9 / 10

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

C) To increase the pressure of the compressed air

A) To cool the compressed air before use

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

D) To filter the compressed air

10 / 10

Why is it important to have an air receiver in a pneumatic control system?

A) It reduces the need for maintenance

C) It increases the efficiency of the compressor

D) It filters the air before it enters the compressor

B) It provides a reserve of compressed air and helps maintain a stable pressure in the system
