Operating specifications Condition of inlet air T=20°C, 0 m above sea level and p=1.205 kg/m3. Noise level Expressed as sound power LA IdB(A)] measured in free field with ducted fan, see pgs. 1.43 to 1.49. Orientations No.8 RD (clockwise viewed from transmission side) and No.8 LG. Fan in bolted orientable version for sizes 400-630, with front support and so not orientable for sizes 710 and above with transmission drive, always orientable for directly coupled fans without front support. See pg. 27. Special applications See pgs. 2.20 to 230. Fan start-up During start-up the fan flow rate must be limited, calibrated for the fan's maximum electrical input. Impeller classes The above table refers to standard operating conditions, in heavy-duty service conditions it is advisable to contact the CORAL Customer Service to establish the most suitable type of impeller.
