Recommended 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 compressor
air inlet fitting while the compressor is loaded/pumping.
Measured compressor air inlet restriction:
(measured at compressor at rated engine speed and power with a dirty filter.)
