We are planning to use Pneumatic logic components. (81 550 001, 81 522 501, 81 503 720)
I would like to know if there is any specificaiton for CDA (Clean Dry Air) used with these components.
What degree of cleanness, dryness is needed?
Is there any recommendation about dew point or particle level?

Crouzet components are designed to be compatible with European standards. Clean Dry Air (CDA) is not specified, but would be a good guideline. Due to the small passages and orifice sizes of logic components, it is beneficial to component life to maintain dry air and minimize particles in the supply system.

The rules and regulations for use of Crouzet pneumatic components can be found at the back of the 2005 pneumatics catalog. Part of this section is included below.

European standard 983 (safety of machinery : safety of fluid power systems and their components) is a compatible with Crouzet pneumatic components. They can also be used within the scope of the European Community's machinery directive 89/392/EEC.

Crouzet Electro-pneumatic components are compatible with the European Community's low voltage directive 73/23/EEC and with European standards:

-EN 60 204 (safety of machinery : electrical equipment of machines), in accordance with International standard IEC 204-1

-EN 983 (safety of machinery : safety of fluid power systems and their components)

They conform to the European Community's EMC directive 89/336/EEC.
