What is the purpose of a receiver in a Pneumatic system?
To filter the water
To increase the pressure
To accumulate the air to minimize starts and stops
To support the compressor
Air lines are usually lubricated to
avoid increasing pressure too much
reduce internal leaks and wear
create minimal air line flow
transport air contaminants and dirt
