7 / 10

What role does a pressure regulator play in a pneumatic control air supply system?

D) To cool the air before it reaches the control equipment

C) To filter moisture out of the air

A) To increase the air pressure to the maximum system limit

B) To maintain a consistent and controlled air pressure for the pneumatic control equipment

8 / 10

Why is it important to regulate the pressure of compressed air in a pneumatic control system?

B) To ensure the control equipment operates efficiently and safely without damage

C) To reduce the energy consumption of the compressor

D) To increase the air flow rate

A) To prevent the air from becoming too cold

9 / 10

Why is it important to filter compressed air before it is used in pneumatic control equipment?

D) To increase the pressure of the compressed air

B) To prevent contaminants from damaging or clogging control components

C) To cool the air to the desired temperature

A) To increase the speed of the air flow

10 / 10

What is the main purpose of an air receiver in a pneumatic control air supply system?

A) To cool the compressed air before use

D) To filter the compressed air

C) To increase the pressure of the compressed air

B) To store compressed air and provide a buffer to smooth out pressure fluctuations
