1. Fluid conditioning

2. Reservoir

3. Reservoir size The size of a compressed air reservoir depends on the: Delivery volume of the compressor Air consumption for the applications Network size (any additional requirements) Type of compressor cycle regulation Permissible pressure drop in the supply network

4. Reservoir sizing chart

5. Reservoir size

6. Maximum water content in air

8. Air dryers There are three auxiliary methods of reducing the moisture content in air: Low temperature drying Adsorption drying Absorption drying

9. Air driers, low temperature drying

10. Adsorption drier Silicon dioxide gel

11. Absorption dryer Chemical process, expensive, low efficiency

12. Air supply system

13. Service unit:

14. Compressed air filter Removes contaminants 5-µ

15. Pressure regulator

16. lubricator

17. Maintenance of air service units routine service measures are necessary on a regular basis. Compressed air filter: The condensate level has to be checked regularly, the level indicated in the sight glass must not be exceeded, this can result in the accumulated condensate being drawn into the air supply lines. The filter cartridge must also be checked for contamination and cleaned or replaced if necessary. Compressed air regulator: This requires no servicing, provided it is preceded by a compressed air filter. Compressed air lubricator: If fitted check the oil level in the sight glass and top up, if necessary, to the level indicated. The plastic filter and lubricator bowl must not be cleaned with trichloroethylene. Only mineral oils may be used for the lubricator.
