Pneumatic and Electrical Systems
- Pneumatic systems use compressors to store air under high pressure. When released, this pressurized air pushes on machine parts, making them move. Electric systems use electric generators to supply machine parts with power, which electric motors use to make parts move.
- Pneumatic machines can be made without using flammable parts or materials. Electricity is always a potential fire hazard. Pneumatic systems can operate even when the electricity goes out.
- Electrical systems need fewer specialized parts. Electricity is readily available in many places. Pneumatic systems need air compressors and other support equipment.
- Both pneumatic systems and electric systems are able to perform the same control functions. Both can function as switches, counters, relays, and logic systems.
