Aremove all but the frictional load of an air compressor at start-up
Bintensify the pressure developed by an air compressor during its normal running operation
Cpre-charge the cylinders of an air compressor prior to the start-up of the unit
Dopen the discharge valves during the compressor's operation to supply compressed air
AI Explanation
The correct answer is A) remove all but the frictional load of an air compressor at start-up. The primary function of the device illustrated in the image GS-0029 is to reduce the start-up load on the air compressor by removing all but the frictional load. This allows the compressor to start more easily and smoothly, preventing excessive strain on the system. The other answer choices are incorrect because they do not accurately describe the primary function of the device. Option B refers to intensifying pressure during normal operation, while options C and D describe functions related to pre-charging or opening the discharge valves, which are not the main purpose of the illustrated device.
