Air Generation System

1. Compressor is a mechanical device where it produces high
pressurized air by reducing its volume. Temperature of a gas
naturally increases when compression occurs. Air enters to the
compressor at atmospheric pressure and compressed at a higher Air generation system
pressure and delivered to the pneumatic system. During
compression, mechanical energy is transformed into pneumatic
energy.

2. Electrical motor is used to supply mechanical power to the
compressor by transforming electrical energy into mechanical energy.

3. Pressure switch is a device that controls the operation of electric
motor. This switch is set to a maximum pressure so that it stops the
motor when pressure in the tank reach its maximum limit and starts
the motor when minimum pressure is detected in the tank.

4. Check valve is used to ensure air from the compressor into the tank
is in one way and prevents the air leaking back when the compressor
stop works.
