DIE017EN - 05.06.2019
The pneumatic system is composed of two components. The system section (X)
and the sealing air section (Y). To ensure trouble-free operation, periodic checks of
the pneumatic system are necessary.
- Check oil level at oiler (optional).
- Check supply and fluid lines.
- Check silencers.
- Replace filter.
- Drain condensate (not applicable to auto-drain).
- Check the pressure settings on the pressure gauges (system and sealing air).
Due to different requirements and/or specifications of the respective
manufacturers, be sure to review the respective manufacturer's
documentation!
Example: G220 Pneumatic maintenance unit by Festo
The following components are used on the system maintenance unit (X) and the
extension for sealing air on the glass scales (Y):
1. Switch-on valve (manual)
2. Pressure regulating valve for system pressure 6–8 bar
3. Pressure gauge for system pressure
4. Filter insert with retained particle size 40 µm with automatic condensate drain
5. Filter insert with retained particle size 5 µm with automatic condensate drain
6. System pressure monitoring
7. Electrically actuated switch-on valve
8. Pressure sensor for pressure differential monitoring
9. Microfilter insert with retained particle size 1 µm with automatic condensate
drain
10. Filter insert with retained particle size 0.01 µm with automatic condensate drain
11. Activated carbon filter no automatic condensate drain
