Air Lines
• Air lines link compressed air from one component to another.
• Air flowing from the Compressor moves down the Air Line or main
discharge line to the wet tank.
• Air lines are made of a durable, tensile material – they can withstand
pressure of at least 150 PSI.
• Application air lines (also known as service or control lines) have a
narrow diameter – Supply air lines (also known as delivery lines) have a
larger diameter.
