reduced air pressure eliminates significant convective heat transfer. This, coupled with the viscous
vacuum-compatible lubricants, could result in excessive motor operating temperatures. Because of
this, consider all continuous torque ratings to be 40 to 60% lower than the value specified for operation
in normal atmospheric environment. Reduce motor usage accordingly.
5. For vacuum applications, the recommended lubricant is a small quantity of
or a compatible substitute of equal quality.
6. Baking vacuum components between 100 and 125 °C for 24 to 48 hours significantly reduces
outgassing at initial pump-down to vacuum pressure and evaporates water vapor that impregnates
porous surfaces on the aluminum surfaces and Teflon cables. Aerotech recommends that customers
bake out vacuum systems when first installing them in the vacuum chamber.
