1) At reference conditions, if applicable, and at normal shaft speed unless otherwise
stated.
2) Free Air Delivery (volume flow rate) 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
The international standard ISO 1217 corresponds to following national standards:
• American ANSI PTC9
• British BSI 1571 part 1
• German DIN 1645 Part 1
• Swedish SS-ISO 1217
3) Air required for engine and compressor cooling, combustion and for compression.
