General purpose
(1)
FAD (Free Air Delivery)
is actual flow rate at the compressor inlet measured at the discharge terminal point of the package in accordance with
ISO1217 Annex C.
(2)

inlet air at 40% relative humidity.
(3)
Sound levels are “free field conditions” per Pneurop PN8NTC2.3, +/– 3dB(A).
(4)
Always apply local electrical codes for sizing cables and fusing. In the absence of local codes the minimum cable size should be calculated on
basis of mean package full load current X1.25 (i.e. 25% margin)
