Test

Procedure:

Install a water manometer (gauge) to read the pressure at the air inlet fitting
on the compressor. If the compressor shares the engine air intake system
then restrict the engine air filter such that at rated engine power and speed
the engine is at its maximum allowable inlet restriction for a dirty filter (see
the engine data sheet). Under this condition operate the engine at rated
speed and power and read the pressure at the compessor air inlet fitting
while the compressor is loaded/pumping.
