Particulate and gaseous contamination specifications
The following table defines the limitations that help avoid any equipment damage or failure from particulates and gaseous
contamination. If the levels of particulates or gaseous pollution exceed the specified limitations and result in equipment damage
or failure, you may need to rectify the environmental conditions. Remediation of environmental conditions is the responsibility of
the customer.
