1)
Free air delivery is measured according to ISO 1217 ed.4 2009 annex D
Tolerance:
• +/- 5% 25 l/s (53 cfm) < FAD < 250 l/s (530 cfm)
• +/- 4% 250 l/s (530 cfm) < FAD
2)
To account for fuel used during regeneration the fuel consumption values have
to be increased with 1.5%. This is an average percentage and is dependent on
the working conditions of the compressor.
3)
Air required for engine and compressor element cooling, for combustion and
for compression.
