Notes
*1 The FAD figures quoted correspond to 'Actual Volume Flow Rate' in accordance with ISO 1217
Ed. 4 (2009), guaranteed with a tolerance of +/-5 % for FAD < 250 l/s (530 cfm) or +/-4 % for FAD >
250 l/s (530 cfm).
FAD (Free Air Delivery) is measured at the above stated reference conditions.
The FAD figures are valid for supply voltage 400V (for 50Hz-units) or 460V (for 60Hz-units).
Data may differ 0,5% maximum at other supply voltages < 1kV and 3,5% maximum at supply
voltages > 1kV
*1 The SER figures quoted are in accordance with ISO 1217 Ed. 4 (2009),
guaranteed with a tolerance of +/-6 % for FAD < 250 l/s (530 cfm) or +/-5 % for FAD > 250 l/s (530
cfm).
The SER figures are valid for supply voltage 400V (for 50Hz-units) or 460V (for 60Hz-units).
Data may differ 0,5% maximum at other supply voltages < 1kV and 3,5% maximum at supply
voltages > 1kV
*2 A-weighted emission sound pressure level at the work station (LpWSAd).

Measured according to ISO 2151: 2008 using ISO 9614-2 (sound intensity scanning method).
The added correction factor (+/- 3 dB(A)) is the total uncertainty value (KpAd) conform with the test
code.
For air cooled machines, sound pressure levels are stated with ducting of outlet cooling air
according the installation proposal
*3 Unit data is valid at reference conditions
*4 Package current is the current a compressor uses

- at reference ambient conditions
- at 100 % load
- at max pressure
- at nominal voltage
- right before service interval (including fouled filters, etc).
*5 The pre-described fuses OR circuit breaker are maximum main fuses or circuit breaker to protect
the installed compressor electrical panel.
Cable and fuse or circuit breaker selection will depend on customer’s installation.
Fuses or circuit breaker of the same type/class are mandatory. Not installing these fuses or circuit
breaker will void warranty in case of an electrical failure.
Installing smaller fuses might lead to smaller supply cables. If Main circuit breaker shown as NA (not
applicable), only fuses are allowed.
